| Skill Level: | Beginning to advanced | |
| Depth: | 5 - 30+ | |
| Currents: | Occasion, mild to strong | |
| Topographie: | A sloping island ridge that continues on down into the water to a maximum depth of 30+ meters. Steep wall dive on the southern side of the ridge, rocky outcrops and canyons on the ridge itself, expansive coral gardens and smaller bommies on the northwestern side of the dive-site | |
| Highlights: | This is the only limestone island in Mu Koh Similan National Park, thus the water composition may sometimes be dense with particles and plankton, drawing numerous Manta Rays to the site regularly. Huge sponges and sea fans at depths 30+ meters | |

| How to dive this site: | Drop in and ascend in protected bay area south of the tapering ridge, down to maximum depth heading in a due westerly direction. Zig-zag back up the ridge in an easterly direction. Depending on current, either continue on around the ridge to the east into the coral gardens, or return along the wall back to drop in point | |
| Our tips: | The wall itself is best viewed in the afternoon, as the sun shines brilliantly on the anemones and soft coral gardens |
|
| Photo tip: | Excellent wide-angle photography site. |

"I contacted Thailand Dive and Sail to help me book a day dive trip. Niko met me at my hotel, made suggestions based on my experience and booked me through a local dive organization. I really appreciated Niko's candor and honesty about what to expect diving in Thailand. And although the dives were a little disappointing, I don't regret going. The people at Thailand Dive and Sail are very nice and helpful and I would recommend them to assist in booking any dive or tour."
