Ko Pha-Ngan is fringed with some delightful beaches. For additional seclusion, try the isolated beaches on the east coast, which include Hat Yuan, Hat Thian and teeny-tiny Hat Thong Reng. For a further choice of enchanting beaches, consider doing a day trip to the stunning Ang Thong Marine National Park. Trekking between beaches is another excellent way to explore around the edges of the island, but take a lot of water. Linked by road, west-coast beaches including Hat Yao, Hat Salad and Ao Mae Hat are the place for sunset views over to Ang Thong National Marine Park.
Beyond the beaches, a major highlight of the island is its many waterfalls which glisten throughout the interior. It's likely – though not 100% probable – that waterfalls will run dry between March and June. It does, however, depend on rainfall, which can vary from year to year. The majority of rainfall is from November to December, meaning waterfalls are gushing through winter to January and February. All that said, the string of falls leading to the beach at Than Sadet is pretty much flowing all year round.
Ko Pha-Ngan’s temples provide a tranquil sanctuary and an opportunity for reflection. One of the most intriguing shrines on the island is the colourful Guanyin Temple, dedicated to the Buddhist goddess of compassion. It's located 1.5km south of Chalok Lam on the left hand side of the cross-island road from Thong Sala as you head north, just before you reach the temple of Wat Paa Sang Tham (also well worth a look).
It's also worth checking out Wat Khao Tham, which sits among the dense foliage of trees high on a tranquil hill near Ban Tai – don’t miss the temple hall at the top of the steps that houses a sleeping Buddha. A bulletin board at the temple details a popular meditation retreat; see its website (kowtahm.com) for details.
Other temples on the island include Wat Phu Khao Noi, Wat Pho and Wat Chaloklam. When visiting Buddhist temples, remember to change out of your beach clothes.
