The best Koh Phangan waterfalls are Than Sadet for a full park with rock pools, Phaeng and Paradise for quick stops on the main road, and Wang Sai for a hidden jungle pool. Which one to pick depends mostly on the month, because several of them carry little water outside the rainy season.
This guide covers the Koh Phangan waterfalls one by one, with entry fees, how to reach them and the best time to go. It draws on Thai Holiday Guide for Than Sadet and Home Is Where Your Bag Is for Phaeng, Paradise, Wang Sai and the viewpoints, both read on 6 November 2026.

Than Sadet in Than Sadet National Park is the fullest visit, with a 2.5 km river, several waterfalls and rock pools, per Thai Holiday Guide.

Koh Phangan Waterfalls at a Glance

|---|---|---|---|

| Phaeng | In the national park, off the Thong Sala to Chaloklum road | Free, parking only | Little water outside the rainy season |

Most of the Koh Phangan waterfalls are on the north side, so they combine well with a stay near Chaloklum or Thong Sala. See our where to stay in Koh Phangan guide for the areas.
Than Sadet: The National Park Among the Koh Phangan Waterfalls
Thai Holiday Guide describes Than Sadet National Park as a 2.5 km river running through the jungle, with several waterfalls and rock pools, plus a trail that follows the river inland. It is open daily from 08:30 to 16:00 and costs 100 baht for foreign adults and 50 baht for children, cash only. The park is a short ride from Thong Nai Pan Yai, and the guide suggests showing the Thai-script address to a taxi or Grab driver.
The park also has a carved boulder near the river estuary that local tradition links to King Chulalongkorn (Rama V), who visited in 1888, and a small beach at the river mouth with a few bars and guesthouses. The pools are deep enough for swimming, but rip currents can form at the river-mouth beach, so check the flags. Thai Holiday Guide recommends a weekday morning, before organised ATV groups arrive.
How to plan Than Sadet
Go on a weekday morning, bring cash for the 100 baht fee, and combine it with Thong Nai Pan beach nearby. Our Thong Nai Pan Beach guide covers the bays.
Phaeng and Paradise: Roadside Koh Phangan Waterfalls
Home Is Where Your Bag Is places Phaeng Waterfall in Than Sadet National Park, at a signposted turnoff on the main road between Thong Sala and Chaloklum, about 10 minutes by scooter from Thong Sala. There is no fee except parking, and you reach the natural pools by walking a little upstream. Paradise Waterfall is a little further north, with the turnoff on the right about 5 more minutes towards Chaloklum. It costs 20 baht including a small water bottle. Both carry little water in the dry season.
Wang Sai: The Hidden One Among Koh Phangan Waterfalls
Wang Sai Waterfall is at the northwest tip of the island, in the village before Mae Haad Beach and Koh Ma, as part of Wang Sai Adventure Park. You pass the bar on the left and walk through the jungle to multi-level natural pools where you can swim a little. Home Is Where Your Bag Is calls it the least visited of the Koh Phangan waterfalls because of its hidden location, and says it is usually worth a visit only in the rainy season.
Viewpoints and Hikes Near the Koh Phangan Waterfalls
Several viewpoints sit close to the Koh Phangan waterfalls. Domesila Viewpoint starts at the foot of Phaeng Waterfall and takes about 15 minutes, with a staircase, a jungle path and some rope sections. A Chinese temple viewpoint, listed under the Goddess of Mercy Shrine, is a little north of Phaeng on the left side of the main road, and a viewpoint near Phaeng looks over Ko Tae Nai.
For a longer climb, Khao Ra is the island's highest mountain at 627 m, and the guide gives about 2 hours up through thick scrub and steep slopes. The Bottle Beach viewpoint is a short jungle hike at the eastern end of the beach, with a rock to climb and no safety rail, so wear proper shoes. Our Bottle Beach guide covers the beach itself.

| Months | Conditions | What it means for waterfalls |
|---|---|---|
| January to September | Driest period | Phaeng and Paradise carry little water; Than Sadet and its pools are the safer pick |
| October to December | Rainy season, November wettest | More water at Phaeng, Paradise and Wang Sai, but heavy rain and rough seas |

So the best time for the Koh Phangan waterfalls is a trade-off: the waterfalls fill up in the weeks when the beaches are at their worst. Our Haad Rin weather guide has month-by-month detail for the south of the island.
