Nearby Whitefish, MT has a growing reputation for fantastic trails, hikes and mountain bike areas, and this full-service oasis takes advantage of all of it.  The $50 per night fee (for the tent sites) comes with a sauna, bike repair and washing station, gift shop, hot showers, laundry, wi-fi, a bike skills area, trails for all levels…all intertwined with the Beaver Lake series of trails and small lakes.  Very kid and pet friendly, a community-building locale.  There's a large lodge for people wanting a roof over their heads.  As another example, if you bike in, they would usually try to make space for you (even if everything was full) and charge $15.  Plus, there are bike trails/easy routes to every other major biking area around Whitefish - Spencer Mountain, Lyon Mountain, Reservoir Lake and Big Mountain Nordic.  I could be nit-picky and say that the camping sites are a little on the small side and crammed together, but there's personality to each one and to the area in general.  Word of caution - reserve in advance!  😯  There was only one campground left on a Sunday evening in June.  The friendly attendant said they can make some exceptions for large groups.
