Siaba Besar is a sheltered bay in central Komodo used as much for its calm as for its marine life. It is a frequent choice for the first dive of a trip, when guests are reassembling gear and getting used to the water again.
A check dive worth doing
Protected from the main channel currents, Siaba offers a gentle sandy slope and coral bommies at easy depth. The lack of current makes it useful for buoyancy checks, camera setup and weight adjustment before the harder northern sites.
What you see
Green turtles in unusual numbers, often several on a single dive, resting on the sand or grazing. Garden eels, cuttlefish, batfish and a healthy population of reef fish. Macro subjects reward slow divers.
Experience level
Suitable for all certified divers, including recently qualified ones, and good for snorkellers.
Conditions
Water temperature in central and north Komodo runs 26–30°C, generally warm and calm. A 3mm long wetsuit is the most versatile choice; bring a 5mm or a neoprene hoodie if you feel the cold. The Komodo season is June to September, departing from Labuan Bajo. Open Water divers are limited to a maximum depth of 18m by law and insurance.

Salah writes for Teman Liveaboard, the owner-operator of the KLM Teman. The Teman is a 36-metre Indonesian phinisi, handbuilt in Sulawesi and launched in 2017, carrying 12 guests in 5 ensuite cabins with a permanent crew of 10 and a Cruise Director. The team behind her has more than 20 years sailing the Indonesian archipelago. The boat works Komodo National Park from June to September out of Labuan Bajo, Raja Ampat from November to April out of Sorong, and runs Banda Sea and Ring of Fire crossings between the two seasons. The dive site guides on this blog are written from the operator's own logs and itineraries, with conditions, seasons and equipment guidance checked against the dive team who work these sites every week. Where a detail depends on the day — depth on a given tide, or where a current will take you — we say so rather than guess, because that is a briefing the Cruise Director gives on the boat, not something a web page can promise.
