The upper echo bay NPS campground is only one small loop now, the others are all closed down and mothballed. There are only a few sites large enough for RVs and TTs though. No full hookups. Cost is $20/$10 senior, cashless now, need to either reserve beforehand or pay online onsite. Dumpsters, and a restroom. Cell signal is good at the upper cg, not so good at the lower cg. The lower cg is more suited for car truck and van campers. The marina has a small mini mart. There is a free RV dump here and also water spigots and trash dumpsters.
