Hin Yai Pinnacle
A pinnacle mapped by a Pattaya dive centre in 2012 with the help of fishermen and naval charts; the top is at about 14 m and it slopes to 25–30 m at the sand. Nudibranchs and other macro life, morays, schooling batfish, great barracuda and eagle rays are described, and a second, smaller pinnacle lies nearby.
