Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Snapper Alley offers some of Similan Islands's richest diving. Water ranges 29-31°C, warmest April, May, June.
Snapper Alley is a good spot for a relaxed dive in the Similans, particularly if you're looking for macro life. We often find juvenile reef fish sheltering amongst the coral bommies. It's a fairly shallow site, making it a nice choice for newer divers or those who prefer longer bottom times to really explore the nooks and crannies. You won't find huge pelagics here, but the smaller critters make it worthwhile.
