Big Timber-Greycliff KOA

Families with active kids will find plenty to keep everyone busy at Big Timber-Greycliff KOA, where a large jumping pillow, heated pool, and creek running along one side create natural entertainment zones. The campground sits close to Highway 10, making it easily accessible for travelers but also generating consistent road noise throughout the day and night.

The gravel RV pads run narrow, requiring careful maneuvering for larger rigs, while tent sites offer electric and water hookups. "Little creek runs alone one side, tall pine trees…just a nice feel to the campground," notes Kathy D.. Train tracks border the property, though overnight train traffic appears minimal according to camper reports. Sites closest to the highway experience the most noise, while back-in spots toward the rear offer more separation from traffic sounds.

The facility maintains clean restrooms and showers with strong water pressure and reliable hot water. A small enclosed dog run accommodates pets, and the camp store stocks basic supplies. Raspberry bushes near the pool and chokecherry trees throughout the grounds provide seasonal foraging opportunities for campers interested in wild edibles. The creek offers a place for kids to play and explore, adding to the family-friendly atmosphere.

Staff responds quickly to requests, bringing additional picnic tables and fire rings when available, though some campers report theft issues with these items. The campground operates seasonally from mid-May through early September. Prairie Dog Town State Park sits within walking distance, offering wildlife viewing opportunities. For those seeking additional overnight options in the region, campsites near Greycliff provide alternatives for travelers exploring south-central Montana.

The combination of highway convenience and family amenities makes this KOA work best for overnight stops and families with children who enjoy pools and outdoor play areas.

Numerous guests pointed out friendly staff and great family amenities like the jumping pillow and pool. However, consistent concerns about highway and train noise affect the experience for most visitors.

Highways & Railroad noise!

Visitors & staff are so friendly & helpful! Nice pad, good water & electric access, small park but close to river walk which was also nice. Only complaint is the sites are backed right up to the Highway. Would serve the park to build a wall or even just a tall wooden fence to help cover some of the road noise.

Small KOA

Typical KOA with those amenities. Sites are close together as usual at a KOA. Pads are gravel and super narrow. Lots of kids having a blast at the pool, riding their bikes and playing in the creek that borders the campground. Dog park is adequate though small. Staff is nice and responsive. We did not have a picnic table at our site and they quickly brought one when I asked. They said people were stealing them as well as the fire rings. A bit odd that someone would steal a wooden and metal frame picnic table? We gave our fire ring to the family next to us as we weren’t going to use it and the office told them they didn’t have any extra.

Giving 3 stars due to the proximity of the highway (you can definitely hear the traffic) and train tracks (no train overnight though) as well as the odd picnic table issue and the narrowness of the pads. But if you have children they will most likely love this place.

Spacious and Clean

Very nice ladies at the office/store. Little creek runs alone one side, tall pine trees…just a nice feel to the campground. The showers had plenty of hot water and great water pressure. It was nice that they have a little off leash enclosed dog run. Just right for our 1 year old puppy. Saw kids enjoying the huge bouncy “platform”. We have this on the list to come back if we journey this way again.

Siteit was a tent site…I don’t remember the number.

Train and road noise

This campground was right off the interstate and close to the tracks. We went to go park and our site was occupied. They did accommodate us in an overflow spot near long term. They have a bounce pad for the kiddos, must have measured 20ft x 50ft.

Enjoyed the cabin

We upgraded from a tent site to a cabin because there was a storm coming through as we were driving. We enjoyed the cabin quite a bit, and we'll do it again. We love the campground, but the traffic noise and occasional trains were quite irritating

Great place to camp!

This was our families first stay at a KOA. We really enjoyed our time. We tent camped. We had electric and water at our site, and we were just a short walk to an inflatable trampoline, a heated pool, the camp store, showers, restrooms, and laundry facilities. The staff were very helpful with anything we needed. Great campground to stay at!

Nice KOA

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 sites were bigger than most other KOAs, yet still boasted the great amenities. There was a nice playground, pool, enormous jumping pillow (I had never seen one before - this was definitely a treat, even for adults!) and a small dog run area. Great WIFI and AT&T coverage. We would definitely stay here again on our way through town.

Be sure to stop by at Prairie Dog Town State Park (walkable distance from campground). It’s simple but a cute place to watch prairie dogs and check out the local flora.

Meh

Upside: friendly, family oriented Downside: spaces very close together, bathrooms were worn, no propane fill (exchange only), and noisy from highway and trains ( which I know the owners can’t control)

Very practical - Right off the highway

Ok like the last reviewer we could not find a site in and around the Bozeman area and were headed east anyway so we call this site and finally was able to get a spot. It was really just a place to sleep for the night for us - not much to see unless you head over to the river. Sort of noisy so close to the highway so I’d ask for a back-in spot because those are somewhat more secluded and off the road. Clean bathrooms and cute shop in the office.

A refreshing oasis amidst a turmoil

We came up thru the Rockies and Yellowstone with no available camp sites and it was getting late and we found a space here. We were originally planning on staying one night but stayed 3. The staff was so friendly and attentive. The bathrooms and showers were clean. The pool was nice and refreshing. There are raspberries bushes around the pool that you can pick. We made raspberry jam on the fire. Chokecherry trees surround the camp grounds that can also be picked. There’s a stream that runs around the back. While you stay check out natural bridge falls only 30 minutes away. Tent site was about 37 a night.

Noisy

This campground is really nice like most KOA's, but it is backed up to the interstate which makes it pretty noisy throughout the night. The showers were nice as well as most everything else about the grounds. It did seem like I was never going to reach the campground as I came in on Old Hwy 10 from the west. It's better to exit off the interstate just east of the campground.
