About UPPER LOON CREEK Hot Springs
UPPER LOON CREEK Hot Springs offers a raw, untouched escape deep in Idaho’s wilderness. The spring’s intense, 145°F waters bubble naturally, providing a powerful thermal experience surrounded by dense forest and rugged terrain. This primitive hot spring invites you to immerse yourself in a quiet, elemental setting far from the beaten path.
Getting There
Reaching UPPER LOON CREEK Hot Springs requires a challenging hike along steep, often uneven trails that demand sturdy footwear and a good level of fitness. Parking is limited at the trailhead, and expect to carry your gear over several rough miles through Idaho’s backcountry. Navigation skills help, as signage is minimal.
What to Expect
The hot spring is raw and undeveloped, featuring small pools formed by nature rather than constructed soaking tubs. Water temperatures near 145°F may feel intense, so dipping in gradually is key. You’ll encounter a serene atmosphere with few fellow visitors, but lack of amenities means solitude comes with primitive conditions—no restrooms or shelter.
Tips for Visitors
Visit during spring or fall to avoid insect swarms and excessive summer heat on the trail. Bring plenty of water, snacks, and a means to purify natural water sources since amenities are absent. Respect the fragile ecosystem by packing out all trash and using biodegradable soap if needed. The hot springs are free, but tread lightly to preserve this authentic Idaho swimming hole.
