We have stayed at Doris 2 or 3 times over the last few years. It’s a large site with over 60 campsites that are fairly well spaced out. Separate RV/powered locations from drive up and walk in campsites.
Lot’s of great activities in the area: hiking, climbing, fishing, wildlife and other options.
My primary complaint of Doris is that it get’s rowdy on the weekends. On our most recent trip a group of locals pulled in at about 10pm and partied until after 2am then left. They were not camping at all.
