Just beside Port de Sant Miquel you can find this tiny cove, to get here you´ve got to park in Port de Sant Miquel and walk to the beach for the left-hand side. After the last restaurant on your left you´ll see a tiny path with a rustic sign to the left. This path will take you to Caló des Moltons after a 5 minute walk.
It´s not a hard track, it is not solid neither, but it is not difficult to get here if you´re kind of fit. It is worth the walk if you like calm. There´s a small chiringuito here so you don´t need to take a cooler with you.
Recommended : a pair of sneakers to get here.
