One of the most popular at dives at Alton’s is a drift dive along the interesting and varied wall of this site. Airport caves is just around the corner from us, a quick 5-minute boat ride away. The top of the reef at Airport caves is very shallow around 10ft only, which makes it ideal for snorkeling as well as diving. Elkhorn corals are scattered along the top of the wall, which drops off to a maximum depth of around 80ft/24m. As you drift along the wall there is a series of three caves, which can be explored a little including one beautiful swim through called the "horseshoe". We expect to see green moray eels, black and yellow fin grouper, eagle rays swimming along the wall and hawksbill turtles hunting out a meal. We have even seen the occasional Manta here and have regular dolphin encounters in this area.
