Snorkelling In Phang Nga

Phang Nga is one of Thailand’s most inviting snorkelling destinations, where nature, ease of access and vibrant marine life come together in perfect balance. With the Andaman Sea lapping gently at its shores, this region offers a peaceful alternative to busier tourist hubs, ideal for both casual explorers and dedicated underwater enthusiasts. The waters here are typically calm and shallow, making them well-suited to beginners and families, yet rich enough in biodiversity to captivate more seasoned snorkellers.

From towering limestone karsts rising from emerald bays to secluded coves fringed with coral, the coastline is a patchwork of natural beauty. Brightly coloured fish dart through the reefs, sea turtles glide past gently waving anemones, and in certain seasons, even larger visitors like manta rays or whale sharks may pass through.

Aleenta Phuket – Phang Nga Resort & Spa sits in a prime position for discovering these aquatic treasures. Nestled along Natai Beach, the resort offers access to many of the region’s top snorkelling locations, including the famed Similan and Surin Islands. Whether you prefer to step into the sea from a quiet beach or join a guided boat excursion, Aleenta provides a relaxing and luxurious base for days spent exploring the underwater world.

Snorkelling in Khao Lak

Khao Lak is one of the most accessible and enjoyable regions for snorkelling in Phang Nga, particularly appealing to families, beginners, and those who prefer relaxed coastal exploration. Stretching over 25 kilometres, its coastline offers a variety of beaches, each with its own character — from rocky inlets to wide sandy stretches. The shallow, often calm waters along this part of the Andaman Sea make it easy to enter and explore, whether you’re wading in from the shore or heading out on a short boat ride to nearby reefs.

With several offshore snorkelling sites close by, and a good selection of beach-access spots, Khao Lak presents a user-friendly and visually rewarding introduction to the region’s marine life.

Khao Lak Beach

This long, gently curving beach is known for its peaceful setting and spacious sands. With calm waters and rocky sections just offshore, Khao Lak Beach offers an easy, walk-in snorkelling experience. While not as coral-rich as offshore islands, you may spot schools of small reef fish and the occasional curious crab weaving between the rocks. It’s a good starting point for those wanting a quiet introduction to snorkelling.

Bang Niang Beach

Sitting just to the north of Khao Lak Beach, Bang Niang is a broad, sandy stretch with a gentle slope into the sea. It’s ideal for families, with safe, shallow water that’s easy for children to enjoy. While the visibility can vary depending on tides and recent weather, there are still pockets of interest where fish gather near rocky areas. The beach is also known for its sunset views and laid-back atmosphere.

Sunset Beach and Khuk Khak Beach

These lesser-known beaches are set apart by their remoteness. Sunset Beach, just south of Khao Lak town, is framed by lush greenery and dramatic rock outcrops. Khuk Khak Beach, further north, feels even more remote. Both offer pockets of rocky terrain in the shallows where snorkellers may spot colourful fish. Thanks to the sheltered conditions and lower footfall, they’re often quieter and offer a more relaxed experience.

Pakweeb and Bangsak Beach

Further north along the coast, Pakweeb and Bangsak beaches are known for their soft white sands and inviting water. These beaches are wonderful during the dry season when the sea is clearest and most inviting. Just offshore lies Laem Pakarang, or Coral Cape – one of the area’s top snorkelling departure points. From here, boat trips can take you to nearby reefs rich with coral and marine life. Back on shore, the atmosphere is peaceful and unspoilt, with only a few beachside restaurants and resorts adding to the charm.

Together, these locations make Khao Lak an excellent option for snorkelling, whether you prefer to stay close to shore or venture slightly further out for a richer underwater experience.

Snorkelling in Phang Nga Bay and Marine National Parks

 

Phang Nga Bay

Phang Nga Bay is most famous for its towering limestone cliffs and cinematic scenery, but beneath the surface lies a lesser-known world of snorkelling potential. The bay’s protected waters are generally calm, and between December and April, conditions are at their clearest, offering the best visibility for marine exploration. Unlike the bustling area around James Bond Island, the bay is dotted with quieter, islands where coral reefs and small marine ecosystems thrive.

