Big Timber-Greycliff KOA accommodates pets with a designated dog park area where dogs can exercise off-leash, though some visitors note it's adequate but small in size. The campground features tent sites, RV spots with full hookups, and pet-friendly cabins that can be reserved in advance. Guests camping with dogs particularly appreciate the grassy areas between sites that provide space for pet walking. Located just off Interstate 90, the campground experiences some road and train noise that pet owners should consider when planning their stay. Pets must be leashed when not in the dog park, and the camp staff enforces pet waste cleanup throughout the grounds.
Fishing access sites around Greycliff offer more primitive pet-friendly campgrounds for those seeking a nature experience with their dogs. Big Rock Fishing Access Site and Pelican Fishing Access Site both permit pets and provide more spacious, less developed camping areas along the Yellowstone River. These sites typically feature vault toilets and fire rings but lack amenities like running water or electric hookups. Visitors should be aware of wildlife presence in these areas, as some campers have reported deer sightings and occasional mentions of bears. During summer months, the riverside locations offer opportunities for dogs to cool off in the water, though limited shade at some sites can make hot days challenging for pets. Campers should pack enough water for themselves and their dogs when visiting these more remote locations.
"Great dispersed camping beside the Yellowstone River just off Interstate 90 near Big Timber, Montana."
"This is a free Montana Fishing Access Site next to the Yellowstone River north of Big Timber. There was one clean single vault toilet for about 5 sites."
"We also noticed that from staying here in September 2019, the ponds are now state-stocked, and you need a Montana fishing license following regular fishing regulations versus no-license pay for the trout"
"They are kind to kids and pets as well. I spent my time doing this full time and people that run campgrounds don't always have the most respect for dogs or kids. Spent 30 days here."
"Grear trees, shade, tables, grass, pet area, nice staff. Close to hwy but we will return"
"Usually we stay at KOAs for stopover convenience, but being tired of driving we decided to stick around for an extra night. For a KOA, this was a really decent spot."
"The location is hard to beat. Being right by the stream adds such a peaceful touch, and the sunsets and sunrises here are truly beautiful. Waking up to that kind of view is something special."
"Awesome location, 10 minutes from the expressway and on the river. About a half dozen sites with a pit toilet that was stocked and clean. "
"Very nice campground about 6 miles out of Big Timber Montana."
"There are trains close by but that didn't bother too much. If you stay with kids there are spots where the river current is quite strong close to shore."
"Family and pet friendly. Large campsites each with a picnic table and fire pit. Public toilets non-threaded water spigot near the entrance."
"Close to the Yellowstone. We camped on the second loop and at the end near the boat dock is a trail that follows the river. We enjoyed the walk with our dogs. Lots of folks fishing."
"There is noise from the I90 and you can see straight to the highway but still nice nonetheless."
"He welcomed us warmly and mentioned the$10 one-time pet fee, which we hadn't noticed when we booked(it was a while ago)."

ScoutIt is no longer Red Lodge rv park now Alpine Lodge Rv Park there are 6 level site adjacent to the lodge
LegendOne night at a spot with water and electric off season is $80. Just about turned back around and kept driving. I know, KOA is costly. The upside, nice showers, laundry. Nice enough spot in the shade which is great since it is very hot today.
GuideFreeway visible and audible from site. Active railroad nearby. However, campground clean, vault toilet stalled with toilet paper, river front camping. Easy access from highway. Required state conservation license for use.
RangerLong and to bad road you can pull off an set up. Not a ton of shade but the river is right behind you. Amazing veiws, good cell signal. Spent 2 days, awesome little spot.
ScoutThere’s not many spots and there were about 5 groups already here. Not much privacy but very pretty my the river.
RangerWe needed a good spot for an overnight stop between Mt Rushmore and Yellowstone… And, Itch Kep Pe City Park was the perfect place. Scenic, quiet and free! We did put a donation in the drop box though. Would have wet a fishing line if I had more time!
LegendVault toilets, fire pits, tables, right on the river. Great spot.
ScoutRoad is bumpy the farther in you go. Lots of nice dispersed sites near water. You can walk up and down the Boulder. Great for fishing farther in.
The Yellowstone River winds through Greycliff, creating numerous fishing access sites that double as pet-friendly camping areas. Most campgrounds in the region sit at elevations of 3,800-4,200 feet, with summer temperatures typically reaching the mid-80s during day and dropping to 50s at night. Weather patterns can change quickly in this part of Montana, with afternoon thunderstorms common in summer months.

The campground also offers stocked ponds where "kids got to feed fish in the pond just stop in and ask for the food," according to Christyn T.
River recreation: The Yellowstone River provides cooling relief during hot summer days at Grey Bear fishing access site. "Camping and fishing on the Yellowstone river. Fun for the kids and only a few miles from town to get supplies," notes Taylor L. However, some spots require caution as "there are spots where the river current is quite strong close to shore," warns Rick H.
Hiking trails: Just outside Big Timber, forest service land offers hiking opportunities. Near East Boulder Campground, "the trailhead for the Green Mountain Trail, a very nice 6 mile hike to the Natural Bridge, is across the road," shares Rob F., making this a good base camp for day hikes with your dog.
Riverside sites: Many dog-friendly campgrounds near Greycliff feature premium riverside camping spots. At Otter Creek Fishing Access Site, campers appreciate the natural setting. "Nice to have a small stone fire ring on the River. No amenities except a pit toilet but beautiful views and quiet," notes Susan W.
Shade coverage: The intense Montana summer sun makes shade a valuable commodity. Itch-Kep-Pe Park offers "nice level spots. The campsite is right on the Yellowstone river," according to Troy M., who adds it's "free but they do have a donation box." Another camper mentions the park has "well laid out camp spots. You aren't on top of each other. Nice trees, shade, grassy areas."

One camper received "a handy little poop bag holder with a built-in flashlight—a fun and useful touch for dog owners." The park's walkable location means convenient pet outings.
Noise considerations: Highway and train noise affects several campgrounds in the region. At Big Rock, the primitive setting offers natural quiet, though sites fill quickly. "Lovely little spot! Showed up around 5pm Friday and there was only 1 other camper. Had a third join by the end of the night but was super quiet the entire time," reports Abby M.
Limited amenities: Most fishing access sites have basic facilities only. "Vault toilet was clean and well stocked. 6 sites with rock fire rings. A couple sites had picnic tables too!" notes one camper about Big Rock. Pack sufficient water and supplies as most sites lack running water.
Wildlife awareness: Deer are common throughout the area's campgrounds. At East Boulder Campground, visitors report "lots of deer in the area!" Keep food secured as "some campers have mentioned seeing a grizzly every once in a while so keep items secured!"
Swimming spots: Children can enjoy cooling off in shallow sections of the Yellowstone at several fishing access sites. At Grey Bear, parents appreciate the "shady campground" that provides relief from summer heat while kids play in the water.

Site sizes and access: RV sites vary significantly between established campgrounds and fishing access sites. At Otter Creek, one RVer notes there are "about 5 sites and then 3/4 tent sites with rings. Some people parked in the field to camp so I guess that works too."
Hookup availability: Full hookups can be found at private campgrounds like Old West RV Park. A visitor describes it as having "utility connections thoughtfully centered on the pad, making setup a breeze" and notes "water pressure was a solid 50 psi."
Connectivity options: Internet access varies by location. Old West RV Park offers "4 bars each on both Verizon and T-Mobile, and the CG Wi-Fi clocked in at 26.5 Mbps down and 11.9 Mbps up, pretty solid for a small CG."
