Our full-day trips can take you to these beautiful islands located to the West of Koh Pha-Ngan. With wonderful dive sites full of interesting overhangs and “swim-throughs”, combined with sloping reefs starting at around 2m in depth, these are great sites for both diving and snorkeling. An incredible diversity of both hard and soft corals adorn these reefs, making them the perfect habitat for Banded Sea Snakes (Kraits), Fusiliers, Parrotfish, Wrasse, and various species of Angelfish and Butterflyfish. Explore the nooks and crannies and you’ll also find Moray Eels, Stingrays, Crabs and Shrimps. The main swim-through at Hin Yippon, Angthong Marine Park. This partially submerged cave cuts through the rock, meaning you can enter at one side and exit on the other. Snorkelling Note: Due to its calm, shallow water and abundance of colourful, healthy corals and marine life, Angthong Marine Park offers an ideal location for snorkellers and swimmers..
