The Upper Missouri River Breaks National Monument dominates the camping landscape near Hilger, Montana. Most tent campsites in this region require water access, though seasonal variations in river levels affect campsite availability. Summer temperatures regularly exceed 90°F while spring brings unpredictable conditions with potential for flash flooding along the Missouri River corridor.
What to do
Paddle to historical sites: Access Lewis and Clark's May 27, 1805 campsite via McGarry Bar Primitive Boat Camp. "Follow the trail to the marker" a few hundred yards downstream from the campsite, advises one camper. The historical marker provides context for this significant expedition stop.
Fish remote waters: The isolation of Yellow Water Reservoir offers uncrowded fishing opportunities. "Fishing can be good" notes a visitor, though success varies seasonally. Bring all necessary tackle and supplies as no facilities exist on site.
Set up hammocks: Mature cottonwood trees at riverside campsites provide ideal hammock supports. At Lower Woodhawk Campground, a camper notes there are "good spots to use a hammock" among the shady trees, offering relief from summer heat.
What campers like
Natural shade coverage: The cottonwood canopy at riverside campsites creates comfortable camping even during hot months. Visitors to Gist Bottom Primitive Boat Camp appreciate that "large cottonwoods give plenty of shade from the sun," making midday temperatures more bearable.
Multiple established tent sites: Several river camps offer clearly defined areas for pitching tents. One camper reports Gist Bottom features "great camp spots" with "plenty of bare ground" surrounding the fire rings, allowing groups to spread out comfortably.
Complete isolation: For those seeking true solitude, Yellow Water Reservoir delivers an unfiltered wilderness experience. A camper describes it as "about as close to desolate and isolated as your going to find," with expansive views and minimal signs of human presence.
What you should know
Difficult navigation: Finding river campsites requires careful planning and preferably GPS coordinates. At Lower Woodhawk, a camper warns the site "would be easy to miss" since you "can't see the campground from the river due to all the willow and the sign is missing." Look for small indicators like flags tied to vegetation.
Road conditions vary: Access roads to camping areas may become impassable during wet weather. The Lower Woodhawk site access road presents challenges as "entry and exit by road will not be possible during wet conditions."
Limited signage: Most tent campsites near Hilger, Montana lack obvious markings. A McGarry Bar visitor notes "the location can be a challenge to find as the sign can't be seen from the river" with only a "small take out location" indicating where to land.
Tips for camping with families
Pack abundant water: No drinking water exists at any tent campsites in the area. Calculate at least 1 gallon per person per day, plus additional water for cooking and cleaning.
Consider river mile markers: When planning a multi-day float trip with children, use river miles to schedule appropriate daily distances. McGarry Bar is located "at river mile 103.1" while Gist Bottom sits at "river mile 122.6," allowing families to plan reasonable daily paddling distances.
Prepare for facility variations: Facilities differ dramatically between sites. Lower Woodhawk has "two metal fire rings, 1 concrete picnic table... and one vault toilet" while more primitive sites offer minimal infrastructure. Adjust expectations and packing lists accordingly.
Tips from RVers
Trailer access limitations: The approach to Yellow Water Reservoir presents significant challenges for towed vehicles. The access road is described as "nothing more than a large trail," requiring high-clearance vehicles and careful driving even in dry conditions.
No hookup options: None of the tent campsites near Hilger provide water, electric, or sewer connections. RVers must be fully self-contained and prepared for primitive camping without service access.
