Riverside Inn and Hot Springs

## Overview Riverside Inn and Hot Springs is an adults-only hot spring spa and boutique hotel nestled in the charming town of Lava Hot Springs, Idaho — a community long celebrated for its geothermally heated mineral waters along the Portneuf River in Bannock County. The property offers an intimate soaking experience with 3 indoor and outdoor hot spring pools, an 18-room hotel, a relaxing lounge, and an on-site restaurant. Unlike the larger public pools in town, Riverside Inn provides a quieter, more refined atmosphere geared toward adult guests looking to unwind. Lava Hot Springs sits along a geothermal corridor where naturally heated water rises to the surface through ancient volcanic rock formations. The town's hot springs have been used for centuries — the Shoshone and Bannock peoples considered the area sacred and used the mineral-rich waters for healing and ceremony long before European settlers arrived. The springs were later developed into public and private bathing facilities in the early 20th century, and the town has been a destination for hot spring enthusiasts ever since. ## Directions The Riverside Inn and Hot Springs is located at 255 Portneuf Street, Lava Hot Springs, ID 83246 (GPS: 42.6198, -112.0091). 1.
