If you are want to explore Sumatra underwater, here are the list of absolute best locations for snorkeling in Sumatra:
1. Pulau Weh, Aceh
Pulau Weh is one of the best snorkeling destinations in Sumatra, renowned for the clarity of its seawater. Additionally, its pristine underwater ecosystem is a major draw.
Located at the western tip of Indonesia, specifically in the small village of Iboih, the island boasts a unique marine environment. This is because Weh lies at the convergence of the Indian Ocean and Andaman Sea currents. This creates a high level of marine biodiversity.
Water visibility at certain spots can reach 15–30 meters during the dry season. This certainly makes snorkeling an ideal activity. In terms of access, Weh Island can be reached via land travel and a ferry from Banda Aceh to Balohan Port.
Tourism infrastructure is quite well-developed, with a wide range of accommodations from simple homestays to beachfront resorts. In addition to snorkeling, visitors can also enjoy white-sand beaches, diving, and local seafood cuisine.
Supporting facilities such as snorkeling equipment rentals, boat trips, and local guides are available in nearly all major tourist areas. These conditions make Weh Island suitable for both beginners and experienced snorkelers—especially those seeking natural, less commercialized spots.
See Also:
– Rubiah Island
Rubiah Island is famous as a “natural aquarium” on Weh Island thanks to its crystal-clear waters and rich coral reefs. It is located very close to Iboih Beach, so visitors can reach it by small boat in just 5–10 minutes.
The snorkeling area is relatively shallow with calm currents, making it very safe for beginners and families with young children. Rubiah’s underwater beauty stands out with its well-preserved combination of hard and soft coral reefs.
Visitors can spot tropical fish such as parrotfish, clownfish, and various small, brightly colored species. At certain points, the water is so clear that it feels like swimming in a giant natural aquarium.
In terms of facilities, snorkeling gear, life jackets, and tour boats operated by the local community are available for rent. There is also a simple rest area around the island. However, facilities on Rubiah Island are still relatively basic and not very comprehensive. Travelers are advised to bring personal essentials such as drinking water and sunscreen.
See Also:
– Karang Batik
In addition to Rubiah Island, Karang Batik is also one of the best snorkeling spots in Sumatra. However, it is more secluded and remains very pristine on Weh Island. Unlike the busier Rubiah, Karang Batik offers a much quieter atmosphere with relatively few visitors.
This makes it an ideal choice for travelers seeking a private snorkeling experience close to nature. Karang Batik’s uniqueness lies in its coral reef formations, which remain largely untouched and in their natural state.
The diverse coral structures provide habitats for a wide variety of small fish and marine life—species rarely found in crowded tourist areas. Currents can be slightly stronger at certain points, so snorkelers typically need basic experience or use a life jacket.
In terms of access, Karang Batik is typically reached by boat from Iboih Beach, with a travel time of about 10–20 minutes. Facilities at this location are quite minimal. This means tourists still need to hire a local guide for safety and to navigate to the best spots.
Tips & Note: based on our experience, the other snorkeling spots in front of Rubiah or east part of the island, Pulau Seulako spot etc, the current a bit strong. Using the long fins are recommended. If you are travel to Aceh and snorkeling, modest swimwear are highly recommend when on public beaches.
2. Banyak Islands, Aceh
Banyak Islands is one of Sumatra’s hidden paradises. It is located in the Aceh Singkil region. This archipelago consists of dozens of small islands with white sand beaches and crystal-clear blue waters. It is perfect for snorkeling, island hopping, or simply enjoying the tropical tranquility.
The waters are relatively calm because they’re sheltered by the small islands. This means underwater visibility is often excellent, especially during the dry season. The underwater beauty stands out thanks to super-healthy coral reefs, a variety of tropical fish, and several shallow spots for beginners.
Additionally, the beaches feature fine white sand with a gradient of turquoise-blue seawater that is incredibly photogenic. To reach the Banyak Islands, visitors can travel by land from Medan or Banda Aceh to Singkil. From there, the journey continues by motorboat to the main islands, such as Balai and Tuangku.

The journey is indeed quite long, but there’s no need to worry—it’s well worth the beauty along the way. It’s worth noting that tourist facilities in the Banyak Islands are still basic. Accommodations are typically homestays owned by local residents, with limited electricity. Boat rentals, snorkeling gear, and local guides are available but must be booked in advance. However, with a quality package, all the comforts are ready to be enjoyed.

3. Pahawang Island, Lampung
From Aceh, we move on to Lampung. Here lies Pahawang Island, popular for its shallow snorkeling and iconic underwater photo spots. The island is divided into Pahawang Besar and Pahawang Kecil.
It is located in Pesawaran Regency and is about a 2–3-hour drive from Bandar Lampung City. The rest of the journey takes about 30–60 minutes by boat, depending on the departure point.
The most recommended spot is the “Underwater Garden” area, which is filled with both artificial and natural coral reefs. These create a unique underwater landscape perfect for photography. Additionally, tropical fish like clownfish and damselfish swim through the shallow waters, making it an ideal spot for beginner snorkelers and families alike.

Another highlight of Pahawang is its seawater, which features shades of blue-green with stable visibility during certain seasons. The beach also boasts soft white sand and a tranquil tropical atmosphere, perfect for relaxing after snorkeling.

