This Rocky Point page records the southeast side of Similan Island 1 in Divezone’s original notes. It should not be used to book a routine dive there: local operators describe Islands 1–3 as closed to the public for turtle and reef conservation.
Dive dates appear when the writer supplied them. Earlier stories keep their original words and have no newly assigned ratings.
Which Rocky Point is this?
The historical entry names Island 1. Other Similan descriptions use Rocky Point around the northern islands, including North Point. Those names do not establish that the sites are identical, so this record has not been moved to Island 9.
A glimpse of the original description
The older account describes submerged boulders, sand and hard coral, with deeper terrain and potentially strong current. Its depths and wildlife observations have not been revalidated as a current visitor briefing.
Conservation comes before an itinerary
Similan Seven Sea Club identifies Islands 1–3 as closed for conservation. This page therefore does not recommend access to the Island 1 location. A general Similan park opening is not permission to visit every reef.
Choosing a current Similan trip
The Similan diving guide provides planning context. For the northern site, the separate North Point page avoids mixing two historical records.
Questions about Rocky Point
Can I book the Island 1 Rocky Point from this page?
No current permitted visitor access is confirmed here; Islands 1–3 are described by the operator as closed for conservation.
Is this North Point?
The original record identifies Island 1, whereas North Point is a separate northern Similan site.
Are the old depths a dive plan?
No. They are historical descriptive information, not a verified current profile.
Does the seasonal park opening remove local closures?
No. Site-specific conservation restrictions can remain in place during the wider park’s open season.

Similan Islands
Granite boulder dives, reef photography and northern Andaman liveaboards. Day boats also visit the Similans; route choice, current and park access determine the right trip.
