Campsites near Melville, Montana provide access to both the Boulder and Yellowstone River corridors at elevations ranging from 3,800 to 5,000 feet. The region experiences significant temperature variations with summer highs reaching 90°F and overnight lows dropping to 40°F even in July. Most camping areas open from late April through early October, with fishing access sites typically maintaining longer seasons than mountain locations.
What to do
Fishing the Boulder River: Located just 3 miles from Big Timber, Otter Creek Fishing Access Site offers direct river access for anglers. "Beautiful views and quiet. Nice to have a small stone fire ring on the River," notes Susan W., highlighting the primitive but scenic setting. The area provides excellent opportunities for catching trout throughout summer months.
Hiking to alpine lakes: The Crazy Mountains provide challenging day hikes from Halfmoon Campground. "I hiked to Granite Lake (4mi) and it was hard but worth the effort for sure," shares Brodie B. The trailhead adjacent to the campground connects to several routes leading to mountain lakes and viewpoints, with most hikes requiring moderate to strenuous effort.
Trout fishing ponds: For families wanting guaranteed fishing success, Spring Creek Campground & Trout Ranch maintains stocked ponds. "They also stock the ponds with trout so that for dinner you can eat fish. They also clean the fish for you," explains Lillie D. The ranch charges a daily fee for fishing access but provides equipment rentals and cleaning services.
What campers like
Riverside sleeping: Camping directly alongside the Yellowstone River ranks as the top experience for many visitors. "Going to sleep with sound of Rushing Water 20 ft away from me. Good cell reception on T-Mobile but no trash, water or power hookups," reports Steve M. about his stay at Otter Creek Fishing Access.
Mountain seclusion: The higher elevation sites provide cooler temperatures and forest surroundings. "Nestled at the base of the soaring peaks of the Crazy Mountain Range, Halfmoon Campground feels truly magical. The dozen campsites are spread amongst the tall pine forest," describes Aspen K. The campground sits at approximately 5,000 feet elevation, offering relief from summer heat.
Budget-friendly options: Most fishing access sites along the Yellowstone River corridor offer free or low-cost camping. "Free spot on the Yellowstone close to Big Timber. Fast and high water in June. Not much to do at this spot but it's free. One vault toilet," notes reviewer Kyla about Otter Creek Fishing Access Site. Many sites operate on a first-come basis with no reservation requirements.
What you should know
Road conditions: Access to mountain campgrounds requires preparation and appropriate vehicles. "Road in is gravel for about 16 miles with the last 4 having vehicle crawl. If you go more than 10 miles an hour in this section you will probably pop a tire and should definitely have 4x4 and high clearance," warns Callie B. about accessing Halfmoon Campground.
Limited amenities: Most fishing access sites provide only basic facilities. "No amenities except a pit toilet but beautiful views and quiet," reports Susan W. about Otter Creek. Similarly, at Grey Bear, visitors note "vault toilet...no water...no trash" but appreciate the riverside setting and shade from cottonwood trees.
Seasonal availability: Mountain locations have significantly shorter seasons. "We woke up to the craziest wind storm around 1am!!! Our tent took quite a beating, we are estimating that winds were above 50mph!!!" shares Rachel S. about conditions at Halfmoon Campground. Weather at higher elevations can change rapidly, with mountain sites often experiencing snow by late September.
Tips for camping with families
Playground access: For families wanting developed facilities, Chief Joseph City Park in Harlowton provides a mix of camping and recreation. "This is one of the nicest small town parks I have ever experienced. The play area for children is five star. Rodeo grounds, volleyball net, soccer field are just a short walk from the campsites," notes Denise W.
Swimming spots: The Boulder River offers several areas with slower currents suitable for supervised swimming. "Lots of river running through the campground and low enough to enjoy a swim, fish, or get your feet wet," mentions Robert B. about Big Rock fishing access. These locations typically feature gradual entry points with shallow water areas.
Wildlife viewing: Bring binoculars for spotting local wildlife. "Black bear and Moose are frequent visitors," advises Connie H. regarding Halfmoon Campground. Prairie Dog Town State Park near Big Timber offers another viewing opportunity within walking distance of some campgrounds, where kids can observe prairie dog colonies.
Tips from RVers
Length limitations: Most fishing access sites accommodate smaller RVs but have size restrictions. "Room for 5 or 6 big rigs and several tents, depending on how they are parked. There is an outhouse. Access is easy but a bit rough so go slow," advises Jeff & Alison H. regarding their experience at Otter Creek Fishing Access Site.
Hookup availability: Full-service options exist but are limited to private campgrounds. "Clean bathrooms and showers along the river," notes Mike about Spring Creek Campground & Trout Ranch, one of the few locations offering water, electric, and sewer connections for RVs in the immediate area.
Electrical-only options: Several municipal campgrounds provide electrical hookups without water or sewer. "Great small town RV park. $20.00 per night with electric. No sewer or dump station. Water on site but not to RV pads. Level, asphalt pads are all pull-through and long enough for my truck and 32 foot 5th wheel," explains Bradley H. about his stay at Chief Joseph City Park.
