Pick-up from the hotels. The volcanic island of Santorini lies north of Crete. And this daytrip by fast catamaran is a great chance to take a close-up look at it. Curved around a colossal, sea-filled caldera that was formed by a massive volcanic eruption 3,500 years ago, it's all black cliffs, whitewashed villages and blue-domed churches. It's picture-postcard Greece. Once you're on dry land, you'll take off on a scenic tour, exploring many of the island's attractions and learning about its history. Explore a calderaedge town, where whitewashed houses, cobbled streets and tavernas cascade down the cliff-face in steep terraces. You'll then have some free time in both Oia and the island's capital - Fira, where you will have a possibility to take a cruise to the volcano. Spend an hour or so snapping up treats in the quaint shops and boutiques. Or visit some of the best lookouts to take photos – the views over the caldera are great. It's made for selfies. Return to the hotels.
