From the cliffs of Lloret de Mar in Girona, Catalonia, the Camí de Ronda winds along the Costa Brava, a coastline true to its name: wild, rugged and full of surprises. This historic route passes hidden coves, rocky outcrops battered by the Mediterranean and pine forests that reach almost to the sea. It was originally established so that customs officers could patrol the coastline and help prevent smuggling. Today, it is considered one of the most spectacular coastal walks in Spain.
