Dispersed camping spots surround Custer Gallatin National Forest at elevations ranging from 5,000 to 8,000 feet, offering free overnight options within 30 minutes of Yellowstone National Park's northern and western entrances. The terrain varies dramatically from desert-like conditions near Gardiner to dense pine forest areas near West Yellowstone, with overnight temperatures frequently dropping below 40°F even in summer months.
What to do
Hike nearby trails: The Targhee Creek area provides access to a 13-mile trail system with seasonal wildflowers. "There's about 8 single spots in the beginning that are singles with fire pits. In the middle of the road there's a meadow that if you don't get lucky with a single spot you can park next to neighbors. The road ends at the creek," notes Nikki N.
Fishing access: Several dispersed sites offer direct water access for fishing. "Great fishing access! Stayed 8 nights, and only large issues we had were solar not having enough exposure and same sort of issue for our Starlink," reports a camper at Hyalite Canyon Dispersed.
Wildlife viewing: The area supports diverse wildlife including elk, deer, and bears. At Davis Creek Camp, one camper mentioned, "Awesome Mountain views. Camped here after visiting Yellowstone. The road up was really rough with chatterbumps and rough divots in the road for my truck and slide in camper."
What campers like
Proximity to Yellowstone: Most free camping areas near Custer Gallatin National Forest provide relatively quick access to park entrances. "15 minutes from the Mammoth Hotsprings visitor center. Easy to access, no crazy potholes or anything, just a dirt road," explains a camper at Travertine Road Dispersed.
Established camping spots: Many areas feature existing fire rings and cleared tent spots. "Five sites along a 4.5 mile dirt Forest Service road. These sites are large with trails that run to the river. If you're looking for a primitive and peaceful camp site, this place is beautiful," writes Kerrie L. about Beaver Creek Road.
Cell service availability: Contrary to expectations, several dispersed camping areas offer reasonable connectivity. "Excellent Verizon service was a bonus that we don't get at a lot of dispersed sites," notes a camper at Targhee Creek, while another camper at Hyalite Canyon mentions having sufficient service for basic needs.
What you should know
Road conditions vary significantly: Many access roads feature washboard surfaces and potholes. "The dirt road you have to drive on to access it is super bumpy due to many potholes and large rocks. This is likely no problem for a truck or suv but my sedan had a difficult time getting up the road," explains Jeremiah L. about Travertine Road.
Temperature fluctuations: Overnight temperatures can drop dramatically, even in summer. "It did rain the night we were there and we woke up to 34 degrees. That was shockingly cold for us Arizonans in August," reports a camper at Taylor Fork Road.
Limited availability on weekends: Most popular free camping areas fill quickly Friday through Sunday. "We came in Labor Day weekend at 6:30 pm and were able to get a spot," notes one camper, suggesting that even on busy weekends, late arrivals may find options, particularly at Little Trail Creek Road.
Tips for camping with families
Look for creek-side options: Sites near water provide natural entertainment for children. "We stayed in site 1, the first of three on the first loop. So far, the only thing we can hear are birds chirping, the flowing creek, and the sounds of our children squealing with delight as they play out in the grassy field," shares a family at Taylor Fork Road Dispersed.
Pack extra layers: Even summer nights require warm clothing. "The inside of the truck bed had frost in the morning (22°!)," reports a camper at Targhee Creek, highlighting the importance of proper cold-weather gear even during peak season.
Insect protection is essential: Several camping areas report significant insect activity. "The flies were unbearable despite using spray of all kinds. Night time was enjoyable when they went away but it was hard to enjoy while being attacked in the eyes and face," warns a camper at Targhee Creek.
Tips from RVers
RV site selection caution: Not all dispersed camping areas accommodate larger vehicles. "This location was almost impossible to get to, my father took his RV up the hill before we took ours up & his almost bottomed out. There's no way to know how bad that road is until you actually start driving up it," cautions Samantha D. about Little Trail Creek Road.
Leveling requirements: Many sites feature uneven terrain. "The sites themselves are spread out, we did not hear anyone. There is a rock fire ring and a very uneven parking spot - bring your levelers!" advises a camper at Beaver Creek Road, emphasizing the importance of proper leveling equipment.
Consider campground alternatives: During peak season when dispersed sites fill, nearby established campgrounds offer reliable alternatives. "Hood Creek Campground 5 miles further had ample spots including lakeside," notes a visitor to Hyalite Canyon, providing a backup option when free sites are unavailable.
