A couple of months ago I posted a short article about my upcoming visit to Boulder Island. The island forms part of the Myeik Archipelago in the Andaman Sea, which lies west of southern Myanmar and Thailand.

At that time, I introduced you to the Boulder Bay Eco Resort on Boulder Island which is locally known as Khin Nyo Gyi Island. This island is easily accessible by boat from Ranong on the west coast of Thailand so we do not have to travel via Yangon, the capital of Myanmar.

From Ranong, take a 20-minute longtail boat to Kawthaung, the southernmost town of Myanmar. The town itself is quite pleasant and a great introduction to life in Myanmar, especially if you have never been to Myanmar. If you have a nite or more to spare, check into the lovely Victoria Cliff Hotel & Resort located a few minute’s drive outside of town. See my review of both these resorts below in this post.

I was extremely fortunate to be invited by both resorts, so in September (2023) I took a pleasant overnight bus from Bangkok to Ranong. I arrived early in the morning and then took a taxi for a short drive to the Ranong pier, where I had breakfast in one of the many authentic Thai restaurants. The Thailand immigration office opened at 8 AM and just a few minutes later I was on the longtail boat which took about 20 minutes to cross the river over to Kawthaung, Myanmar.

I have done this river crossing several times in the past, and it was so nice to be back in Myanmar, one of my most favoured countries. The people here are just the best! I stayed two nights in the Victoria Cliff Hotel & Resort, and then one night in the Honey Bear Hotel located right by the pier from where the boat of the Boulder Bay Eco Resort would depart at 8 AM the next day. It was great to spend the evening in Kawthaung so I could explore the market and stock up on a lot of snacks for my stay on Boulder Island. The next morning I helped the staff of the island resort to load the boat with bags of rice and lots of food. By 9 AM we were on our way to Boulder Island for a very pleasant journey.

The Mergui Archipelago, locally known as the Myeik Archipelago, is an unspoiled paradise and one of my favourite places on our planet.

From high above the archipelago, the islands appear to form three vague strings, spread out over many miles. Located in the westernmost reaches of the archipelago, about 85 kilometres (53 mi) west of mainland Myanmar and Thailand, Boulder Island is remote and pristine, earning its name from the gigantic rounded boulders scattered along its shores, some stacked into gravity-defying formations like immense stone sculptures.

Beyond its bizarre rocky landscapes, Boulder Island’s interior harbours lush jungle while idyllic beaches tucked into protected coves are scattered along the coast. With no villages or roads, and only one small eco-resort, Boulder Island remains virtually untouched by civilisation.

Its isolation and lack of development means clear waters and intact coral, making Boulder Island one of the archipelago’s finest snorkelling and diving destinations. Look out for juvenile black tip reef sharks, sea otters, and large schools of small fish right in the shallows near the beach!

Jungle trails connect all eight beaches—your escape routes to a hidden paradise of beauty and solitude. 

Each one reveals new surprises from gravity-defying boulder formations to secluded snorkelling spots and beautiful shells. They share soft white sands and crystal clear turquoise waters. The trails also lead to lookout points for panoramic views over the island.

This rugged and unspoiled island is excellent for birding with a diverse array of bird species—spot the white-bellied sea eagles, Brahminy kites, Nicobar pigeons and many more. The chirpy white-rumped shama will unquestionably wake you up early with its beautiful songs. 

Harmless monitor lizards and reticulated pythons also inhabit the jungles, but fortunately, no dangerous animals or insects have been identified making it perfectly safe to explore.

The island’s only accommodation is the privately owned solar-powered Boulder Bay Eco Resort tucked behind the lush fish poison trees and screw pines of Boulder Beach. This small, cosy resort was built to sustainably integrate into the island’s ecology.

After being invited to visit, I boarded the resort’s boat in Kawthaung, Myanmar’s southernmost town. On the pleasant five-and-a-half hour journey to Boulder Island, we passed many beautiful islands and beaches, mostly uninhabited. A speedboat can be arranged for a faster trip.

As the boat approaches the southern side of the island with its distinctive piled-up boulders in the shallow waters, you will see the resort‘s well-camouflaged beachfront bungalows peeking behind the trees. 

At high tide, you can disembark right onto the beach. During low tide, the boat moors at the concrete jetty which extends beyond the exposed corals. Depending on the conditions, you may need to be chauffeured to the jetty or beach by rubber dinghy or two-person kayak.

Bamboo Beach Boulder Island Myanmar
Bamboo Beach is on the west side (facing south), Boulder Island.

