What to do
Disc golf at Massacre Rocks: The state park maintains an on-site course perfect for casual players. "Bring your disc golf, your fishing pole, and your chair for the evenings! Quiet, restrooms and showers were clean," notes one Massacre Rocks State Park Campground visitor.
Hiking to historical sites: Several trails lead to Oregon Trail landmarks and unique geological features. At Massacre Rocks, campers can "enjoy the hike/walk out to the Oregon Trail wagon ruts" according to a visitor who appreciated the accessibility of historical sites from the campground.
Wildlife viewing opportunities: The wetlands around Lake Walcott State Park Campground provide excellent bird watching. "The deer tend to come in in the early evening hours to enjoy the park too and are not very spooked by people," reports a camper who observed the regular wildlife patterns.
Fishing along the Snake River: Multiple access points allow for productive fishing. "Amazing campground and beautiful views. Hardly anyone here! Great fishing in the Snake River," notes a Massacre Rocks visitor who found uncrowded angling spots.
What campers like
Spacious sites with privacy: Many campers appreciate the well-designed layout at certain parks. "The sites are HUGE and really offer a great deal of privacy and seclusion," reports a visitor to Smoky Mountain Campground — Castle Rocks State Park.
Dark skies for stargazing: The remote location offers exceptional night viewing. A Castle Rocks visitor noted, "It was such a clear night (and so dark in the campground) that we could see hundreds of stars and fell asleep looking at them."
Lake access directly from campsites: Waterfront options provide convenience for boaters. At Willow Bay Resort, "This campground has plenty of trees, and shade and access to the reservoir. Boat launches," according to a satisfied camper.
Clean shower facilities: Visitors consistently mention the quality of restroom facilities. One Lake Walcott camper noted "The bathrooms are also well cleaned even on a high use weekend but small, 2 stalls each—all showers were working."
What you should know
Seasonal insect activity: Depending on timing, bugs can be an issue at some parks. At Lake Walcott, "There were non stinging flying insects all up in our face and flying up our nose. We got a few Mosquito bites but nothing above normal for a summer evening—the insects go away if you start a smoky fire."
Limited water access for tent campers: Some campgrounds have restrictions. "The only real problem is the lack of a sink for tent campers—we couldn't wash our dishes after meals. There is water but it's for the RV sites so bring water to drink and a camp sink for the washing up," reports a Lake Walcott visitor.
Dam operations cause occasional noise: Proximity to hydroelectric facilities affects some campgrounds. At Lake Walcott, "The park is also part of an electric dam project so you'll hear an alarm every once in a while but it's not very loud."
Off-season limitations: Facilities close during winter months at some parks. A visitor to Castle Rocks noted, "We were disappointed to find that all the water and restroom facilities were closed during the winter."
Tips for camping with families
Recreation amenities for children: Some parks offer extensive activities. At Anderson Camp RV Park, "Lots to do for young children with a large playground, two shallow (2-3ft?) small outdoor pools, one with a water slide (swim and use at your own risk, not attended), putt putt golf."
Protection from wildlife: Take proper precautions with food storage. A Lake Walcott visitor advised, "The park is a wild life refuge so we saw Deer and Racoons at night. We kept all food items in out car to avoid issues."
Proximity to bathrooms: Consider site location when traveling with small children. While some cabins are conveniently positioned near facilities, others require longer walks to restrooms.
Group site options: Several campgrounds accommodate family gatherings. One Lake Walcott visitor mentioned, "Our group of 9 reserved sites 26 and 25" showing the availability of adjacent sites for larger parties.
Tips from RVers
Site leveling challenges: Some campgrounds require additional preparation. At Twin Falls-Jerome KOA, a visitor noted that "everything worked quite well, my pool Throughs and the areas were relatively flat."
Highway noise considerations: Location relative to Interstate 84 affects some parks. At Twin Falls-Jerome KOA, "if you are on the last row, that makes you closest to the highway and you will hear the highway noise starting at about 5:30 in the morning."
Hookup placement varies: Utility connections may require extra equipment. At Anderson Camp, visitors found that "hookups are oddly located and the spots are tight."
Dump station availability: Not all parks offer on-site dumping. At Castle Rocks, "There is a dump station on the road to the grounds but it was closed for repairs when we visited."
