Banyak Island (Kepulauan Banyak) is a hidden tropical paradise located off the west coast of Sumatra, Indonesia, in the Aceh Singkil Regency, Aceh Province.
Banyak Island (Kepulauan Banyak) is a remote archipelago consisting of around 99 small islands, known for its pristine beaches, crystal-clear turquoise waters, and incredible marine biodiversity. The name “Banyak” means “many” in Indonesian, reflecting the large number of islands in the group.
It’s a dream destination for travelers seeking tranquility, unspoiled nature, and world-class surf. Several islands, such as Pulau Bangkaru and Pulau Tuangku, are popular among surfers and divers due to their rich coral reefs and consistent waves. Bangkaru is also a protected turtle nesting site, where green turtles come ashore to lay eggs.
Despite its beauty, the Banyak Islands remain largely untouched by mass tourism, offering a peaceful retreat for adventurous travelers. Access is typically via boat from Singkil, and accommodations range from rustic bungalows to eco-lodges, emphasizing sustainability and harmony with nature.
What to do in Banyak island :

Snorkeling
There is shallow water and corals everywhere! Bring your own gear or rent it in the villages. You can see a lot of different sea life. At Sikandang you can even see whales and dolphins. Near Rago Rago you can see Dugongs (Sea cow) if you are lucky because they don’t like disturbance. Also turtles, manta rays and much more species are available.
Kayaking
If you are an experienced kayaker you can go alone, but if you are new to kayaking, you should be accompanied by a guide. Costs more, but is worth the risk. Some tourist already disappeared because of missing experience.
Island Hopping
Many of the lonely islands are close to each other and many nice beaches are available. In one day you can visit several islands, either by kayak, or you charter a local boat and let you drop off on the islands you like.
Camping
You can camp on most islands. Best is Asok, because there are no mosquitos and also a small hut with shower is available. But also the very small islands are mosquito free and great locations for camping.

Surfing
The islands are scattered with numerous coral reefs that are habitat to a diverse range of species including green and leatherback sea turtles, a variety of fish, octopus and lobster species, as well as other sea life. Although, the region has recently experienced some challenges with illegal hunting and environmental hazards, that are affecting its precious ecosystem.
Like other islands in the region, the Banyak Islands are perfectly situated to receive constant swell from the Southern Indian Ocean, waves come to the island’s shores with perfect form and consistency. Glassy conditions are produced by light winds and big waves are produced by large ground swell.
Jungle trekking
The big island on the middle is great for jungle trekking. You should start in Haloban, where you can find guides and equipment (as of equipment – not even machette needed if you can handle couple of scratches from the abundant vegetation). You can climb up the 260m high mountain, which takes around 3 hours. You can also visit the crocodile river with a guide. Furthermore, you can combine trekking with kayaking, start with the kayak, go up a river and do a 1-2 hours trek to a very long white beach. Also many caves and waterfalls available.
Fishing
It is possible to go fishing with locals. Simply ask around and you are likely to find a fisher who takes you on his fishing trip.
Relaxing
With its lonely white beaches and fantastic scenery, the Banyak islands are a great place for just relaxing and sunbathing.
