Camping opportunities around Lava Hot Springs, Idaho spread across a high mountain valley at 5,000 feet elevation. The camping season typically extends from late April through mid-October, with summer nights cooling significantly due to the elevation. Winter camping remains available at select locations but requires cold-weather preparation with overnight temperatures regularly dropping below freezing.
What to do
River recreation access: The Portneuf River at Portneuf River Lower Sportsman Access offers multiple water activities. "Beautiful view, less than five minutes to Lava and much better than paying the crazy prices in the camp grounds," notes one camper. The nearby waterfall creates a natural swimming area popular during hot summer days.
Hot springs visits: Campers staying at Lava Hot Springs West KOA value the walkable hot springs access. "Walking distance to the hot spring pools and a park where in the summer you can tube the river," reports a visitor. The mineral pools maintain temperatures between 102-112°F year-round and require a separate admission fee ranging from $7-15 depending on season.
Hiking trails: Several trails originate near Goodenough Creek Campground, offering moderate terrain suitable for day hikes. "Great hiking and horseback riding trails, quiet, not too crowded," notes one visitor. The trails follow creek beds and provide access to higher elevations with minimal technical difficulty.
What campers like
Quick town access: The central location of Lava Hot Springs Spa Motel & RV Park appeals to many visitors. "The location is directly across the street from the hot spring pools. At the back of the RV park is a trail you can walk along the river and will come to a place where you can enter the river right into a hot spring," explains one camper. Most attractions remain within a 10-minute walk.
Riverfront sites: Many campers appreciate direct river access, especially at sites along the Portneuf. "Beautiful & quiet. The train was really long but sleep with a fan on and you'll hardly hear it," notes one camper at Lower Portneuf Campground. The river's natural white noise helps mask occasional traffic and train sounds.
Free camping options: Budget-conscious travelers appreciate no-cost alternatives. "Level and fantastic site for an overnight stay," reports a visitor at Lower Portneuf Campground. While free sites lack hookups, they provide basic camping necessities including established fire rings and level parking areas.
What you should know
Train noise considerations: Multiple campgrounds near Lava Hot Springs experience regular train traffic. "The road is extremely bumpy so if your have a low car or trailer be careful. The cons, no shower, hook ups, store and the train that runs by Lava Hot Springs can be heard," warns a camper at Portneuf River Lower Sportsman Access. Train schedules vary but typically include multiple nighttime crossings.
Road conditions: Access roads to dispersed camping areas often require careful navigation. "The road up is a bit steep but doable. We drove a 38ft schoolie up here no problem. Only one pull through in the first loop most sites are a bit smaller. Beautifully tree covered area," reports a visitor at Goodenough Creek Campground.
Limited shower facilities: Many of the dispersed and BLM camping areas lack shower facilities. Visitors planning extended stays might need alternative arrangements. Several campgrounds offer pay showers for non-guests, typically charging $2-5 per use.
Tips for camping with families
Playground access: Lava Campground provides dedicated play areas for children. "Fun playground for kids and lots of room to run around. Right down the road of town and the hot springs," notes a visitor. The playground equipment accommodates various age groups and remains within sight of most campsites.
River safety: Families should note the Portneuf River varies in flow and current strength throughout the season. Life jackets remain essential for children, as parts of the river feature faster currents than appear from shore. Designated swimming areas provide safer alternatives to open river access.
Shade availability: Summer temperatures regularly reach 90°F, making shade crucial for family comfort. "The tent area is quite pretty and I really liked that the ground is large grain sand so it made setting up camp very easy. There are mature trees around so there is part or full shade for most of the area," explains a visitor at Lava Hot Springs East KOA.
Tips from RVers
Hookup availability: Established campgrounds offer varying levels of RV services. "Great pull-through and the back-in spots are beautiful. Kid, pet friendly, walking distance to food and fun," notes a visitor at Lava Hot Springs West KOA. Most developed campgrounds provide 30-amp service, though 50-amp connections remain limited throughout the area.
RV length restrictions: Several campgrounds limit RV size due to tight turns and space constraints. At Indian Rocks - Dispersed Camping, larger rigs require careful navigation. "Road is a little rough, but other than that it was great," reports one RVer. Most dispersed sites accommodate RVs under 35 feet, while larger rigs should target established campgrounds with pull-through sites.
Dump station locations: Limited dump stations exist within the immediate Lava Hot Springs area. "The KOA will let you fill your water tank for free but they charge $10 for a dump," notes a visitor. Planning ahead for waste management remains essential, especially for extended stays.
