Three Forks sits at the confluence of three major rivers—the Jefferson, Madison, and Gallatin—which form the headwaters of the Missouri River at an elevation of 4,075 feet. The area experiences cold winters with temperatures dropping below freezing, while summer brings warmer days often reaching the 80s with cool evenings. Camping options range from developed rv parks with full hookups to more primitive sites along the riverbanks.

Hike mountain trails: The Bridger Range offers excellent hiking opportunities, especially from Fairy Lake Campground. One visitor mentioned, "Great access to sacagewea peak hike and cold water," while another camper warned about access: "The 6-mile unmaintained road to get to the campground is definitely rough. The warnings are justified—it's bumpy, rocky, and slow going."
Fish multiple rivers: The Three Forks area provides access to four rivers with diverse fishing conditions. "If you like to fish you are in luck, you have four rivers to choose from, all with great fishing opportunities," states a Missouri Headwaters visitor. Many campgrounds offer direct river access, with some sites positioned along creek banks.

The tubs are great and super popular."

One visitor to Missouri Headwaters noted, "The campground itself is small but well-maintained, with both tent and RV spots. The real highlight is the location—you're right at the spot where the Jefferson, Madison, and Gallatin Rivers come together to form the Missouri River."
Clean facilities: Campgrounds throughout the region maintain well-kept facilities. At Lewis & Clark Caverns State Park, "Bathrooms were clean, showers were good- cost 50¢ per minute with a minimum of 6 minutes," according to Amy R.

What you should know
Weather considerations: Prepare for variable weather conditions. "Check weather report, strong winds and we had thunderstorms," warns a Lewis & Clark Caverns visitor. Summer evenings can still be chilly even when days are warm.
Mosquito activity: Campsites near water can have significant mosquito populations, especially at dusk. "When the sun sets in June and July the mosquitos will come out. They are quite nasty but an hour after sunset they are gone, having a campfire going helps too," advises Andreas W. about Missouri Headwaters State Park.
Reservation requirements: Many campgrounds fill quickly during peak season. At Ennis RV Village, advanced booking is recommended. Several campgrounds have limited first-come-first-serve sites, with Fairy Lake often reaching capacity early: "I would love to review this site but any time I've gone it's been full..boo."
Tips for camping with families
Playground options: Several campgrounds offer dedicated children's play areas. At Three Forks KOA Journey, facilities include "Super friendly staff. Sites are shady unless you have a big rig - that area does not have shade. Decent dog park. Decent playground," according to Maggie C.
Wildlife viewing opportunities: Children can enjoy observing local wildlife from safe distances. "The kids loved the playground and tons of open grass space and swings throughout, and they also have a pond that you can even fish him on site at the back of the property," reports Amber W. about Cardwell General Store and Campground.
Educational activities: Some parks offer ranger programs specifically for young visitors. "Did you know you can print out a packet for your little ones to become Cub Rangers at this State Park?" mentions Sierra V. about Lewis & Clark Caverns State Park.
Tips from RVers
Site leveling requirements: Some campgrounds have uneven sites requiring additional equipment. At Lewis & Clark Caverns, one RVer noted: "Had to use all our jack stands to combat the slope of our site (P007). Others looked much more level."
Access limitations: Not all rv parks near Three Forks, Montana accommodate larger rigs. One camper at Cardwell General Store and Campground shared: "I did not realize that I booked partial hookups! So for the price of $75 per night I do find it on the pricey side. They do have a dump station on site though."
Arrival timing: Most rv parks in the Three Forks area have specific check-in windows. At Three Forks KOA Journey, "Got in late (after 9), but they where nice enough to give us a tent site to camp in." Another camper mentioned, "The gate closes at 10. Check-in ends at 9p.m."
