We camped in Moraine Park Campground last summer & absolutely loved it! One side (Loop C) of the campground has gorgeous views of the mountains & on the other side (Loop A) is an area for elk crossing at night. Right outside the campground is a popular elk viewing area at dusk - which can be congested with cars. The campground is also super accessible! It’s a short drive from the major hikes, the famous Trail Ridge Road, as well as the city of Estes Park. The RV sites offer no hook ups however, there are several water spoutd, bathrooms, bear boxes, & large garbage bins. Some spots are challenging to back into, but not impossible. You are unable to bring in your own firewood.