4. Mandeh Island, West Sumatra
The Mandeh Tourism Area is also one of Sumatra’s premier marine destinations. In fact, this area is often dubbed the “mini Raja Ampat.” This is due to its landscape, which consists of clusters of small islands, calm bays, and stunning turquoise waters.
It is located in South Pesisir Regency, about a 1.5–2-hour drive from the city of Padang. From there, visitors continue by boat to explore the small islands within Mandeh Bay.
Mandeh’s main attraction lies in the combination of the marine landscape and the green hills surrounding the bay. The sea water in this area is relatively calm because it is sheltered by the island clusters. Not only is it ideal for kayaking, but it’s also a top activity here. Water visibility is quite good during the dry season, allowing visitors to clearly see shallow coral reefs and small fish at several key snorkeling spots.
In addition to the underwater beauty, the panoramic views from the hills surrounding Mandeh Islands are equally enchanting. From the heights, visitors can see a scattering of small islands dotting the blue ocean. This creates a highly photogenic scene and is often a favorite spot for landscape photography.

5. Mentawai Island, West Sumatra
The Mentawai Islands are also globally renowned as one of the world’s premier surfing paradises. Yet behind their reputation for massive waves, this region actually harbors pristine, untouched natural snorkeling spots.
Located quite far from the main island of Sumatra, access to the Mentawais typically starts from the city of Padang. The journey involves taking a speedboat to Siberut Island or the surrounding islands. Although the journey is long and tiring, the breathtaking scenery upon arrival is well worth the effort.
The most fascinating aspect of snorkeling in Mentawai Islands is the natural environment, which remains largely untouched by human hands. The water offers excellent visibility at certain points. However, currents in some areas can be quite strong, making these spots more suitable for experienced snorkelers or those under the supervision of a guide.

Sikuai Island is one of the great places for snorkeling in Sumatra that is relatively easy to reach from the city of Padang. It is only about a 30–45-minute boat ride from Bungus Harbor. The island is known for its peaceful atmosphere, white-sand beaches, and crystal-clear waters. It is ideal for leisurely snorkeling.
Its calm waters with consistent visibility are a major draw, especially near the shore. The coral reefs around the island are still in fairly good condition. Plus, small fish are often spotted in the shallow waters. This makes Sikuai perfect for beginners looking to try snorkeling without challenging currents.
The island also boasts an attractive landscape. There are small hills that visitors can climb to enjoy panoramic ocean views from above. From the summit, travelers can witness the gradient of blue-green ocean hues surrounding the small island of Sikuai.

7. Soreh Island, Bintan
Next up is Soreh Island, one of the hidden gems in the Bintan area. The area offers a more private and peaceful snorkeling experience. Visitors can reach the island by boat from Bintan.
The most prominent attraction is its natural environment, which remains largely untouched. The seawater tends to be clear with minimal human-generated waste, ensuring that marine life remains well-preserved. Snorkeling here offers a more personal experience, allowing travelers to enjoy the ocean’s ambiance without crowds.
The coral reefs around the island are very natural, although not as dense as those in major destinations like Weh Island or Mentawai. However, tranquility and privacy are the main draws of this destination.
Given the limited facilities, travelers typically rely on local tour operators or independent boat trips. This means that logistical preparation and personal supplies are essential before visiting.

If you’re in the westernmost part of Sumatra, the Natuna Islands are the best option for those who want to go snorkeling in Sumatra. This region offers the most extensive and still very pristine marine area in western Indonesia. Located in the North Natuna Sea, the area is characterized by crystal-clear blue waters and an incredibly rich marine ecosystem.
What visitors most often seek in Natuna is the sea’s condition, which remains virtually pollution-free. Because the region is vast, each small island in Natuna has distinct underwater characteristics.
Access to Natuna is typically via flights from Batam or Jakarta to Ranai, the capital of Natuna Regency. From there, the journey continues by boat to the surrounding small islands.

9. Lengkuas Island, Belitung
Marine tourism combined with learning about history can certainly provide an unforgettable experience. One such destination is Lengkuas Island. Lengkuas Island is one of Belitung’s iconic marine tourism sites, famous for its old colonial-era lighthouse.
The 57-meter-tall lighthouse, with 18 floors, was built by the Dutch colonial government in 1882. Interestingly, it remains fully operational to this day, primarily to assist with maritime navigation.
Lengkuas Island offers a combination of crystal-clear blue ocean views and Belitung’s distinctive granite rock formations. These are scattered throughout the surrounding waters. Snorkeling here is very easy due to the relatively shallow depths.
In fact, at some spots, even adult-sized tourists can stand or walk on the seabed. Additionally, water visibility is exceptionally high, especially during sunny days.
The coral reefs around the island are also still fairly well-preserved. Small fish are often seen around the underwater granite rocks. In addition to snorkeling, visitors can also climb the lighthouse to enjoy a 360-degree view of the Belitung area.
Visitors can reach the location in about 30–40 minutes by boat from Tanjung Kelayang Beach. Fishermen’s boats (chartered) typically accommodate 5–10 people without feeling cramped. The cost ranges from Rp400,000 to Rp500,000 per group.

10. Batu Berlayar Island, Belitung
Last but certainly not least is Batu Berlayar Island in the village of Tanjung Binga-Tanjung Kelayang, Sijuk District, Belitung. This is a unique destination famous for its massive granite rock formations. The rocks stand like ship sails in the middle of the sea. It is located not far from Lengkuas Island and is typically visited as part of an island-hopping tour in Belitung.
Its main attraction is, of course, its highly photogenic visual landscape. The massive granite boulders emerging above the water’s surface create a dramatic scene, especially during low tide or on sunny days.
Snorkeling around Batu Berlayar is fairly easy due to the shallow and relatively calm waters. Visitors can spot small fish and some coral reefs around the rock formations. However, the main focus of this destination is more on the beauty of the landscape than on a complex underwater ecosystem.
That said, tourist facilities on Batu Berlayar Island are quite limited. Therefore, it is recommended to visit as part of a day tour from Belitung with a professional operator like SWI Tour & Travel. This ensures a safer and more comfortable vacation experience.
