From the port, summer boats run north and south along a stretch of coastline that is essentially inaccessible by road. The cliffs between Puerto de Sóller and Deià fall straight into the sea — no beach access, no walking path close to the water — so the boat is not a tourist luxury but the only practical way to see this section of coast from the right angle. The landscape is remarkable: vertical limestone walls, scrub pine clinging where it can find a foothold, the occasional hidden cove appearing and disappearing as the boat moves along. Many of those coves can be reached only by swimming from the boat or arriving in something small enough to slip inside.
Scheduled ferries in summer connect Puerto de Sóller to the smaller beaches north of the port and south toward Cala Deyà, the rocky cove below Deià village. Sunset runs are popular and deservedly so — the western light on the Tramuntana from the water is one of the better views available in this part of Mallorca. Departure times vary by season and year; check at the port on arrival. Out of summer the service reduces substantially and some routes stop entirely, so this is a genuinely seasonal pleasure.
