Than Rattana Waterfall, Chonburi

Deep within Prachin Buri’s tropical wilderness, Than Rattana Waterfall offers one of eastern Thailand’s most rewarding jungle adventures. This multi-tiered cascade plunges through dense forest, creating natural swimming pools that remain refreshingly cool even during the hottest months. Unlike many of Thailand’s crowded waterfalls, Than Rattana maintains an untouched quality that makes every visit feel like a genuine discovery.

The waterfall tumbles down several rocky levels, with the main drop creating a substantial pool perfect for swimming and cooling off after the jungle trek. Crystal-clear water flows over smooth limestone rocks, while the surrounding canopy filters sunlight into dancing patterns on the water’s surface. You’ll hear the constant rush of falling water mixed with tropical bird calls and rustling leaves overhead. The air carries the fresh scent of wet earth and vegetation, creating an immersive natural experience. During peak flow periods, mist from the cascade provides natural air conditioning in the humid jungle environment.

Tranquility defines the experience at Than Rattana, where the only sounds come from nature itself. The surrounding forest creates an intimate setting that feels worlds away from Thailand’s busy tourist trails. Swimming in the cool pools while surrounded by towering trees and rocky walls provides a sense of peaceful isolation. Wildlife sightings add excitement to the serene atmosphere, with colorful birds and butterflies frequently spotted along the forest paths.

Visit during or shortly after the rainy season (June through November) when water levels are highest and the cascade is most impressive. The moderate hike through jungle terrain takes about 30 minutes each way, so bring sturdy shoes with good grip. Pack water, insect repellent, and a waterproof bag for valuables if you plan to swim. Early morning visits offer cooler temperatures and better wildlife spotting opportunities, making this free natural attraction well worth the adventurous journey into Prachin Buri’s pristine wilderness.
