The north-east shore of Ko Bangu (Similan 9): a reef from about 8 m, coral heads and a boulder cluster in the shallows, then the sand slope with the big granite boulders at 22–25 m and a single boulder at 18 m, the sand going on past 30 m, on the OpenStreetMap coastline, so positions are approximate. The three trees that name the site stand on the island's edge above the reef; their exact place is not known, so they are not drawn. Boulder depth 22 m from first-hand observation; garden eels on the sand.

On Similan Island 9 (Ko Bangu), at the northern end of the archipelago. The dive has two halves: first the three very large granite boulders that give the site its name, standing at about 22 m, and then the sand beyond them, which slopes off past 30 m.

Dived 24 November 2013 to 27.5 m — the first of three dives at Island 9 that day, with Breakfast Bend and North Point.
