Best handled with a local operator for park access, boat logistics, and reef routing.
Beacon Reef is a guided boat dive on the east side of Similan Island 8 with an easy sloping reef, hard-coral sections, and standout gorgonian growth. It is a good fit for calm-season reef diving, night dives, and patient macro work when the park is open. The reef’s moorings and simple slope make it an easy Similan check dive to plan around in season.

Depth range, seasonality, and planning context.
Reported Depth
5m - 35m
Depth Note
The profile starts on a shallow slope, then continues across deeper reef sections along the east side of Island 8.
Best Season
November through April, when the park is open and sea conditions are usually calmer.
Typical Conditions
Gentle fringing reef with hard coral, a relaxed slope, and conditions that suit daytime or night dives when calm.
Hazards, restrictions, and access requirements.
Safety Notes
Plan depth and gas management for dives extending beyond 35 m, and account for mild to moderate current.
Access Restrictions
The Similan National Park closes during the monsoon season, so access is seasonal and operator-led when the park is open.
Legal Notes
Plan only within the park's open season and follow marine-park and boat operator rules.
Community notes to help plan your visit.
Scuba Diving
Sloping reef dive with an additional wreck feature; depth range supports both shallow and deeper profiles.
Freediving
Only a secondary fit for freediving; the reef is mainly a scuba site and should be done with park permission and local guidance.
Snorkeling
Possible on calm days when the park is open, but the site is primarily a scuba reef rather than a snorkel-first stop.
