Namtok Than Sawan, Phu Chi Fa

Cascading down moss-covered limestone cliffs in the remote mountains near Phu Chi Fa, Namtok Than Sawan offers one of northeastern Thailand’s most rewarding waterfall experiences. This multi-tiered cascade plunges through dense forest, creating natural pools perfect for swimming and a refreshing escape from Thailand’s tropical heat. The waterfall’s name translates to “heavenly waterfall,” and its pristine setting in Loei Province delivers exactly that celestial feeling.

The waterfall tumbles down several levels, with the main drop creating a spectacular curtain of water that crashes into a large, emerald-green swimming hole below. Cool mountain water provides relief even on the hottest days, while the surrounding jungle echoes with bird calls and the constant rush of falling water. Smooth boulders offer perfect perches for sunbathing or photography, and adventurous visitors can explore smaller pools and cascades both above and below the main fall. The mist from the cascade creates a natural air conditioning system, keeping temperatures pleasantly cool in the immediate area.

Tranquility defines the experience at Than Sawan, where the only sounds are rushing water and forest wildlife. The relatively challenging access keeps crowds minimal, creating an intimate atmosphere where you might have the entire waterfall to yourself. Swimming in the crystal-clear pools feels like discovering your own private oasis, while the surrounding old-growth forest provides a sense of being completely removed from civilization.

Visit during or just after the rainy season (June through November) when water flow is at its peak and the surrounding vegetation is most lush. The hike to reach the waterfall requires moderate fitness levels and sturdy footwear, as the trail can be slippery and steep in sections. Bring swimwear, water, snacks, and a waterproof bag for electronics. The challenging access and incredible natural beauty make this one of Loei’s most rewarding outdoor adventures for those willing to make the effort.