The friendly staff will welcome you with an ice-cold drink at the resort’s spacious thatched-roof community centre and check you into your bungalow after a short briefing. With open sea views, the community centre is a place to relax while dining, enjoying the bar, accessing the satellite internet, and playing card games with other adventurers. 

Welcome to paradise!

The resort offers eight eco-friendly seafront bungalows with another twelve amongst the trees. Constructed in the traditional Burmese style with wooden frames and walls, and local palm-leaf roofs, none of the building materials other than bamboo have been harvested from the island. 

The ample supply of fresh water is pumped from a well and meticulously filtered to ensure it is clean and safe to drink. Close to the adjacent beach is the large Yoga Centre, a versatile space for yoga, meditation, meetings, and any other events.

Make use of the resort’s fully equipped dive centre—with a qualified dive instructor, kayaks and snorkelling equipment to explore the surrounding and nearby reefs.  

The area has prolific fish and invertebrate life—in the shallower waters, you can expect to see many coral species as well as parrotfish, pipefish, butterflyfish, snapper, grouper and lots of colourful sea anemones with their resident clown-fish. 

While diving, you may see shark species such as black-tip and tiger sharks, as well as eagle and manta rays, giant stingrays, octopus, seahorses, frogfish, scorpionfish, ribbon eels, ornate ghost pipefish, schools of barracuda, rainbow runners, tuna, trevally, Spanish mackerel—the list is almost endless.

Alternatively, take a multi-day sea safari on the custom-designed live-aboard Burmese-style junk, the MV Sea Gipsy, ideal for diving, snorkelling, adventure excursions and romantic overnight trips. The tastefully decorated boat features five comfortable open-air gazebo areas on the main and upper deck which are transformed into beds with mosquito nets at night, and two bathrooms with toilets and freshwater showers on the main deck.

The huge sundeck invites guests to sunbathe on the wooden deck chairs or sit back under the stars with a glass of wine. Other areas provide space for relaxing either in the sun or shade. 

With the diving and snorkelling gear aboard the boat, explore the world below the surface teeming with iridescent reef fish that glitter like jewels and corals glowing with life. The underwater world invites exploration and promises discovery for those who venture into the depths.

The MV Sea Gipsy cruises between several islands where you can stroll along picturesque beaches, try sea kayaking, swim in crystal-clear turquoise waters, and go snorkelling. You may also meet the local inhabitants, such as the Moken. 

To experience all the resort has to offer, combine a few days in a bungalow with a few days on board the boat. Note that the resort is closed during the monsoon season when the seas can be rough and rain may fall for hours on end.

Boulder Island stands out among the many islands of the Myeik Archipelago—its natural beauty is breathtaking and offers a unique opportunity to connect with nature, while the Boulder Bay Eco Resort ensures your time on the island is comfortable and unforgettable.

Arguably the most well-known island in the archipelago is also one of its largest. Lampi Island, about 20 kilometres (12 mi) from the Myanmar mainland, is around 48 kilometres (30 mi) long and five kilometres (3 mi) wide. The island is home to the National Wildlife and Marine Park which protects over 1,000 species of animals, plants and marine life in the Myeik archipelago and was declared an ASEAN Heritage Park in 2003.

As Myanmar’s only marine national park, it is rich in biodiversity with numerous plant species associated with its vast mangrove forests. Some of its many bird species are classified as threatened, including the plain-pouched hornbill and Wallace hawk eagle.

Among the more unique birds are the white-bellied sea eagle, Nicobar pigeon, crested partridge, red-throated sunbird, brown-winged kingfisher, Pacific reef heron, emerald dove and more. 

Look out for loggerhead and green sea turtles, Sunda pangolin and dugong on and around the island. The region’s diverse range of wildlife also includes the cute spectacled leaf monkey, gibbons, reticulated pythons, monitor lizards, oriental small-clawed otter, lesser mouse-deer, civets, and many more.  Sometimes crab-eating macaques can be seen foraging for crabs on the rocky shores.

Many globally threatened species are amongst its amphibians, reptiles, sea turtles, mammals, fish, crabs, sea snails and sea slugs, bivalve molluscs, sea cucumbers, seaweed, seagrasses, and 333 species of plankton.

Activities here include canoeing on the two perennial rivers on the west side of the island where the best-conserved mangrove forests are to be found, and hiking in the jungle. While official hiking trails throughout the archipelago are still very limited, if you are adventurous enough to take on the dense forests, you will find hiking through jungles on the islands to be one of the most rewarding experiences in the region. 

