Boat Trip Benidorm to Alicante

Benidorm Island is the only inhabited island along the Costa Blanca, yet no permanent population lives there—only day visitors who arrive by ferry from the mainland. The island's marine reserve, established in 1952, protects grouper, octopus, and damselfish populations that cluster around the submerged rock formations ringing its base. Every ferry crossing includes an Aquascope session: passengers descend into a glass-bottomed observation chamber built into the hull, where they watch the reserve's marine life pass beneath the boat in real time. The crossing itself takes fifteen minutes from the Passeig de Colom dock to the island's single landing jetty on its eastern shore. Ferries operate on a continuous loop throughout the day, eliminating the need to book a specific return time—visitors simply queue for the next available boat when ready to leave. The Aquascope segment occurs midway through the outbound crossing, with the boat pausing for five to seven minutes above a marked section of the reserve where visibility typically reaches eight to twelve meters. The island itself spans 70,000 square meters, with a footpath network connecting the jetty to the island's three restaurants, a small pebble beach on the northern side, and a trail that climbs to the summit viewpoint at 73 meters elevation. Most visitors spend two to three hours ashore, enough time to complete the summit loop and return via the coastal path. The marine environment around the island is warmest between June and September, when water temperatures reach 24–26°C and Aquascope visibility peaks. Outside summer months, surface conditions remain calm but underwater visibility can drop to five meters during periods of wave action. The ferry service operates year-round with no advance reservation required for individual tickets. Departures run every thirty to forty-five minutes depending on passenger volume, with the highest frequency between 10:00 and 15:00. The island boat excursion from Benidorm remains one of the few Mediterranean island crossings that includes a submarine viewing component as standard, rather than as a separate tour add-on.
