The most beautiful and perhaps the most famous hiking trail on the island, it is a path along the caldera where you will be walking among red and black rocks with a great view of the deep blue. This is the old trail that connected the capital with the northern side, Ia, before the construction of the road. The route is not relatively difficult; however, closed shoes are required since the ground is unstable in some places. Also avoid the mid-day hours since shaded spots are scarce. Do not forget to make your offer to the god Hermes, by creating your own tower with stones! A path, with the scent of thyme to accompany you. You will find informative wooden boards along the route. (approx. 12 kilometers)