Visit the traditional Moken villages with houses built on stilts, and join them for diving and snorkelling in the Andaman Sea.

Across a 220 metre-wide (722 ft) channel known as Salet Galet cove at the westernmost tip of Lampi Island is Wa Ale Island. The protective cove is a popular anchorage for fishing boats in the fairly shallow waters, particularly during turbulent weather. A tiny island in the cove is home to a small community of tanaka-painted Moken people.

Wa Ale Island is known for its pristine kilometre-long dazzling white-sand beaches, flanked by rocky cliffs and backed by lush evergreen jungle. 

The island’s only accommodation is the luxurious Wa Ale Island Resort, creatively constructed with local materials including river stones and reclaimed wood to minimise its impact on the surrounding environment. 

Its luxury tented and treetop villas overlook the beautiful beaches on its doorstep, while the restaurant serves Asian-Mediterranean cuisine with ingredients from the resort’s organic garden and seafood from local fishermen who use sustainable fishing methods.

As well as relaxing on the white-sand beaches, recreational activities include snorkelling and scuba diving, hiking through the dense jungle, paddle boarding and kayaking through the inlets of the dense mangroves forests. Kayaking and paddle boarding offer great opportunities to move slowly across the shallows that skirt the enchanted mangrove forests and up the small rivers, while getting a glimpse of the many small creatures living in these shallow protected waters.

One of the gateways to the Myeik Archipelago is Kawthaung, Myanmar’s southernmost town, separated from Thailand’s Ranong Province by a broad estuary of the Pakchan River. Known as Victoria Point during the British rule of Burma between 1824 and 1948, it is a charming, laid-back town straddling the hills between the Kra Buri River and the Andaman Sea.

Several points of interest include the 21-metre-high (69 ft) Pyi Daw Aye Pagoda on a hill overlooking the town. Built in 1949, the temple features eight meditation niches representing the eight days of the Buddhist week, and 14 Buddha images. About three kilometres (2 mi) further north is the Mey Paw Kyan Pagoda. 

Explore the large area of stilted houses along the edge of the river at the northern end of town with a few restaurants and drinking spots. At low tide, the residents scour the muddy riverbed for molluscs and crabs, while at high tide the kids run along the wobbly planks connecting the houses and then jump into the water to play like fish. The people are very welcoming and curious to engage with visitors.

The downtown area has a few small restaurants serving authentic Burmese food, as well as coffee shops and interesting markets. At the southern tip is the Nagayone Temple right at the water’s edge. Nearby is the Kawthaung Grand Spirit Shrine.

Before or after your island adventure, stay a few days at the lovely Victoria Cliff Hotel and Resort, located on the cliffs just 6.5 kilometres (4 mi) from Kawthaung harbour. The resort’s luxury accommodation includes Ocean View Wings, Lake View Villas, and Hillside Villas, many of which are brand new with exceptionally beautiful interiors and open sea views.

The resort grounds are well-groomed botanical gardens, complete with a lake, swans, various flowering plants, very tall palm trees and incredibly well-maintained giant bonsais. 

After a day spent enjoying the resort’s facilities or exploring the southern tip of Myanmar, visit the resort’s Maliwan Spa for a relaxing massage or scrub, or work out at the well-equipped fitness centre overlooking the pool and gardens. Enjoy this large swimming pool set among the gardens or the smaller infinity pool overlooking the sea. The resort can accommodate up to 500 guests for weddings, conferences and celebrations.

At dusk, relax in the large open-air restaurant with stunning views over the sea and nearby islands while you enjoy top class Burmese, Asian, and Western cuisines, paired with wines, beer or cocktails. 

As vibrant sunsets give way to glittering moonlight, you will be astounded by the star-strewn skies at night. The restaurant’s prime location promises to make memories as vivid as the surroundings. Pure bliss!

As our journey through the Myeik Archipelago comes to an end, we leave the untouched beauty of its islands with a sense of awe. 

The pristine beaches, dense jungles, and vibrant underwater life have shown us a world that remains largely unexplored, while the warmth of the Burmese villagers and the Moken people have added a human touch to our tropical paradise adventure. 

However, the challenges facing this archipelago remind us of our responsibility to protect these natural wonders for future generations. 

As we bid farewell, we carry not just memories of scenic beauty, but also a renewed commitment to preserving such magnificent corners of our planet. 

Whether you’re an adventurer at heart or simply a lover of nature, the Myeik Archipelago awaits your discovery. So come, explore, and help to keep this paradise unspoiled.
