About South Fork Plunge
South Fork Plunge is a raw, steamy hot spring tucked into the rugged landscapes of Idaho, where water bubbles up at a sizzling 129°F. This primitive soak offers an intense, natural encounter with the earth’s geothermal energy, ideal for those drawn to untamed swimming holes in Idaho.
Getting There
Reaching South Fork Plunge demands a sturdy spirit and some grit—you’ll trek along a rough, unmarked trail that snakes through dense forest and rocky terrain. Parking is limited near the trailhead, so arrive early to secure a spot and prepare for a moderately challenging hike.
What to Expect
At South Fork Plunge, the water’s intense heat and rustic pools immerse you in a wild atmosphere far from modern comforts. Expect little more than the raw spring and nature’s soundtrack; crowds are rare due to its remote location, enhancing the solitude but also the need for self-sufficiency.
Tips for Visitors
Aim to visit during cooler months or weekdays when fewer hikers are on the path. Bring plenty of water, sturdy footwear, and gloves if you plan to adjust rocks for cooler spots. There are no fees or facilities—respect the land by packing out everything you bring in and watch your step on the natural terrain.
