Beautiful views, challenging, nice exercise.
The heat and altitude made it a little difficult. Be prepared with lots of water, gatorade, and a snack. Expect it to take 4.5 hours from car park to tram.
At the recommendation of friends, we rode the tram down. The base of the tram is about 3 miles from the car park entrance to the trail. If interested in hiking this trail, google La Luz.
