Dolly Sods is a wilderness area within the great Monongahela National Forest. I backpacked here in early March a few years ago. Definitely be prepared for high winds and rain. We hiked in in warm weather and once we reached the top of a long entrance road (where one trailhead was) we found snow. A lot of the snow had melted making the ground very soggy and oversaturated in some areas. Despite this, our short Dolly Sods backpacking trip was an amazing first trek for myself and a fiend. Dolly Sods is absolutely gorgeous and is a completely different and unique ecosystem than the surrounding area. I also have friends who have camped here later in the year - mid to late summer - and have highly, highly, recommended that I go back during that time.