These smaller islets and coves offer excellent opportunities for snorkelling, particularly for those who prefer a peaceful setting away from the crowds. Guided boat trips and private charters from Aleenta or local tour operators can take you to hidden spots with coral gardens, rock ledges and sheltered shallows teeming with colourful fish. Kayaking and longtail boat tours often include time to snorkel in these calm inlets, combining surface exploration with time in the water.

Ao Phang Nga National Park

Covering a vast stretch of both land and sea, Ao Phang Nga National Park protects one of Thailand’s most ecologically significant marine environments. The park is home to a complex web of mangroves, seagrass beds, and shallow coral formations that serve as nurseries for countless marine species. These ecosystems play a vital role in maintaining the balance of the bay’s biodiversity and are monitored to ensure their preservation.

Snorkelling in the park is best done as part of a boat tour, with guides who know where to access the healthiest coral and clearest water. Many trips include stops at secluded beaches or island coves where snorkelling is permitted. The marine life here includes schools of tropical fish, small reef sharks, and occasionally sea turtles — particularly in the seagrass-rich shallows.

As a protected area, there are clear guidelines in place to minimise environmental impact, including restrictions on anchoring and interaction with marine life. Respecting these helps preserve the bay for future generations while ensuring an authentic and responsible experience.

Suthep Bay (Kuraburi)

Located off the coast of the Kuraburi district to the north of Phang Nga, Suthep Bay is an offshore snorkelling spot suited to confident swimmers and those with some experience in open water. The bay’s wide, open character means it can experience stronger waves and swell compared to more sheltered areas.

What makes Suthep Bay stand out is its remarkable coral formations. Large stands of tall coral, some reaching over a metre in height, create an underwater landscape that is both dramatic and biologically rich. Deeper sections between 8 and 15 metres reveal dense coral beds, while the shallows offer glimpses of giant sea fans swaying in the current.

While marine life in terms of fish may be less concentrated than in other parts of the region, the diversity and scale of the coral make this site a rewarding choice for those seeking a more adventurous snorkelling excursion. It’s advisable to visit as part of an organised tour with proper safety guidance, particularly when sea conditions are less predictable.

Snorkelling around Surin Islands

The Surin Islands, located further north off the coast of Phang Nga, form part of a protected marine national park and are considered among the best snorkelling destinations in Thailand. Known for their clear water, healthy coral reefs and rich marine biodiversity, the Surin Islands offer a more immersive underwater experience, particularly appealing to nature lovers and those seeking off-the-beaten-path adventures. These islands are typically accessed by boat from Kuraburi or Khao Lak, with day trips and multi-day excursions available during the dry season from November to mid-May.

Chong Khad Bay

Positioned between the North and South Surin Islands, Chong Khad Bay offers a blend of accessible snorkelling and scenic beauty. Just a short walk from the island’s national park headquarters, this bay is often the first stop for visitors arriving by boat or staying at the island’s designated camping area.

Chong Khad Bay was once celebrated for its lush, soft corals, purple sea flowers, and large schools of clownfish and butterfly fish. While some areas were impacted by natural disturbances such as the tsunami, there are still vibrant sections of reef worth exploring. The depth averages around three metres, but strong currents can develop as the tide changes, so it’s best visited with a guide who knows the tidal patterns. Even now, careful snorkellers can witness flashes of colour beneath the surface as marine life continues to return.

Mai Ngam Bay

Located along the northwest coast of North Surin Island, Mai Ngam Bay is a sheltered spot known for its calm waters and reef access directly from the beach. During low tide on new or full moon days, visitors can wade out to the coral from the sand. At high tide, it becomes a leisurely swim to reach the reef areas, which lie roughly 200 metres offshore.

