Two nearby sites. Two very different dives.
Blueberry Hill offers a relaxed coral-and-rock route, while the T11 is a roughly 30-metre patrol-boat wreck resting around 16 metres. Together they show the variety of Koh Chang’s local sites.
A compact reef worth diving slowly.
Staghorn and vase-shaped forms
Coral structure gives the shallow site much of its character and creates shelter for reef life.
Groupers and hidden life
Rocky sections reward divers who pause and look into ledges rather than swimming past them.
Turtles and barracuda
Both have been seen here, but wildlife remains unpredictable and should never be promised.
A smaller wreck with an unusual broken profile.
The former patrol gunboat was sunk near Koh Chang in 2013. It is about 30 metres long, lies around 16 metres and is no longer completely intact.
Choose by experience and interest—not by size.
Blueberry Hill may suit a diver who wants light, coral and a relaxed pace. T11 adds structure, history and wreck orientation at a moderate depth.
Neither site needs to compete with HTMS Chang. A smaller wreck or shallower reef can be the more enjoyable choice when recent experience, conditions or the rest of the group point that way.
Before asking for Blueberry Hill or T11.
Can both sites be dived on the same day?
They are close enough to make combinations possible, but the actual route depends on the operator schedule, group and conditions.
Is T11 a penetration wreck?
Treat any overhead area conservatively. The page describes the wreck as a dive site, not permission to enter it without appropriate training and a guide-approved plan.
Is Blueberry Hill suitable for newer divers?
Its shallower character can be suitable, but conditions and the planned route still determine the fit.
Tell me whether you prefer coral, wrecks or a mix.
I can help match that preference to a realistic local dive day rather than promising one named site in advance.
