Halfway along the trail linking Hat Railay East to Hat Tham Phra Nang, a sharp 'path' leads up the jungle-cloaked cliff wall to this hidden lagoon. The first section is a steep 10-minute uphill climb (with ropes for assistance). Fork right for the lagoon, reached by sheer downhill climbing. If you fork left, you'll quickly reach a dramatic cliff-side viewpoint ; this is a strenuous but generally manageable, brief hike.
