Lava Hot Springs is one of Idaho's most charming destinations — a tiny resort town of around 400 people in southeast Idaho's Bannock County, famous for its natural mineral hot springs, summer river tubing, and a growing food and lodging scene that punches well above its weight.
Whether you're soaking in chemical-free mineral pools, floating the Portneuf River, or using the town as a base camp for Yellowstone and Grand Teton day trips, this comprehensive guide covers everything you need to plan your visit.
Why Visit Lava Hot Springs?
Lava Hot Springs offers something you won't find at more commercialized hot springs destinations: completely natural mineral water with no chemical treatment and no sulfur smell. The pools are maintained by the city, fed by underground springs at 102-112 degrees Fahrenheit, and open year-round.

- Natural mineral hot springs with zero chemical additives — no chlorine, no sulfur odor
- World-class river tubing on the Portneuf River every summer
- Olympic-style outdoor swimming complex (separate from hot springs)
- Gateway to Yellowstone (~2.5 hrs), Grand Teton (~2 hrs), and Bear Lake (~1.5 hrs)
- Small-town charm without tourist-trap pricing
- Growing restaurant and lodging scene with genuine character
- 5,000 feet elevation in a scenic river valley

Best Time to Visit
Summer (June - September)
Peak season. The Portneuf River tubing is in full swing, the Olympic swimming complex is open, and long days mean more time for soaking, hiking, and exploring.
Summer highlights:
- River tubing and kayaking on the Portneuf
- Olympic pool and waterslide complex
- ATV trails and horseback riding
- Outdoor dining at local restaurants
- Warm evenings perfect for late-night soaking
Winter (December - March)
Arguably the most magical time to visit. Soaking in steaming mineral pools while snow falls around you is an experience that stays with you.
Winter highlights:
- Snow-surrounded hot springs soaking
- Pebble Creek skiing (30 minutes away in Inkom)
- Snowmobiling on nearby trails
- Cozy dome retreats with private soaking

Shoulder Seasons (April-May, October-November)
Fewer crowds, lower prices, and comfortable soaking temperatures. Spring brings wildflowers; fall brings golden cottonwoods along the Portneuf.

- No chemical treatment whatsoever — the water is naturally clean mineral water
- No sulfur smell — unlike many hot springs, these pools smell fresh
- City-maintained — clean, well-managed, and accessible
- Multiple temperature zones — pools range from 102 to 112 degrees Fahrenheit
