Khlong Chak Waterfall

Khlong Chak Waterfall is the island's best-known inland attraction, a short trip into the forest for a cool dip and a change of scenery. It lies on the southern half of Ko Lanta Yai, on the eastern slope of the hills, and is reached by a short walk along a stream through the trees. The path is mostly shaded, and the sound of running water guides you to the falls, where a series of cascades empty into a pool deep enough for a swim. It is a favorite with families and with travelers who want a break from the beach, and the walk takes little time. There is a small fee for entry at the trailhead in some seasons, collected by the local community.

The waterfall is at its best after rain, usually from about May to November, when the water flows strongly and the pool is full. In the dry season the flow can drop to a trickle, and the cascades may be less impressive, though the forest remains cool and green.

It is worth asking locally about conditions before making the trip. The walk itself is short, often about twenty minutes each way, with some uneven ground, roots and rocks. Wear shoes with grip, because the path can be slippery, and bring insect repellent for the shade. Water shoes are useful at the pool.

At the falls you can swim in the pool below the main cascade. The water is cool and refreshing, and the surrounding rocks make good places to sit. Do not jump from rocks or attempt to climb the falls, because the stone is slick and there are no safety barriers. Keep an eye on children near the edge. Take your rubbish with you and use biodegradable sunscreen or none at all, since the water is part of a small ecosystem. You may see butterflies, birds, monkeys and, with luck, a monitor lizard along the trail.

Getting there is part of the adventure. The road from the main west coast route leads through rubber plantations and small villages, and the final stretch to the trailhead can be rough. Scooter riders should be careful on wet roads. Taxis and tuk-tuks can take you, and some local tour operators include the waterfall in a half-day trip with other southern stops. If you drive yourself, bring cash for the small fee and for a drink at the stall by the car park.

The waterfall suits families with children who can manage a short walk, couples who like a bit of nature and anyone wanting a rainy day activity. It is less suitable for people with mobility problems because of the uneven path. Combine it with a visit to the southern beaches or the national park, and plan to be back before dark.

Respect local rules, keep noise down and enjoy the pocket of cool shade that the forest provides on a hot day. If you are interested in nature, ask the staff about local plants and wildlife; many of the guides are residents with good knowledge.

If you are deciding whether the detour is worth it, think of it as a half-day of cool shade rather than a dramatic sight. The falls are modest by the standards of Thailand's bigger waterfalls, but the forest setting, the clear stream and the swim make it a pleasant change from salt water. It is especially welcome in the heat of the afternoon, and it is a good plan for a day when the sea is too rough for boats.
