Irwin, Idaho camping areas range in elevation from 5,500 to 7,000 feet, creating microclimates that impact camping comfort throughout the seasons. The region sits at the Idaho-Wyoming border where the Snake River emerges from Palisades Dam, creating both still reservoir waters and flowing river conditions. Campers often experience 30-40°F temperature drops at night even during summer months.
What to do
Fishing access points: Falls Campground provides multiple fishing spots along the Snake River. "The birds are singing away and the air is fragrant from the flowering shrubs and trees," notes Janice G. about the Falls Campground environment where many anglers gather.
Mountain biking trails: Access some of the area's best single-track directly from your campsite. "What most don't know is that it offers access to some of the best Mtn Bike Trails in our area. Rush hour, Nemo, and Mail Cabin are all great rides," explains Fletcher W. about Mike Harris Campground.
Wildlife viewing: Look for moose and bald eagles that frequent the area. Michelle E. reported from Falls Campground: "Moose were seen in the area and bald eagles were plentiful. There are beautiful falls close by as well."
What campers like
River proximity: Campsites situated right on the water's edge. "We pulled in late at night and grabbed a spot. The campground host, who visited us upon arrival was extremely helpful and allowed us to move closer to the river. Our second site had a fabulous view of the river," reports Pamela M. about Riverside Park Campground.
Clean facilities: Several campgrounds maintain exceptionally clean restrooms. "The pit toilets were also spotless - the cleanest I've ever seen," notes Alicia G. about Mike Harris Campground, while another camper mentioned, "The hosts are accommodating, friendly, and keep this campground in pristine condition. The toilets are spotless."
Beach access: Shoreline camping with sandy beach areas. "This site was super clean and had water spigots close by with clean pit toilets. Easy to navigate with our 19' trailer," Brandon S. explains about their experience at Falls Campground near the water.
What you should know
Bear safety requirements: Bear boxes are mandatory at some campgrounds. "All Food MUST be stored in a hard-sided camper or the provided Bear Boxes, there are both Grizzly and Black Bears in the area!" warns Ellen W. about the Mike Harris area.
Weather variability: Prepare for significant temperature swings. "It is hot here in the middle of July. We stayed in site 3, which is a double site and close to the entrance," notes Michelle E. at Falls Campground, while others mention cooler nights requiring warm sleeping gear.
Reservation systems: Many sites operate on first-come basis with limited reservation options. "One week spent early Aug 2020. Site sizes are fantastic. Staff was wonderful... esp Judy and her husband," shares Tammy L. about Gros Ventre Campground, which fills quickly during peak season.
Tips for camping with families
Playground options: Some campgrounds offer dedicated children's play areas. "They also have large RV/camper spots, tent spots, and cabins. There's a play area for children too," notes Joey and Lauren T. about Hover Camp in Swan Valley.
Kid-friendly hiking: Trails with manageable elevation gains for younger hikers. "Really awesome trail that connects," mentions a reviewer about Palisades Creek Campground, which offers paths suitable for various skill levels.
Safe swimming areas: Protected beach areas with gradual entry points. "Quiet and beautiful. The water was low when we arrived, but we could see the water from our spot," describes Clay H. about camping near the reservoir, adding "several people including large trailers were set up on the shore."
Tips from RVers
Site leveling challenges: Some spots require extra work to level larger rigs. "We snagged a great site tucked between huge trees. It had a fire pit, picnic table, level tent site as well as an oversized parking spot that was easy to level the trailer," explains Alivia M. about Riverside Park.
Hook-up availability: Limited full-service sites available. "Seven RV sites with full hookups ($32.50/nite), four tent spots, and three cabins. Each cabin has different facilities ranging from partial to full bath," explains Lee D. about Hover Camp.
Road access considerations: Some campgrounds have challenging approaches. "The roads in can be a little tricky without a raised truck and 4 wheel drive when towing a large 5th wheel. But once you pick a spot it is so beautiful," advises Joshua W. about Indian Creek.
