I'm looking to take my family car camping this summer and just about all of the campsites are already booked through August. The remaining ones are first come first serve. Does anyone else find this pretty frustrating? I'm looking to find a place within a couple hours of Denver that will be available. Does anyone have any suggestions for go to stops that don't overflow. Appreciate any suggestions.

If you have an idea of where you want to go, search for a Motor Vehicle Use Map. The key shows you which roads have dispersed camping along them (ie dots along the road). There's lots of places up by Winter Park, Mt Evans, and Buena Vista to name a few which can help point you in the right direction
