About BILLY Hot Springs

BILLY Hot Springs offers an authentic Idaho experience with its naturally warm waters nestled in a rugged landscape. This primitive hot spring invites you to soak surrounded by untouched wilderness, where the quiet sounds of nature enhance the calm. It’s a raw and peaceful spot that highlights the beauty of Idaho’s natural hot springs.

Getting There

Reaching BILLY Hot Springs requires a bit of adventure, as it lies off the beaten path accessible by a high-clearance vehicle or a moderate hike. Parking is limited near the trailhead, and you should be prepared for rough terrain and some walking to reach the pools. This remoteness helps maintain its quiet charm but does call for proper navigation and preparation.

What to Expect

The spring pools vary in temperature and size, with soft mineral-rich water that feels soothing against your skin. The atmosphere is tranquil, often allowing for a solitary soaking experience away from crowds typical of more developed springs. Facilities are minimal to non-existent, emphasizing an unspoiled, backcountry feel.

Tips for Visitors

Visit during shoulder seasons to avoid peak summer crowds and enjoy cooler air that contrasts nicely with the hot water. Bring ample water, sturdy footwear, and respect the delicate environment by packing out all trash. There are no fees, but practicing Leave No Trace ethics preserves this gem among Idaho swimming holes.
