GR20 is a long-distance route located on the island of Corsica (France), in the middle of the Mediterranean. The recommended route takes us from Conca in the south-east of the island to Calenzana in the north-west. The route is perfectly signposted with the marks of the long distance paths, two stripes, one white and the other red. Along the route there are mountain refuges guarded that offer anything necessary but due to the massive influx in the summer months it is necessary to make a reservation. The path, despite being situated on a Mediterranean island, runs through surprising alpine landscapes creating a magical mixture. "Digital Hiking Guide" is the proposal of **HIKEORAMA** as an assistant in long distance routes. It includes in a single application all the necessary information in your routes. Maps, meteorology and information of all the points that you will find along the way. All this presented in the most accessible possible way. It will allow you to position yourself on the route and will help you to take better decisions.
