Reviews Summary

Visitors rave about the stunning lake views and direct access to Flathead Lake at Big Arm Campground, with many appreciating the amenities and overall pleasant atmosphere. However, some campers have noted issues with uneven campsite terrain, which can be challenging for larger RVs. The popularity means booking far in advance is essential.

"Most of the sites are parallel with the lake shore so pretty easy to set up our trailer. Beautiful view. I did notice some bigger rigs with slide outs weren't able to extend them fully because your site is basically a wide spot on the road ."

Joe Stephens

"The camp ground views and water were AMAZING! The only reason it's not a 5 star is the camp site condition. We pulled our littlebpop up camper. The site was so uneven, our stabilizer jacks broke. It was pretty scary. I understand it's tough, but we would have appreciated knowing the condition of the terrain. Or the site should not have been listed as appropriate for a camper."

"I’ve been to Flathead many times and have never been to this side. We usually go to Wayfarer’s, but we missed the booking window this year. So we came to Big Arm and I was so pleasantly impressed with the amenities and the campsites. Really lovely place!"
