The water is as intrinsic to Skopelos island life as the land, so getting out on a boat is highly recommended.
During summer various boat trips depart daily from the harbour in Skopelos Old Town. Day trips include to the small harbour of nearby Alonnisos, to the marine sanctuary on the far side of Alonnisos and to Skiathos. Dolphins are often sighted on each of these trips.
Small boats can be hired from the harbour and from Panormos beach on the west coast. At greater cost, it may be possible to hire your own larger boat (and skipper) for the day for a trip around the island.
Sea kayaking has become popular around the island coast with kayaks available for hire.
Sofia, the owner of 39 Steps, knows the options and would be happy to advise.
