Castle Rock Campground sits within Fishlake National Forest, serving Utah's Fremont Indian State Park and offering 44 camp sites at elevations around 6,000 feet. Despite proximity to Interstate 70, the campground is positioned far enough up a side canyon that traffic noise is minimal. Approximately two-thirds of sites are reservable while the remainder are first-come, first-served, with many sites located alongside a creek that flows through the grounds.
What to do
Hiking from campgrounds: Several trails connect directly from camping areas, providing easy access to both natural areas and cultural sites. "There is a nice trail out of the south end of the campground that follows a stream, and plenty of trail and hikes across I-70 starting at the visitors center," notes camper Barry S. at Castle Rock Campground.
Rock art exploration: The region contains numerous accessible petroglyph panels beyond those mentioned at the visitor center. "The campground is very nice. You are close to the Fremont Indian exhibit and trails. There is also a nice trail that leads up into the Fishlake National Forest. Lots to see! There are red rock pillars, yellow aspen and native american art," reports connie C.
Soak in natural hot springs: Multiple hot spring options exist near Marysvale, providing mineral-rich waters with distinctive soaking arrangements. "We've been here in the summer and winter. Stayed in one of their buses and camped. Both times have been fun experiences," explains Sarah S. about her visits to Mystic Hot Springs.
ATV trail access: Direct connections to the Paiute ATV trail system can be accessed from several campgrounds in the area. "There is an access road from the campground to the Paiute ATV trail," reports a camper staying at Castle Rock.
What campers like
Off-highway quiet: Despite being near major roads, many campgrounds provide unexpected tranquility. "Despite being close to the interstate, it is far enough up a side canyon that you do not hear the traffic on the road. It feels like being much further from civilization," writes Barry S. from Sam Stowe Campground.
Reasonable pricing: Area campgrounds maintain accessible rates for various accommodation types. "Tent camping at site 23. $20 for a tent site ($40 for a double site). Cool area to explore. Fire pit and a faucet with a bucket. Bathrooms close by. $5 for a bundle of wood. Nice little spot!" shares Stoney K.
Clean facilities: Multiple reviewers note the well-maintained nature of campground facilities throughout the region. "The campground is very well maintained and the FF sites were empty except for mine and another all weekend so don't worry if the reservation area is full," explains Perle T., adding "Verizon and T-Mobile service enough for hot spot and road is drivable for any rig."
Stargazing opportunities: The area offers exceptional night sky viewing with minimal light pollution. "The night sky was magnificent and may have made up for our inability to shower for a couple days. We were the only ones in the park, Winter camping. It's located in a dark sky area, so the skies are clear and the air is clean," writes Carlyne F. about her stay at Sand Creek RV, Cabins, Tents.
What you should know
Seasonal facility changes: Some campgrounds reduce services in winter months but remain open. "They're still open in the Winter, but we didn't find out they closed their showers and bathrooms until we were told upon arrival. (They close 10/31)," warns a camper about Sand Creek RV.
Reservation systems vary: Campgrounds operate under different reservation policies, with some requiring advance booking while others follow first-come systems. "It's first come first serve. We called Fremont Indian State Park rangers to see if there were any open spots. They were very helpful and friendly," reports Jiwon K.
Wind considerations: Exposed campsites in this high-desert region can experience significant wind, affecting comfort levels. "The site had nice views but is very exposed and very very windy which means we kept time outside of the van to a minimum as it wasn't very relaxing. There are wooden shelters for tent spots to mitigate the wind," explains Kayleigh T. at Sand Creek.
Water availability: Most established campgrounds provide water access even at primitive sites. "There were plenty of water taps around the campground to fill up jugs if need be, along with a bucket and shovel at each spigot to use for your fire pit," notes Mikki S. from Fillmore KOA.
Tips for camping with families
Campground amenities for children: Several properties maintain facilities specifically designed for younger campers. "We really enjoyed our time at the Fillmore KOA. The campground and facilities are very clean and well maintained. The camp hosts and staff are very friendly," shares Jill L.
Educational opportunities: Glamping in Marysvale, Utah puts families close to learning-centered experiences at multiple sites. "This campground is also a place to camp for enthusiasts of the Paiute Trail, a large network of ATV trails as it had a trail near the northern end of the campground. Our 24' pop up truck camper fit just fine and had enough room for my sister's SUV," notes Judy T. about her stay at Castle Rock.
Pet considerations: Most area campgrounds welcome pets but may have specific restrictions or designated areas. "Wonderland RV Park has shady spots to park. Small and mostly quiet with cows and ducks in a field next to the campground. Close to Capitol Reef and Bryce Canyons," comments Dene H. from Wonderland RV Park.
Off-season family camping: Certain times offer reduced crowds while maintaining access to main attractions. "Family stopped to check out on the 3rd of July and there were many open spots. Had a 29' toy hauler and the roads in camp were good for us. There were a few pull through spots that made it easy," observes A T. about Castle Rock.
Tips from RVers
Space considerations: RV campsite configurations vary considerably between properties in the Marysvale region. "Castle Rock campground in Fishlake National forest is one of two campgrounds that serve Utah's Fremont Indian State Park. There are 44 camp sites available, many alongside the creek that flows through the campground. Several are double sites for larger groups, and there are a variety of pull through vs in/out options," explains Barry S.
Hookup availability: Luxury glamping in Marysvale, Utah often includes full utility connections, but these differ by property. "Great location if you ATV or just need a night along Interstate 15.

Cell service access: Connectivity varies by location and provider. "Verizon and T-Mobile service enough for hot spot and road is drivable for any rig," reports a camper from Castle Rock Campground.
Weather preparedness: High desert climate means significant temperature swings between day and night. "We stayed at site CA23, a dispersed site.
