Have a swim around the water front of Hilton Hotel, water not clear and be aware of the rocks below.
However, a good relaxing time resting on the comfort of beach bench and umbrella. Can also take a ride on horse.
Found a nice Guan Yin temple at ChomKluen area, with its wooden stilts-supported house along the beach. Nice place to sit, relax and have food/drink overlooking the great seaside.
