"This was a nice little spot to car camp, located on a rock road. Got there just before sunset and was able to snag a cute little spot along the river."

"GPS correct, no signage and just off highway West. Small 60x40 yard gravel/dirt lot a quarter mile up improved road with some potholes."
"Just a quick turn off from the main Highway on a flat and smooth dirt road. The site is one huge Loop so stop and park wherever you want. There's one tree that I parked under for shade."
"A short dirt road that’s well maintained leads up to a rock/gravel parking lot. As another reviewer said, the right is for camping, while the left is day use only."
"Nice spot in a gravel parking lot surrounded by small mountains with toilets nearby. Park on the right as camping is prohibited on the left."

"Good access to the streams. We parked in front of a trailhead that allows motor bikes, horses and hikers. Fire rings along the sites and level land. Peaceful night sleep."
"It might be alluring to go all the way down the dirt road, but best spots are towards entrance. Big power lines that overtake the area further down road."

"Easy access from Lava with about 10 designated spots, most with room for two vehicles and one(?) pull through spot that fit my truck/30foot TT."
"The trail along the river is awesome though!"
TravelerVery helpful, easy to find dispersed camping just off the interstate. The highway noise is audible but not irritating. Great for a quick overnight. Appreciated the convenience of its proximity to traveling on highway 30 or I-15.
GuideThe camper sites are big. Kinda rough and weedy though. The trail along the river is awesome though!
TravelerNice level spots - interesting views by the river - toilet - close to lava hot springs but…the train went by several times during the night and blew its horn so many times it was a poor nights sleep
TravelerDecent spot that's just off the highway. Easy to find the main road, gravel. Washboard road is ok if you go slow. Off road is rougher than it looks. Highway noise is not terrible. Decent spot for a short stay. Close to the truck stop with public restroom too.
ScoutThis area is next to the Snake River, with lots of trees and brush, that are loaded with birds.
The access road is a well graded with dirt and gravel. Fishermen use this as a high speed at times, transportation route for their boats and vehicles to up river access. There can be a lot of dust and noise when the traffic is high. Most of the traffic stops after dark.
There are some sites that are along the river and some away from the river. A few sites are fairly private. There are quite a few places to get larger rigs or groups in.
There are a few spots that are level, but most are not.
We arrived late in the day, middle of the week in mid-June and most sites were already taken.
We did end up finding a nice spot near the river, and spent a pleasant evening and night.
People do seem to be leaving a lot of trash in these sites. Spent quite a bit of time picking up food packages and other assorted garbage.
The only toilet we saw was at the entrance to the area. It was clean and well stocked.
We would stay again.
ScoutWould have been a 5 star spot if it weren’t for the mass amounts of used toilet paper and trash left at multiple sites. The forested area surrounding my spot smelled rancid of human waste. Plastic grocery bags filled with waste and toilet paper tumbleweeds really tainted the beautiful river view.
GuideStayed here for four nights and other than highway noise it wasn't bad. Its a long gravel road to the sites but there are plenty to choose from once you get towards the end.
GuideGreat free spot for visiting nearby Lava Hot Springs. Be sure to approach from the south (McCammon freeway exit) - The road is nicely maintained up to the campground but horrible continuing north.
TravelerDuring the day it's busy with family activities, playing in the water or riding atvs. At night it dies done and gets quite. Soon you can hear the loons and crickets. Off note if you have an adhd child be prepared to do something all day.