The coral reef here, though not as deep or dramatic as some of the offshore sites, is excellent for observing smaller fish species and reef formations in a safe, relaxed setting. The bay is ideal for families, beginners and those who want to combine snorkelling with walking trails or a peaceful beach afternoon. A footpath connects Mai Ngam Bay to the island’s campsite, and boat access is also possible.

Ao Chak, Ao Pakkhad, and Ao Tao

These three bays offer some of the most diverse snorkelling experiences within the Surin Islands, each with its own highlights and marine inhabitants.

Ao Chak sits further from the main landing areas, and its coral fields are located around 400 metres from shore. The reefs are made up of staghorn and Kon coral, with sea fans and small reef fish found along the slope. This is a good spot for snorkellers with moderate experience looking to explore more complex underwater terrain.

Ao Pakkhad lies just south of Ao Tao and features extensive fields of Pakkhad coral, creating a striking underwater landscape. The reef is parallel to the shoreline, and as you swim along, you may encounter butterfly fish, jorake fish and various species of Sinsamuter fish. At the deeper edges of the reef, divers and snorkellers have occasionally spotted leopard sharks resting on the sandy seabed. Sea fans decorate the deeper zones, offering an extra layer of colour and movement.

Ao Tao is one of the most exciting snorkelling locations in the Surin Archipelago, known for its vibrant coral diversity and high chance of encountering larger marine species. The reef here supports both soft and hard corals, including impressive formations of Kon coral and sea fan clusters. Named after the Thai word for turtle, Ao Tao is regularly visited by hawksbill sea turtles and has also gained a reputation for occasional sightings of whale sharks and manta rays — making it a bucket-list location for many underwater explorers.

Collectively, the Surin Islands provide a spectacular snorkelling experience for those willing to venture a little further. With healthy reefs, abundant wildlife and knowledgeable local guides, these islands remain one of Thailand’s most treasured marine environments.

Snorkelling in Phuket

Phuket may be best known for its sweeping sandy beaches and lively resorts. Still, for those willing to explore a little further, the island reveals a rich variety of snorkelling spots tucked among its rocky headlands and hidden bays. These coastal pockets offer access to vibrant reefs, calm waters and an abundance of marine life – all within easy reach of Aleenta Phuket.

Unlike the more commercialised beachfronts, many of Phuket’s best snorkelling locations are peaceful and relatively uncrowded, particularly outside of peak season. Some require a short walk or boat ride to reach, but the rewards are clear: calm waters, colourful coral gardens and encounters with reef fish, sea anemones and occasionally sea turtles. Ideal for day trips or a change of scenery from Natai Beach, these snorkelling spots allow guests to explore another side of the island’s natural beauty.

Ao Sane Beach

Tucked behind the headland near Nai Harn, Ao Sane is one of Phuket’s best-kept snorkelling secrets. This small beach is divided into a series of rocky coves, giving it a secluded feel and naturally creating snorkelling-friendly conditions. The reef begins just metres from the shore, with clear water and healthy coral that attract parrotfish, wrasse, and the occasional moray eel. Equipment can usually be rented nearby, and a beachfront restaurant makes it easy to spend a few hours here.

Ya Nui Beach

Located between Promthep Cape and the Windmill Viewpoint, Ya Nui is a compact and charming cove that’s easy to miss but well worth the visit. Its sheltered setting makes it ideal for snorkelling, with gentle waves and a reef that wraps around the headland. A short swim from the beach leads to rocky outcrops where reef fish gather. Despite its size, Ya Nui offers a surprisingly good variety of marine life, including butterfly fish and small reef species.

Naithon Beach

On the quieter northern stretch of Phuket’s west coast, Naithon Beach offers a peaceful escape from the busier resort areas. The southern end of the beach is perfect for snorkelling, where rocky areas give way to coral and seagrass. The marine life is modest but diverse, and the calm conditions make it a relaxing spot for a morning or afternoon swim. It’s an excellent choice for those staying on the island’s north side or looking to escape the crowds.

