Appalachian Trail - PA 309 to Lehigh Gap is a 13.5 mile moderately trafficked point-to-point trail located near Andreas, Pennsylvania that features beautiful wild flowers and is rated as difficult. The trail offers a number of activity options and is accessible from March until October.
This challenging section of trail will require you to navigate over and around car sized boulders. This section of trail runs along the top of the ridge. There are plenty of fantastic views, two shelters, and multiple campsites that aren't listed on the map. You'll also get to hike over the Lehigh Tunnel, but it's hard to know when you're actually over it. This is a rugged section of trail with a lot of boulders to navigate over.
My brother and I took our three boys on the trail Sunday for an overnight hike/camp. We camped overnight at the New Tripoli campsite. There are about 8 satellite sites there and the spring is running at the bottom of the site trail.
This was a very challenging section of the trail. We did it over 2 days with two young boys. One big drawback was the fact that the springs were dried up at the Bake Oven Knob shelter. Lots of great overlooks.
Great overnight trip...if you bring your own water. Hiked from 309 to the Bake Oven Knob shelter and back. This hike would easily have been 5 stars if the springs at the Bake Oven Knob shelter weren't dried up. We brought 70oz. hydration bladders planning to refill at the springs. All 3 springs at the shelter were bone dry. At this point there are still roughly 7mi. left to the Leigh gap so we were forced to turn back immediately to locate water for the night. Thankfully I had brought germicidal tablets and we were able to scoop enough water out of some tire ruts to fill our 2 bladders. This enabled us to stay out overnight and then trek back in the morning a short distance to water. All in all a fun hike/climb. The rock ridge is a difficult feature and I would suggest not attempting if you have any fear of heights and or are not confident in your balance.
