A fairly difficult hike when you're not trained (which was my case) but not impossible if you take your time and go at your own pace. On the other hand, it's a very beautiful hike! The landscapes are magnificent. There are two parking lots, the Masousa parking lot and another higher up which saves 45 minutes, but the road is very bumpy.
