The Mills area offers camping options across Wyoming's high plains region, with elevations around 5,100 feet resulting in dry summer conditions. Temperatures can fluctuate significantly between day and night, with summer highs often reaching 90°F and dropping to the 50s after sunset. Camping sites range from established RV parks with full amenities to more secluded options with mountain views.
What to do
Fishing access: Gray Reef Reservoir provides fishing opportunities along the North Platte River. "Beautiful mountains and reservoir made for a lovely sunset. Nice vaulted toilet not far from our camp site. Site 5 is very private and off to the other side of the dam from the other sites, makes for a nice private spot," shares one Gray Reef Reservoir visitor.
Hiking and mountain exploration: Casper Mountain offers trails and forested areas just 15 minutes from town. "Awesome camping on Casper Mountain. 15 minutes to town makes it convenient. The camp sites are always kept up well," notes a camper at Beartrap Meadow County Park.
River activities: Multiple campgrounds offer river access for floating or wading. "We floated the river and docked right at the site, the kids loved the relaxing hammock park(at night there is twinkling lights in the trees), bonfires, community 'kitchen', there was a band during 4th of July!" reports a visitor at Memory Bridge Campground.
What campers like
River views and sounds: Many campers appreciate the water features near Mills. "Rush from the dam is a lovely background noise all night," mentions one Gray Reef Reservoir reviewer about the spillway ambiance.
Animal interactions: Beyond pet-friendly policies, some sites offer unique animal experiences. "In a word, the animal interactions were great as you walked among them. Dewayne was supper friendly and definitely from the cloth of a rancher," shares a visitor at Cloud Peak Llama and Alpaca Ranch.
Well-maintained facilities: Cleanliness stands out in reviews. "Very clean bathroom/showers. A couple have been remodeled. Nice laundry room. Free mini golf. Nice spots with grass between," notes a Casper East RV Park camper.
What you should know
Weather considerations: The Mills area experiences temperature swings and limited shade at some sites. "Nice fishing but the campsites can get very hot during the day...little to no shade in most campsites," warns a Gray Reef visitor.
Train noise: Some campgrounds experience railroad disruptions. "The only cons was it is close to the train which was a noisy when it came by, but didn't prevent us from sleeping," mentions a reviewer at River's Edge RV and Cabin Resort.
Primitive options: Several campgrounds offer more basic accommodations. "Deer Haven is a rustic haven for campers, boasting 11 reservable campsites and a single restroom. It's worth noting that water and utilities aren't accessible at this campground," explains a DeerHaven Campground visitor.
