Incredible views. Fairly easy climb but calculated. So many horror story reviews I believe are from the inexperienced. I'm 5ft tall and did it with a 45lb pack on no problem. Heartbreaking to walk past superfund site but there were workers surveying and planting so hope is still there.

My friend and I did Smith gap to BlueMountain Drive several months ago. It was a good hike with the boulders at the end providing a bit of a challenge. Yesterday we attempted little gap to BlueMountain Drive. We found the boulder climbing in the beginning to be strenuous to the point of dangerous. Later as we approached the end of the hike we hit a power line cut and lost the white blazes. We ended descending through the power cut which was full of loose rock, boulders and many sticker bushes. We ended up on route 946. It was quite an adventure and we're happy to have survived.

Beautiful views, awesome hike with some climb included! Be ready to use your hands. It is totally rewarded. You won't regret it!

Great experience! we took one of the suggested routes from this app. Lots of fun! Many of the people hiking with me were beginners and still completed the hike without any problems.

I have hiked this area a bunch of times. Views are exceptional (bring camera and binoculars) and good footwear. Climbing the rocks feels great. I like this spot because I can do a long hike or a short 3 mile circuit. I start at the lot hike up the rocks and then hike in to the junction with the Winter Trail that brings you down the mountain on another trail that isn't so rocky. I took my 11 yr old son up there this past weekend and he loved the challenge of climbing up and over some rocks. We spent some time near the top going off trail a bit and climbing more rocks.... I've hiked this in a few variations. Just up to the top and then loop back down the winter trail for a quick workout or pressed on to the Blue Mtn Drive for a pickup or even further to Smith Gap Road, all in one day. I am posting some pictures of the various hikes in this area.

Nice section of the AT. A little tough climbing out of the gap but the views make it worthwhile. Great opportunity to get a concrete exaple of the environmental impacts of pollution when passing through the superfund site.

AlD review is accurate. It take 2 hours going north to reach the road of Blue Mountain , north of Danielsville, that is the surprising part with surprising landscape and a great view along the trail. So if you do not want climb it, you can park near Blue Mountain and walk south. I noticed there is no white marks on the trail on top. The second part going from Blue Mountain to Smith Gap rd is another 3.5 hours in the wood with a few points of view. The hike is more difficult.
