From the port, head south towards Les Rotes. The houses located on the right are noteworthy, situated in an area where two old fishing neighbourhoods are located. Further on, along the left-hand sidewalk, you can see the sailing club called Real Club Náutico.
Continue along the outer sidewalk that diverts you away from the Les Rotes road and takes you along the coast until you reach a roundabout with a monument: the so-called Montgó Monument, made by the sculptor Castejón and representing the great mountain. From this point onwards, continue along the promenade that you can see, that runs along the shore of the Marineta Cassiana beach, the only sandy beach in Les Rotes. This walk extends along the entire beach.
If you continue the walk, you get to the rocky coves of Les Rotes. The great beauty of this rugged landscape is truly noteworthy, with the green and blue colours of the sea standing out, together with the transparency of the water and the nooks created by the meandering coast. As soon as the rocky coves start, you are in the Cabo de Sant Antoni Marine Reserve, which means that the entire area (including the coves and the cape up to its easternmost point) is environmentally protected.
In the last section of the walk, if you raise your eyes to the right (away from the sea) you can see a small tower on a hill: Torre Gerro, a defensive watchtower from the 16th century.
Long before getting to the end, the cliffs of Cap Sant Antoni can be seen in the distance, with their huge drop of over 160 metres, although you have to go to the end of the Les Rotes road to see the most impressive views. After reaching the end of Les Rotes, backtrack all the way, walking again along the paths by the sea that lead you back to Dénia, although you can also take a local bus back to the starting point.
