If there's a route that perfectly summarizes the mountainous landscapes of Madeira island like no other, it's definitely the one that connects the peaks and Ruivo Arieiro in Sendera known as PR.1. Like almost all the routes on the island, it's well-marked and mapped out, while presenting the unevenness (which is a real leg-buster) of more than 800 vertical meters). The length of the return path is 7 hours and it's not an easy task by any means. Many people start the trail early in the morning (around 8 a.m.) and the trip back doesn't happen until later in the afternoon. Now, the effort is well worth it, even if you only do a part of the trail.
