Stayed a Saturday night at the Estes Park East Portal campground. We brought out 22ft RV and it fit the site perfectly. Anything larger will be difficult to navigate. The park is very conveniently located near Estes Park and Rocky Mountain National Park. They have nice sites although some are small and very close to one another. They have clean bathrooms with showers and even have a playground. We had no cell service nor is there any wifi. We took the east portal trail which is a beautiful hike and goes near the reservoir. Nice place to camp!
