Glide silently from Denia aboard an electric sailboat to search for dolphins and whales in the Cabo de San Antonio marine reserve. Small groups, a marine guide and a hydrophone make this a hands-on conservation-focused sea experience.
More ways to explore the area's outdoor wonders
Dawn light spreads across Denia’s harbor as El Som Mar slips quietly from the quay, its electric motor letting the sea sound lead the way. Guests stand along the deck, coffee in hand, eyes on the horizon where the pale blue of the Mediterranean meets the darker line of Cabo de San Antonio. The boat’s silence makes the first clicks and whistles—picked up by a hydrophone—feel intimate and immediate.
