Cascading through dense tropical forest in Ubon Ratchathani’s remote eastern reaches, Namtok Soi Sawan presents one of Thailand’s most pristine waterfall experiences. This multi-tiered cascade drops dramatically over limestone cliffs, creating natural pools perfect for swimming. Far from the crowded tourist circuits, the waterfall maintains its wild character, surrounded by untouched jungle that echoes with bird calls and insect symphonies.
Seven distinct tiers tumble down the rocky face, each creating its own swimming hole with crystal-clear water that stays refreshingly cool year-round. The main pool at the base offers the best swimming, deep enough for proper dips and surrounded by smooth boulders ideal for sunbathing. Adventurous visitors can scramble up the rocky sides to explore higher pools, each offering different perspectives of the falling water. The surrounding forest buzzes with tropical life – colorful butterflies dance around flowering vines while the constant sound of rushing water mingles with jungle sounds.
Peace defines the Soi Sawan experience, broken only by the therapeutic sound of water meeting stone. Few tourists venture this far into Ubon’s countryside, making it feel like a personal discovery. The jungle setting creates a natural sanctuary where time slows down, encouraging long afternoons spent swimming, exploring, or simply sitting beside the pools listening to nature’s soundtrack.
Visit during or just after the rainy season (June through November) when water flow reaches its peak, though the falls run year-round. A moderate 20-minute hike through forest trails leads to the main cascade – wear sturdy shoes as paths can be slippery. Bring swimwear, drinking water, and perhaps a picnic to fully enjoy this natural retreat. The free admission and lack of commercial development make this an authentic slice of wild Thailand worth the journey into Khong Chiam district.
