Remote Koh Tang access and current-led drift timing make a local operator essential.
Fly By is a north Koh Tang drift reef for divers who want current, structure, and a moving reef line rather than a static swim. The route runs over rocky seabed with coral bommies near the shallower edge and more relief farther out. Boat timing matters because the best dive is the one the operator can drop and pick up cleanly. When conditions line up, the reef holds dense fish traffic and a fast-moving, open-water feel.

Depth range, seasonality, and planning context.
Reported Depth
2m - 20m
Depth Note
The reef starts shallow and deepens to about 20m+, with the strongest coral around 12m. Use the deeper outer edge as the conservative limit.
Best Season
November to May is the cleaner dry-season window for Koh Tang; June to October is wetter and should be treated more cautiously.
Typical Conditions
Warm tropical water, strong current at Fly By, and generally good clarity on better days. Expect a drift-oriented boat plan rather than a relaxed shore entry.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Use a guide who knows the site, because the current can run fast and the island is remote. Plan gas reserves, drift timing, and surface pickup conservatively.
Access Restrictions
Boat access only; the island is remote and should be arranged through an operator familiar with Koh Tang.
Legal Notes
Koh Tang has a small military presence, so access should stay within operator-led permissions and local coordination.
Community notes to help plan your visit.
Scuba Diving
This is a guided drift dive. The reef starts shallow, coral is strongest around the mid-water bommies, and the route deepens toward the outer edge, so air and pickup timing matter.
Freediving
Not a good freedive-first site. The current and boat logistics make it better for scuba drift diving than for casual breath-hold visits.
Snorkeling
Snorkeling is not the intended use here. The site is boat-based and current-driven, so the useful terrain sits better in the scuba zone than at the surface.
