Sesimbra: visit to the Caves

If you’re craving a mix of adventure, natural beauty, and a touch of mystery, the boat tour to the caves near Sesimbra offers just that. This two-hour excursion takes you along the scenic coast of Praia da Mijona, guiding you into an underground world filled with stalactites, stalagmites, and impressive rock formations that have formed over thousands of years. It’s a trip designed for curious travelers who appreciate geology, stunning scenery, and a splash of adrenaline with your sightseeing.

What I really like about this experience is how accessible it makes exploring caves that might otherwise be out of reach for most visitors. The boat guides are knowledgeable, and the strategic lighting inside the caves creates a truly atmospheric atmosphere. Plus, the chance to swim in the crystal-clear waters afterward adds a refreshing ending to your adventure. That said, because the tour involves boat navigation and some time in the open water, it’s worth considering if you have mobility issues or are uncomfortable on small boats.

One thing to keep in mind is the need for flexibility—since the tour depends on weather conditions and group sizes, it’s always good to check availability and organize your schedule accordingly.
