Pulau Weh is a small active volcanic island off the northern tip of Sumatra, the northwesternmost point of Indonesia ('Kilometre Zero'), where the Andaman Sea meets the Indian Ocean. Deep, current-fed water sustains exceptional fish density on volcanic pinnacles, a deep WWII-era German wreck, and bubbling underwater volcanic vents, all within minutes of the dive-village beaches at Iboih and Gapang.

Description
Pulau Weh (also called Sabang or Weh Island) is a 122 km² stratovolcano of the Sunda Arc that separated from mainland Sumatra after a Pleistocene eruption, sitting roughly 15 km off the island's northern tip in the Andaman Sea. It marks 'Kilometre Zero' — Indonesia's northernmost road-connected point — and most diving clusters around tiny Rubiah and Seulako islands off Iboih village on the western tip, with a few exposed pinnacles and a deep wreck reached by short boat hops. Because the island sits where the Andaman Sea meets the Indian Ocean and away from any river run-off, visibility is typically 20 m and often exceeds 30 m, with water a warm 28–29 °C (occasional cold upwellings drop it sharply). Volcanic geology defines the diving: granite boulders, walls and canyons, plus genuine hydrothermal features where hot bubbles rise from sandy vents. Currents range from gentle in the Rubiah gardens to strong and downward-pulling at exposed sites like Arus Balee, Batee Tokong and Pantee Peunateung, so site choice spans true beginner to technical. The signature site, the 134 m steamship Sophie Rickmers, lies at 37–55 m and is a decompression dive for experienced or technical divers only. Big schools of jacks, barracuda and trevally are reliable; devil rays, mantas and the occasional whale shark or mola appear seasonally.
Highlights
What makes this dive worth the trip.
Pulau Weh sits where the Andaman Sea meets the Indian Ocean off Sumatra's northern tip, away from any river run-off, so visibility averages 20+ m and often exceeds 30 m, with warm 28–29 °C water year-round; the deep, current-fed water sustains an unusually high quantity and variety of marine life for a shore-based destination.
The island is an active volcanic stratovolcano of the Sunda Arc, and that geology shows up underwater: granite boulders, walls and canyons, plus genuine hydrothermal vents where streams of hot bubbles rise from a sandy bottom at the 'Underwater Volcano'/Hot Springs site — a feature divers can hold a hand over to feel the warmth.
The Sophie Rickmers, a 134 m German cargo steamship built in 1920, was scuttled in Pria Laot Bay in May 1940 — her crew quietly opened the sea valves while a Dutch boarding party was distracted, denying the seized ship to the Allies. She now rests at 37–55 m and is a decompression dive for very experienced or technical divers only.

Batee Tokong
A pinnacle off the northern tip of Seulako Island and one of Pulau Weh's signature sites, prized for dramatic volcanic topography and high fish density. The rock drops from near the surface to around 22 m before sloping past 40 m, its flanks carpeted in large gorgonian sea fans and riddled with crevices that hold a famous abundance of moray eels. Currents can be tricky, often drifting one direction and sometimes requiring divers to hold the rock for a safety stop; strong circular flow draws in pelagics. Late afternoon can bring schools of 30+ devil rays alongside whitetip and blacktip reef sharks, barracuda, big tuna, eagle rays and hunting trevally.

Pantee Peunateung (The Garden)
A crescent-shaped deep wall off the western coast where vertical drop-offs begin around 25 m and plunge well past 40 m, with the bottom beyond recreational limits (sources cite ~70 m). The site is known for powerful currents — frequently sweeping downward — and for a resident school of bigeye trevally that can number in the thousands, circling alongside barracuda, fusiliers, tuna and giant sweetlips. Hammerhead sharks are an occasional deep sighting. An advanced site demanding good buoyancy and respect for the down-current; not for inexperienced divers.

The Canyon
Off the northern tip of Weh Island near Seulako, The Canyon (also called Pantee Aneuk Seuke) is all about topography: a large weathered granite boulder split by deep crevices you can swim through, plus a descending wall and a natural arch, with the seafloor draped in hundreds of giant gorgonian sea fans. Beyond the dense reef fish — bannerfish, unicornfish, barracuda, trevally, snapper and emperors — the site is a place where cold deep-water upwellings occasionally bring eagle rays, devil rays, mantas, turtles, Napoleon wrasse and even mola mola. A must-see volcanic landscape dive.

Seulako Drift
A gradually sloping rocky reef off Seulako Island dived as a relaxed-to-moderate drift — often described as 'flying' along the reef and, in the right conditions, a full circuit of the island. Hard corals, soft elephant-ear corals and anemones cover the slope, home to resident reef sharks, moray eels, spotted stingrays, giant grouper, sweetlips and Christmas-tree worms. Its standout feature is groups of devil rays, sometimes 20 or more, that pass through; fusiliers, trevally and tuna stream by in the current. Manageable for divers comfortable with drift conditions.

Arus Balee
Set in the channel between Seulako and Rubiah islands, Arus Balee ('widow's current') is widely called the fishiest dive on Pulau Weh — a 'fish soup' of fusiliers, hunting bluefin and giant trevally, black snappers, coral breams and giant sweetlips, with ribbon eels and reef sharks. As the name warns, it carries strong currents with a notorious downward pull where the channel narrows, so it is run only when conditions allow and best left to divers experienced with current. A deep channel borders it to the south and a shallow channel to the north.

Sophie Rickmers Wreck
Pulau Weh's signature wreck and one of Indonesia's great deep wrecks: a 134 m German cargo steamship built in 1920 and scuttled in Pria Laot Bay in May 1940 (her crew opened the sea valves while distracting a Dutch boarding party). She sits upright in roughly 55 m of water with the wheelhouse around 37 m and the deeper structure to ~55 m and beyond. A staged-decompression dive for very experienced or technical divers only, with short bottom times and significant deco. The intact hull hosts giant groupers, giant moray eels, jacks and the normally deep-dwelling black-spot angelfish; plankton-rich water occasionally brings mantas and whale sharks past the wreck.

Rubiah Sea Garden
The most relaxed site on Pulau Weh, in the sheltered, clear water around Rubiah Island just off Iboih beach — famous shallow coral gardens over white sand and dramatic black granite, sloping into soft-coral gardens. With gentle currents and easy depths it is the island's classic beginner, training and snorkelling site. Macro and reef life is the draw: honeycomb, black-spotted and black-blotched moray eels, nudibranchs, flatworms, bubble anemones, giant clams, stingrays, ghost pipefish, leaf scorpionfish, cleaner wrasse and turtles. A good first dive of a trip and a fine afternoon shore or snorkel option.

Shark Plateau
A plateau around 24 m deep just north of Batee Tokong, often combined with it on the same dive. The deeper, current-swept setting reliably gathers reef sharks — black-tip and white-tip, with occasional grey reef sharks — over a bottom of sea fans, barrel sponges and hard corals, joined by schooling bigeye trevally, tuna, fusiliers, eagle rays and the occasional manta. Deep water and strong currents make it an advanced site; Nitrox is recommended to extend bottom time at depth.
