Not a snorkel site - Limited - pinnacle tops can be snorkeled from the boat in calm conditions, but the site is primarily a scuba dive due to depth and offshore live-boat entry

Active fishing traps/lines on the pinnacle, current shifts around the rock tops, open-water boat entry/exit, reduced viz and swell in monsoon months