Merlin Beach

Positioned just south of Patong, Merlin Beach is one of the few places in Phuket with a natural reef directly offshore. While located in front of a major hotel, public access is still possible via a nearby road. The reef is shallow and easy to reach, with patches of coral that are home to clownfish and other small reef dwellers. The beach itself is relatively small, but it remains less crowded than nearby Patong and offers a quieter snorkelling experience.

Banana Beach

Banana Beach, located between Bang Tao and Nai Thon, is one of Phuket’s most picturesque hidden beaches. The clear turquoise water and lack of strong currents make it ideal for snorkelling, especially near the rocky ends of the beach. The reef is alive with small fish, sea urchins and the occasional squid. Getting here requires a short walk down a steep path, but the reward is a tranquil bay that feels far removed from the busier parts of the island.

Freedom Beach

Accessible only by boat or a steep footpath, Freedom Beach remains one of the most untouched spots near Patong. It’s open seasonally and best visited during the dry months when the water is calm and visibility is high. The snorkelling is best at either end of the beach, where rocky ledges attract colourful fish. With powdery sand and a quiet setting, it’s a peaceful place to combine beach time with time in the water.

Laem Ka Beach

Located on the southeastern tip of Phuket near Rawai, Laem Ka is a sheltered beach with calm, shallow water. Rocky formations along the shoreline provide a suitable habitat for marine life, and the easy entry makes this a convenient spot for beginners. The beach is lesser known and has a tucked-away feel, ideal for a slow afternoon of snorkelling and relaxing.

Kata Noi and Paradise Beach

At the northern end of Kata Noi, snorkelling is excellent thanks to the natural protection of the headland. The coral here attracts a wide range of reef fish, and the beach’s quieter vibe makes it suitable for longer, more leisurely swims. Paradise Beach, close to Patong, is more developed and can be busy during high season. However, snorkellers can still enjoy good visibility and a variety of marine life near the rocks, particularly during the early part of the day.

From hidden coves to coral-fringed headlands, Phuket’s snorkelling scene is full of variety and charm – ideal for day trips from Aleenta or as part of a longer coastal exploration.

 

Seasonal Advice and Conditions

 

Best Time to Snorkel

For the most enjoyable snorkelling experience in Phang Nga and Phuket, the best time to visit is between December and April. During these months, the sea is typically calm, the skies are clear, and underwater visibility is at its best. These conditions make it easier to explore coral reefs and observe marine life without strong waves or sediment clouding the water. This is also the ideal season for trips to the Similan and Surin Islands, as boat services operate regularly and the marine parks are open to visitors.

From May to October, the region experiences the southwest monsoon, bringing stronger winds, heavier rainfall and rougher seas. Visibility can be poor due to stirred-up sediment, and boat tours are often limited or suspended, particularly in the national parks, which close for conservation and safety reasons. While some sheltered beaches on the mainland may still offer snorkelling opportunities during this period, conditions are unpredictable and less suitable for offshore trips.

Tides and Safety Tips

Tidal changes play a significant role in snorkelling safety and visibility, especially in areas like Chong Khad Bay in the Surin Islands, where shifting tides can cause strong currents. Snorkelling at low tide may also expose sharp coral or reduce access to deeper reef sections, while high tide can bring better coverage but stronger water movement.

When visiting unfamiliar or remote locations, it’s strongly recommended to snorkel with a local guide or as part of a guided tour. These experts not only know the safest routes and best visibility windows but can also help identify marine life and share insight into local ecosystems.

Additional tips:

• Always wear a rash guard or reef-safe sunscreen to protect your skin and the coral
• Avoid touching or stepping on coral to preserve fragile reef systems
• Check weather forecasts and sea conditions before planning an excursion
• Bring water, sun protection and appropriate gear, or enquire with Aleenta’s concierge for support arranging snorkelling trips with equipment included

Understanding seasonal patterns and staying aware of tidal shifts ensures a safer and more rewarding snorkelling experience across Phang Nga and Phuket.
