Great trail with amazing views. I highly recommend bringing 3L of water per person AND a filter of some source for stream water. We ran out but were lucky a friend had a filter. The forest hike is lovely with dense foliage. The switchbacks are when I felt the trail began to get truly tough, but keep going and it will be worth it. The tunnel is on a left slant and you will have to duck as it is short, so be aware of that if you are unable to squat down to walk awkwardly. The cable walk is not terrible but be sure footed. I strongly advise to wear ankle supporting boots as the shale on the switchbacks down can be hard on the body.
