Vulcano
A warm, shallow vent dive with bubbles and easy boat access.
Local operator required
The site is normally handled as a guided boat dive from Pulau Weh operators.
Vulcano is a signature Pulau Weh boat dive for curious divers who want a volcanic hot-spring site.
About Vulcano
Vulcano is a short-boat Pulau Weh dive with warm bubbles rising from volcanic cracks and a light sulfur note. It is a shallow, easy site where the appeal is the strange hot-spring feel more than a reef profile. It suits curious divers who want a novelty site rather than a standard reef, and it is best treated as a calm-day operator dive. Look for five-lined snappers, pufferfish, small groupers, and crabs adapted to the warm vent area.
