Visited Whitney Reservoir during the 2nd weekend of July. The wildflowers were showing off all over the place! The reservoir actually looked quite full to me, it was beautiful. From what I could gather, I was expecting this area to be much more crowded than it actually was. It was not nearly as busy as I thought. My husband and I arrived late Friday morning and got a great spot near the water. Neighbors were about 50- yards away but coudn't see them from camp. Much more private than a typical campground. The main road was manageable through 638 (the road we stayed on) but got bumpier after that. Pulled a 18' camper and some spots were pretty rough. But I saw bigger campers get to the same area so it's doable. By the way Google maps shows 638 as a loop. It was NOT a loop. Maybe if the water was lower it would have been. We had to make a tight turn around to go back up the steep hill. I imagine it would be tough with a much bigger camper. Caught tiger and rainbow trout from shore both evenings but the mosquitos are bad!! Be prepared with DEET and/or a ThermaCELL. We saw tons of wildlife, including a moose swimming in the lake (one of the perks staying by the water! ) Overall, if you're looking for a beautiful getaway, this might be it! No service for the most part except for random spots here and there (at&t).
