This is one of two campgrounds in Rocky Mountain National Park that does not take reservations. It’s not open in winter. If you’re coming from Denver this is a very long drive (especially if you’re stopping to look around a bit) and you will most likely not get a walk-up spot in summer. There are more moose here than at the other campgrounds in the park. We’ve stayed in the C and D loops and both are amazing especially with bright yellow Aspen in the fall.
