Jim and Mary's RV Park in Wye, MT, about 12 miles north of Missoula on I-90 at the junction of Hwy 93, the gateway north to Flathead Lake, Columbia Falls, Whitefish, and Glacier NP. Been two years since we have been there, but they had live music once a week. Landscaping at every site with flowers everywhere. This is glamping; no golf carts, ATV's, dogs off leash, loud neighbors, or junky campers. Diesel within a mile (Flying J) and a great place for breakfast (Muralt's Travel Plaza).
If you can't get in to Jim & Mary's, there is always the Yogi Bear's Jellystone Park across the highway.
