There are hardly any camping spaces that are not in the shade. In fact the only part of the park that isn’t heavily wooded is the huge special event meadow, which is not for camping.
Do take a lot of mosquito repellant, though. They will bite any inch of skin you haven’t put it on. I hate spray, so I use the gel, but I do not recommend it, because I missed too many spots and suffered for it.
@YARNLADY : This is true. I used to live 5 min away from Rocky Gap and about 30 from Deep Creek. I’ve been to those places more times than I can count! They are enormous fun and beautiful, especially in the fall. I guess the west just seems more exotic to me since I’ve never been there. One of my “bucket list” entries is to hike in the Redwood and Sequoia forests. :) Also Sea World.
