I have walked this Trail at least a dozen times in my life from the late '80s on. The Beatles killing the area has really ravaged the trees but the views are still spectacular around Hancock up to the tunnel entry point. This is an easy hike for just about anyone. If you choose to make it more difficult you can take Altman Trail over the top and check out the West Portal which has more of the historical structures and small museum. It's a bit of a hike for sure but worth it if you're in shape.
