O the notorious Gorilla hill. You got a love it! This is like a half marathon with a little extra credit. Start at the sunken gardens parking lot gate for your start and finish. Once inside gate and eager to roll begin 13 consecutive over and back. Start with hand on gate and touching cable or pipe on other side before returning to sunken Gardens gate for 1 over and back. I recommend bringing hydration. Have fun and enjoy the beautiful scenery up top as you catch your breath. 

Big Schloss is another treasure in the George Washington National Forest. Relatively easy at only 4.4 miles and 1,000 vertical feet, it's the sister hike to Tibbet Knob which heads to the south from the same parking location. Tibbet Knob has two short rock scrabbles, but a 10th of the hikers, and just as good views.
