RV Parks In Big Timber, Montana

Yes, and they're your best bet for services. Spring Creek Campground & Trout Ranch sits on the Boulder River about 5 miles south of town and offers 50-amp full-hookup pull-through sites along with riverside electric-and-water sites, a dump station, laundry, a store, and free showers. The Big Timber / Greycliff KOA Journey is parked right off I-90 at the Greycliff exit with 50/30-amp full-hookup pull-throughs that make for an easy overnight. Beyond those two private parks, most camping in the area is public and basic, with no hookups, so if you need power, water, and sewer at the site, plan to stay at one of these. Both take reservations, and we'd book a few weeks ahead for the summer months.

Big rigs do fine in the right spots and poorly in the wrong ones. Spring Creek and the Greycliff KOA both sit just off good paved roads near I-90, with level gravel pull-throughs that handle 40-footers without trouble, so base there if you're long. The catch is the Boulder River valley. MT-298 is paved only for the first few miles, then turns to narrow gravel, and the Custer Gallatin forest campgrounds 25 to 33 miles up enforce a hard 32-foot vehicle limit with no turnarounds. Grey Bear fishing access also caps vehicles at 32 feet. So if you're running a large rig, stay near town and day-trip the canyon in your tow vehicle rather than dragging the trailer up the valley.

There are several, all public and rustic. Up the Main Boulder Road in the Custer Gallatin National Forest, Big Beaver (5 sites) and Falls Creek (8 sites, tent-only) are free and first-come, first-served, with vault toilets and no hookups or guaranteed water. Along the Yellowstone River, Montana FWP fishing access sites like Otter Creek are free or carry only a small fee, with primitive riverside camping, a vault or pit toilet, and no power or water. The trade-off for free is minimal facilities and, in the forest, a 32-foot vehicle limit. These work great for self-contained smaller rigs and tent campers, but bring your own water and plan to be fully self-sufficient during your stay.

It depends on where you're staying. The private parks, Spring Creek and the Greycliff KOA, take reservations through their own booking systems, and we'd reserve a few weeks out for July and August when Yellowstone traffic is heavy. Cooney State Park accepts reservations through Montana State Parks up to six months in advance and fills on summer weekends, so book early there too. The public first-come sites, including the Custer Gallatin forest campgrounds and the FWP fishing access sites, can't be reserved, so arrive early on weekends to claim a spot. As a rule, lock in the hookup sites ahead and treat the free public spots as a roll of the dice on busy weekends.

Summer is the clear high season, running roughly June through September with warm days, cool nights, the best fishing, and steady Yellowstone-bound traffic. Spring is variable and muddy, with river runoff and snow that lingers up the Boulder valley into May, so lower-elevation sites open first. Fall brings golden cottonwoods and thinner crowds, but nights cool off fast and the Boulder River road gets snow-limited as the season closes. Winter is cold and quiet; Spring Creek stays open year-round while the KOA closes, and most mountain roads and public campgrounds are snowed in or shut to vehicles. For full-service camping with everything open, aim for late June through early September.

Montana FWP fishing access sites are the main option, and they're aimed at anglers and floaters. Grey Bear, about 5 miles west of town off I-90 exit 367, allows camp trailers up to 32 feet, has a vault toilet and no water, charges a small fee, and limits stays to 7 days. Otter Creek, north of town, offers free primitive camping with open fields and shaded riverside spots, a pit toilet, and no hookups. These are basic by design, so come fully self-contained with your own water. They put you right on one of the best trout rivers in the country, which is the whole point. Confirm current FWP access status before relying on a boat ramp, since some were under construction in spring 2026.

Yes, Cooney is the best public option in the area for RVers who want some amenities. The park sits on Cooney Reservoir southwest of Big Timber toward Roberts and has 82 campsites across five campgrounds, including 19 sites with electric hookups. You'll find drinking water, flush and vault toilets, coin-operated showers, a fish-cleaning station, a playground, and boat ramps. Fishing is solid for walleye and rainbow trout, and boating is popular in summer. Reservations run through Montana State Parks up to six months ahead, and electric sites cost around $36.50 a night while standard sites run cheaper. It's a reservoir park rather than a riverside one, so check individual site lengths if you're in a larger rig before you book.

