Sheltered Sesimbra rock arch with easy boat access
A Sesimbra operator is the practical way to time the boat and choose a calm day.
Pedra do Leao (Lion's Rock) is a sheltered Sesimbra boat dive built around a shallow rock arch, sand patches, and easy passage through a compact rock formation. It suits relaxed scuba, snorkeling, and newer certified divers, with schooling fish under the arch and a simple day-plan when the sea is calm, making it a good low-stress choice when the local water stays settled.
