Isla de Benidorm sits just off the skyline of towers, close enough to feel like part of the resort but far enough to change the mood completely. Boat trips run from the harbour in season, giving a quick escape to clearer water, seabirds, and views back to the Levante and Poniente beaches.
There is not much development on the island, which is exactly the point. Bring water, sun protection, and realistic expectations: this is a short sea outing and viewpoint, not a full-day island resort.
