As pretty at the top as at the bottom, lots of ways to get to the top, accessible for all levels (not technical but lots of elevation gain depending on your starting point) but it's worth it!

Great view! And those on all sides, some areas where it is easier to get your hands on (over 100 meters) but nothing insurmountable! No dangerous areas!
