Planning a trip

8–12 days

worth going for

Long haul, usually two flights.

10,047km from Singapore — about 24h each way, so two of those days are travel. 7 dive sites within 25km.

When people dive it

Busiest May, Jun, Sep · almost nobody dives it Jan, Nov, Dec.

From 333 logged sightings — when divers are in the water, which is not quite the same as when visibility is best.

Dive Crew is a dive group from Singapore. Members plan trips here, log their dives, and share their photos of each site.

Moon and tides

Waning gibbous

71% lit · day 20 of the lunar month

Neap tides

Neap tides — the smallest range of the month, so the weakest currents. Easy conditions and usually the clearest water, though a drift site may barely drift.

New 10 Oct Full 26 Oct

Phase computed here, not fetched. This is the spring/neap cycle, which sets how hard the water moves — not a tide table: no free source publishes high and low water for Southeast Asian reefs, and the range peaks a day or two after the moon does, by an amount that varies with the coast. For times on the day, ask the operator.

Getting there

Transferthe jetty~6h 45mRoad transfer to the coast, usually arranged by the resort or liveaboard.Directions →
Ferrythe crossing~2hAt this distance the last stretch is a scheduled crossing rather than a dive boat, so book it before the flight — a missed sailing usually costs a day. Which crossing it is has been worked out from the distance and not from a timetable; ask the operator.

📍 Trolla on Google Maps 🧭 Route from Bergen

Times marked ~ are estimated from straight-line distance and will be roughly right at best. The road legs are the ones Google Maps answers properly; it will not plan the ferry or the dive boat at all. A dive site's coordinates put a pin in open water, so the map link drops you on the site, not on a jetty.
