We stayed at Ohanapecosh a little bit by accident. We had originally intended our trip to be a large group and had only looked at group campsites, and when we went (August 2015) the Cougar Rock group campground in the Paradise area was closed. So we stayed on Ohanapecosh, and it was absolutely one of my favorite campgrounds from our entire trip- and we stayed in a LOT of campgrounds (13, to be exact). We had two sites for 8 people, E09 and E11, and it was the perfect amount. It wouldn't have felt strange if we had been in one site or the other with another group in the opposite site as they were reasonably spread out, but those two sites were definitely grouped together a little more than other sites. It was nice to not feel like the campsites were all right on top of each other! Our sites were incredibly beautiful; close to the river, with nothing but trees and nature between us and the water. We were far enough from the bathroom that we didn't get much foot traffic, but close enough to not be a hassle for the pregnant member of our group. :) Definitely a little hidden gem in Mount Rainier- even during the busy summer the campground was quiet and relaxed.
