Koh Rin is one of Pattaya’s best dive sites and features underwater canyons and swim-throughs. The site has excellent visibility and some splendid coral. Most people approach the site as a day trip from Pattaya. Marine life includes moray eels, squirrelfish and lionfish. This is a shallow dive but probably best left to Intermediate level divers (although it is a great site for snorkeling).