Plenty, and most of it is outdoors. Fly fishing is the headline act, both on the Yellowstone River running through town and on the Boulder River up MT-298, with multiple public access sites. Natural Bridge Falls, about 26 miles south, is a Custer Gallatin day-use area where the Boulder River drops through a rock formation, with short trails and overlooks. The Crazy Mountains rise dramatically to the north for hiking and photography, and the Boulder valley is the local gateway into the Absaroka-Beartooth Wilderness. Closer in, Greycliff Prairie Dog Town State Park east of town is a quick, kid-friendly stop. Big Timber also works as a quieter basecamp for a Yellowstone National Park day trip through Paradise Valley.

It's roughly a 2.5-hour drive to Yellowstone's north entrance at Gardiner, heading west on I-90 to Livingston and then south down Paradise Valley along US-89. That makes Big Timber a workable basecamp if you want to avoid the crowds and higher prices in the gateway towns right at the park boundary. We'd leave the RV set up at Spring Creek or the Greycliff KOA and make the run to the park in your tow vehicle, since hauling a big rig that distance for a day trip burns fuel and patience. Plan a full day, get an early start, and remember that summer is peak traffic both on the highway and at the park entrance. It's a longer commute than staying in Gardiner, but the savings and quiet often make up for it.

Big Timber is a small town, so plan around it. You'll find basic groceries, fuel, and propane in town, and Spring Creek Campground has a store and an on-site dump station. For anything beyond the basics, including RV repair, parts, and big-box restocking, your real hubs are Livingston about 33 miles west, Bozeman about 60 miles west, and Billings about 80 miles east. The big lesson is to top off fuel, propane, water, and groceries before you head up the Boulder River road, because there are no services past Spring Creek and the valley gets remote fast. If something breaks on your rig, plan on a trip to Bozeman or Billings, where the dealers and parts stores are.

Not really, unless you're after solitude and you're prepared for cold. Winters here are genuinely cold, with daytime highs often in the 30s and overnight lows in the teens or below, and the mountain roads up the Boulder valley are snowed in. Among the local options, Spring Creek Campground stays open year-round, while the Greycliff KOA and most public campgrounds close for the season. If you do camp in winter, you'll want a four-season rig with skirting, heated tanks or careful tank management, and a backup heat plan. The fishing access sites and forest campgrounds are effectively off-limits to vehicles. For most RVers, Big Timber is a late-spring-through-fall destination, with summer being the clear sweet spot for weather and open services.

The main artery is I-90, which runs east-west straight through town with two exits and connects you to Billings to the east and Bozeman and Livingston to the west. It's an easy interstate for any size rig, and both private parks sit within a couple of minutes of it. US-191 heads south from the area toward the Boulder country and eventually Gardiner. The route that demands attention is MT-298, also called the Main Boulder Road or County Road 212, which follows the Boulder River south into the mountains. It's paved for the first several miles, then turns to narrow gravel with a 32-foot vehicle limit at the forest campgrounds. Stick to I-90 and the lower Boulder road with a big rig, and use a tow vehicle for the upper valley.

Yes, this is dog-friendly country, with the usual rules. The private parks, Spring Creek and the Greycliff KOA, welcome pets, and you'll want to keep them leashed and clean up around the sites. On public land, Montana State Parks like Cooney and FWP fishing access sites allow leashed dogs, and the Custer Gallatin National Forest is generally open to dogs on trails and in campgrounds. At Greycliff Prairie Dog Town State Park, pets are allowed but must stay leashed, and you'll want to keep them well away from the prairie dog burrows. Carry water for your dog on hot summer days, watch for wildlife and snakes in the grass and rocks, and remember that this is bear and big-game country, so don't leave food or pets unattended outside.
