Lava Hot Springs sits in southeast Idaho along US-30, tucked between the mountains about 30 minutes east of I-15. It's easy to reach from multiple directions, and the drives — particularly from Jackson Hole and through the Snake River Valley — are scenic enough to make the journey part of the experience.
Whether you're driving from Boise, flying into Salt Lake City, or road-tripping from Jackson Hole, this guide covers every route and option.
From Boise
The capital-to-hot-springs route crosses the Snake River Plain on major highways.
Distance: 220 miles Drive time: 3 hours (summer), 3-3.5 hours (winter) Route: I-84 East to I-86 East, exit to US-30 East into Lava Hot Springs
The Drive
This is mostly interstate driving across southern Idaho's agricultural landscape. I-84 heads east out of Boise through the Snake River valley, past Twin Falls (a good halfway stop), then I-86 takes you southeast toward Pocatello before you exit onto US-30 for the final stretch into Lava Hot Springs.
Key Stops Along the Way
Twin Falls (Mile 130) Halfway point with full services — gas, restaurants, shopping. The Perrine Bridge over the Snake River Canyon is worth a quick stop. Base jumpers frequently leap off it.
Burley/Rupert (Mile 170) Smaller towns with gas and fast food. Reliable stop if you skipped Twin Falls.
American Falls (Mile 190) Small town with the American Falls Reservoir visible from the highway.
Pocatello (Mile 200) Full-service city — groceries, gas, restaurants. Last major stop before Lava Hot Springs. If you need to stock up on groceries, do it here.
Seasonal Considerations
Summer: Straightforward 3-hour drive on major highways. I-84 and I-86 are well-maintained interstates.
Winter: Generally clear — these are major interstate routes that get priority plowing. US-30 from I-15 to Lava is a smaller highway but well-maintained. Check Idaho 511 during storms.
From Salt Lake City
The most popular route for visitors from the south and the shortest drive from a major metro area.
Distance: 160 miles Drive time: 2.5 hours Route: I-15 North to Inkom/Lava Hot Springs exit, US-30 East into town
The Drive
One of the easiest drives to any hot springs destination in the West. I-15 North out of Salt Lake City climbs through northern Utah, crosses into Idaho near Malad City, and continues north past Pocatello. Exit at Inkom or McCammon and follow US-30 East into Lava Hot Springs.
Key Stops
Brigham City, UT (Mile 60) Last Utah town with full services before the Idaho border.
Malad City, ID (Mile 90) Small Idaho town just past the state line. Gas available.
Inkom, ID (Mile 140) Home of Pebble Creek Ski Area. Nearly to Lava Hot Springs — 15 minutes to go.
Why SLC Visitors Love This
- Under 3 hours from downtown Salt Lake City
- Entirely on interstate until the final 15-minute stretch
- Natural hot springs without the Wasatch Front crowds
- A different vibe from Park City or the Utah resort scene
- Affordable alternative to Utah hot springs facilities
Winter Driving
I-15 through northern Utah and southeast Idaho is a major corridor — well-maintained in winter. Chains are rarely needed. The short stretch on US-30 is fine in normal winter conditions.
From Pocatello
The closest city to Lava Hot Springs, making it an easy day trip or the last supply stop.
Distance: 35 miles Drive time: 30 minutes Route: I-15 South to US-30 East
Why This Matters
Pocatello is where you'll find:
- Grocery stores — Albertsons, WinCo, Walmart for stocking up
- Pocatello Regional Airport — The closest airport
- Idaho State University — Campus town energy, more restaurant options
- Pebble Creek Ski Area — Just outside Pocatello in Inkom, between the city and Lava
Many visitors fly into Pocatello or Salt Lake City, rent a car, and stock up on groceries in Pocatello before the 30-minute final drive.
From Idaho Falls
Northern approach through the Snake River Plain.
Distance: 100 miles Drive time: 1.5 hours Route: I-15 South to US-30 East
The Drive
Straightforward interstate drive south on I-15, then a short stretch on US-30. Idaho Falls to Pocatello is about an hour; Pocatello to Lava Hot Springs is another 30 minutes.
Why Start from Idaho Falls?
- Idaho Falls Regional Airport — Good flight connections, especially from Denver, Salt Lake City, and seasonal routes
- Gateway to Yellowstone — If combining a Yellowstone trip with Lava Hot Springs, Idaho Falls is the natural hub
- Larger city services — Hotels, restaurants, and outfitters if you need to stage before heading south
From Jackson Hole
The adventure route — combining two of the Mountain West's great destinations.
Distance: 170 miles Drive time: 3 hours Route: US-26 West through Swan Valley to Idaho Falls, then I-15 South to US-30 East
The Drive
This is the scenic route. US-26 from Jackson, Wyoming through the Snake River canyon and Swan Valley is one of the most beautiful drives in the region. You'll pass through the Caribou-Targhee National Forest and drop into the Snake River Plain before reaching Idaho Falls, then south to Lava Hot Springs.
Why Combine Jackson + Lava
- Grand Teton + hot springs: World-class national park paired with genuine mineral soaking
- Price contrast: After Jackson Hole prices, Lava Hot Springs feels like a bargain
- Vibe contrast: After Jackson's tourist energy, Lava's small-town calm is restorative
- Road trip gold: The drive between them is gorgeous
Winter Considerations
US-26 through the mountains can be challenging in winter. Check conditions before departing. Teton Pass (if coming from the town of Jackson) is steep and frequently snow-covered. The alternative is going south through Alpine and Star Valley, which adds time but avoids the pass.

Fuel Planning

- Gas options in Lava Hot Springs are very limited
- For day trips, top off before heading out — distances to next gas can be significant
