The hike up Mount Teneriffe is not an easy one - in my opinion, it's the most strenuous summit one can find for 4 points. There are 2 main routes to the summit; the new trail / road walk, which is about 13+ miles round trip, or, the more direct route; Kamikaze Falls then up Serendepity Ridge. I've done both routes multiple times - I prefer the much shorter Kamikaze Falls / Serendepity Ridge as it's only about 7.5 miles round trip. As this route is about half the length of the new trail / road walk, it's obviously steeper - really steep! A few short easy rock scramble sections. With either route, the net gain from the trailhead to the summit is 4100 feet. The hike through the forest is beautiful, and the trail, better described as a boot path, is fairly obvious - just stay on the ridge.
