Stonehenge lies north of Koh Miang, Similan Island 4. Its name suits the scenery: large rock formations create a substantial underwater landscape, with coral and sea fans adding detail between the stone. Depth and current are central to choosing this dive.
Dive dates appear when the writer supplied them. Earlier stories keep their original words and have no newly assigned ratings.
Rocks with a sense of scale
Sanook Scuba describes towering formations rising from around 25 metres and deeper, with soft coral and gorgonian sea fans in the spaces between them. Its broader site profile spans 10–40 metres. The difference matters: the presence of a shallower section does not make every part of the rocky site a shallow dive.
Life around the formations
The same operator describes barrel sponges, lionfish and scorpionfish around the rocks, with angelfish and butterflyfish over the reef. Barracuda, dogtooth tuna and bluefin trevally are among its reported passing fish. The attraction is a combination of large scenery and closer subjects, rather than a guaranteed shark encounter.
Experience and the day’s conditions
Current can be strong. Deeper terrain reduces the scope for a long, unhurried visit, so the actual profile needs to suit the group’s training and recent experience. A site description is useful for choosing the trip; the local briefing determines the dive itself.
A named stop on the programme
Visit Similan Islands lists Stonehenge with West of Eden on its Thursday day-trip programme for the 2026–27 season. This is an example of a scheduled visit, subject to weather and operating decisions. A general Similan booking does not necessarily include the same stops.
For companions
A boat trip to a deeper rocky dive site does not establish a snorkelling programme. Passenger fares, supervised activities and any island stop need to be included in the chosen offer.
Questions about Stonehenge
Is Stonehenge a shallow dive?
Some published profiles include shallower terrain, but much of its rocky character lies deeper. The actual dive profile is more useful than the minimum depth alone.
Are currents always strong?
No, but strong current is a documented possibility. The boat assesses conditions before choosing the dive.
Does a day trip visit Stonehenge?
Some advertised day-trip schedules include it. The actual date and final site choice depend on the operator and conditions.
Is this the Stonehenge near Koh Lipe?
No. This page concerns Stonehenge in the Similan Islands, north of Koh Miang, Island 4.
