Puig Campana is the second highest mountain in the province of Alicante in Spain. The route starts at "Font del Moli" and if you forgot water, don't worry! You can fill your bottle at the fountain with spring water before you go up (take at least a liter and a half, you will need it). You follow the PR-cv 289 path until "Coll del Pouet" and then you start the most technical part of the route and follow the sign "Puig Campana 1408m". It is quite dangerous and markings on rocks are very faded so you have to pay attention. What you get in return is a fantastic view over Benidorm and if the sky is very clear you can even see the island of Ibiza. The descent is difficult because of the loose rocks so focus is very important. When you arrive back at "Coll del Pouet" you continue the loop and still follow PR-cv 289. The heat makes the route extra difficult but it is completely worth it.
