Amazing hike! Best advice I can give is to wear shoes with ankle support. I'm pretty fit, but it's super rocky terrain and rolled my ankle on this trail. I wasn't wearing proper hiking shoes (just good pair of low-top running shoes). I would say this hike is more on the strenuous side just because of the sharp inclines and rockiness of the trail.
As you walk, you'll find little air vents with cool air coming out, take advantage of them!
You'll be tired when you get to the top, but make sure you go to Sprouting Rock! It's really close and beautiful.
