Island Park, Idaho sits at an elevation of about 6,500 feet in the caldera of an ancient volcano. The area receives significant temperature fluctuations even during summer months, with nighttime temperatures often dropping into the 30s-40s°F even when daytime temperatures reach the 80s. Dispersed camping areas like Henry Flats offer waterfront access without facilities, while established campgrounds provide varying levels of amenities from basic vault toilets to full hookups.
What to do
Fly fishing access: Near Targhee Creek, visitors can explore a 13-mile trail with seasonal wildflowers. "We saw some wild strawberries!" notes Cheyenne P., who found the location perfect at about 20-30 minutes from Yellowstone's west entrance.
Wildlife viewing opportunities: Camping at Henrys Lake State Park Campground provides opportunities to see moose and other wildlife right from your campsite. "Wildlife can be viewed from inside RV," according to James S., who has stayed at the park numerous times.
Paddling on calm water: The multiple lakes in the area provide paddling opportunities with stunning backdrops. "The free Kayak rentals are a plus also. We also saw a moose swim across the lake, get up on shore and run through the campground," reports George B. about his experience at Henrys Lake State Park.
Mountain biking: Several trails throughout the area accommodate mountain bikes, with routes of varying difficulty. Areas around Island Park have connections to broader trail systems that continue into surrounding public lands.
What campers like
Proximity to attractions: Staying near Island Park gives easy access to multiple destinations. "Very close to other places to visit; Yellowstone NP, Mesa Falls, Harriman State Park, Earthquake Lake, Big Spring, really too many to list," notes James S. from Henrys Lake State Park Campground.
Lake views: Henry Flats Dispersed Spot provides waterfront camping with mountain backdrops. "An easy to get to, beautiful, quiet, and peaceful lake setting. Cows mowing in the distance, bird sounds on the water and sunset over the hills," writes Steve B. about this free camping area.
Peace and privacy: Many campers appreciate the secluded nature of camping options near Island Park. At Bootjack - Dispersed Camping, one reviewer mentioned, "I stayed here one night and loved it. I'm a solo female traveler and felt super safe which is important to me. There are quite a few surrounding campers, but not to the point where it feels overcrowded."
River access: Several camping sites near Island Park, Idaho provide direct river access. The Madison River at Bakers Hole Campground receives particularly high marks from anglers.
What you should know
Weather preparation: Wind can be significant at lakeside campgrounds. At Henry's Lake BLM Dispersed, a camper noted: "Tried to set up on the bluff having read the weather reports of only 8 mph winds, but up in the bluff overlooking the lake, gusts were at least 30mph. Had to pack up and move down by the boat access/pit toilets."
Early arrival recommended: Most dispersed camping sites fill quickly, especially during summer months. For popular areas like Bakers Hole Campground, campers advise: "Get there early for a spot. They have firewood available for purchase."
Insects: Depending on timing, insects can be problematic. At Henry's Lake BLM, a camper reported: "We loved it here, it was quiet for the most part and the lake was beautiful. Read in a previous review that the bugs were bad, and they definitely were but I would still recommend this place!"
Cell service variations: Connectivity varies greatly across the area. At Targhee Creek, reviews mention "Excellent Verizon service was a bonus that we don't get at a lot of dispersed sites," while other campgrounds report spotty coverage.
Tips for camping with families
Playground access: For families with children, Red Rock RV Park offers dedicated play spaces. According to Daniel C., "It has a huge playground area for the kids. Sorry no pool but Henry's lake is within a 1/2 mile."
Educational opportunities: The proximity to natural features provides learning experiences. Craig L. notes about Yellowstone Park-Mountainside KOA: "We were in tent site number one which they said was unlevel, but it was fine. It backed right up to the stream that gave an incredible calming sound all night long."
Safety considerations: When camping with children in this area, be aware of wildlife. At Targhee Creek, Brooke Z. advises: "If you plan on hiking, bring bear spray."
Temperature planning: Pack extra warm clothes for children even in summer, as nighttime temperatures can drop significantly regardless of warm daytime conditions.
Tips from RVers
Site selection: For larger RVs, look for pull-through sites at established campgrounds. Betty G. notes about Henrys Lake State Park: "There is one grassy area for tents and smaller RVs and a new section that will accommodate all sizes."
Road condition awareness: Many dispersed camping sites have rough access roads. At Targhee Creek, Ron D. explains: "The road is quite rough but I did fine in my small two-wheel drive SUV."
Leveling challenges: Many sites require leveling equipment. A camper at Henry Flats notes: "Location is stunning, off the main road, and feels safe. Additionally it is stunning! The lake is incredible, however it was VERY windy while we were there."
Hookup availability: Full hookup options exist but book quickly. Plan ahead for water access points if staying at dispersed sites, as most lack potable water.
