Scuba Diving Sumatra

Explore some of Indonesia’s best kept secrets, pristine reef diving, wall and wreck diving.


Sumatra is one of Indonesia large island and the sixth largest island in the world. Wild and rugged, Sumatra is blend of Mother Nature extremes, blessed with natural wealth as well as proneness to natural disasters. Volcano eruptions, earthquakes, tsunami, and landslides are common headline grabbers of this one of the world’s richest ecosystem. But nobody can deny Sumatra’s beauty from the top of majestic volcanoes to the lush of the jungles and down at sea level, where idyllic deserted beaches are scattered along the island


Sumatra is more renowned for its tigers and orangutans, its volcanic lakes, and high mountain treks, and is relatively unknown as a diving destination. Its west coast faces the Indian Ocean, making for a slightly different distribution of species than elsewhere. The Indian Ocean also brings rough conditions, so the best diving is found in the shelter of smaller islands such as Pulau Weh on the northwestern coast. Bintan Island is easy access from Singapore so it is a good weekend diving destination.


Pulau Weh – Bandah Aceh

Bandah Aceh is located at the northern tip of the island of Sumatra and the main point of access to Palau Weh Island. It is the northern most point of the Indonesian archipelago. Pulau Weh offers world class diving due to it’s location of where the Andaman Sea meets the Indian Ocean. This remote paradise and new frontier is visited by few divers and is off the beaten path. The Indonesian Government has helped preserve Pulau Weh by declaring two areas a marine park, Pulau Weh Marine Park and Iboih Marine Park.

Tsunami – While northern parts of the island suffered tsunami damaged in 2004 most of the dive sites were spared and are fully intact with damage being reported only on the shallower reefs.

Bintan Island – Riau Archipelago

Bintan in the Riau archipelago can be reached by ferry from Singapore making it a popular weekend dive getaway. The diving is decent, if not as world class as other Indonesian destinations. The Riau archipelago, actually consists of around 3,000 islands, Bintan is the largest and the one with the dive resorts. There are many dive sites, most of them fringing reefs. The visibility isn’t that good due to the proximity to the Malacca Straits, one of the world’s busiest shipping channels. Visibility can be 20m but is often just 5m. However coral is healthy and there are plenty of reef fish and macro critters. Also, there are several ship wrecks in the area to be explored.

Other Interest – The world famous crater lake of Danau (Lake) Toba is the third biggest tourist destination of Indonesia. The island in the huge lake, Pulau Samosir, attracts many tourists. Lake Toba is the largest lake in Southeast Asia, once created by an enormous eruption less than 100.000 years ago. The eruption was approximately 8.000 times more powerful than the eruption of Mount St. Helen in 1981. Ashes in the stratosphere circled around the earth for years and changed the climate. As things began to settle another volcanic eruption happened about 25.000 years later and built up a secondary volcano inside the caldera. The cone of that volcano collapsed and formed the island Samosir while the crater of the first eruption filled with water, what to become Danau Toba.
