Snapper Alley Green Turtle

Snapper Alley is located on the south east of Similan Island number nine. The current usually runs from east to west and although usually mild, can sometimes be quite strong.  This makes for an exhilarating drift dive - gliding over the reef observing the marine life, stopping for a closer look where points of interest arise. Glass Fish swarm and cloud the many coral heads and vast areas of staghorn coral, giving rise to menacing packs of assaulting Snappers, which scream down in silvery flashes picking off the hapless victims. It's a great show and very mesmerising, particularly in early morning or late afternoon, when the sun is low and the Snappers are more frenzied in their hunting.

To the east and the west of the dive site are some spectacular granite rock formations, where it's possible to find some Leopard Sharks resting on the sandy bottom. Whitetip and Blacktip Sharks are also frequently spotted around these areas, as are huge Napoleon Wrasse. Other treats to search for include Ghost Pipefish, Frogfish and even the occasional Seahorse camouflaged in a Gorgonian Fan.

Unfortunately, Snapper Alley suffered more than its fair share of tsunami damage and there is evidence of quite severe coral damage in places. That's not to say this isn't a nice dive and on a good day it can be awesome.
