Discover Santorini from Rethymno on an 11.5-hour day trip featuring island exploration, guided towns, and optional boat tours, all from a high-speed cruise.

Travelers often dream of experiencing Santorini’s iconic white-washed buildings and breathtaking views—but fitting it into a one-day adventure sounds ambitious.

Whether you love scenic boat rides or wandering charming villages, this trip packs plenty into just over half a day.
What we really appreciate about this experience is the thoughtfully balanced itinerary. You get to see the highlights of Oia and Fira with a knowledgeable guide, plus the flexibility to explore at your own pace. Plus, the optional boat tour to the volcano and hot springs is a hit with many travelers who want a bit of added adventure.
Of course, the main consideration is the duration—11.5 hours can be long, especially if you’re not a fan of tight schedules or if you’re prone to seasickness.

The day kicks off early with pickup from a list of 27 convenient locations around Rethymno. This logistical detail is a real plus—no need to worry about complicated transportation. Once everyone’s aboard, you’ll hop onto a high-speed catamaran cruise, which is surprisingly comfortable and quick, giving you a scenic ride across the sea with plenty of opportunities to soak in the views.
Many reviews mention that the boat ride is both smooth and relaxing, with some travelers noting the chance to catch a quick nap or snap photos of the coastline. The cruise itself is a highlight, especially if you’re someone who enjoys the sea and wants to avoid the hassle of driving or ferries.

The first stop on land is Oia, famed for its picture-perfect streets, cave buildings, and stunning sunsets. Here, the guide introduces you to the town’s unique architecture—rock-hewn cave houses, grand captains’ homes, and charming boutiques. Several travelers noted that Oia’s beauty is mesmerizing and worth the free time to wander.
One reviewer mentioned, “Oia is everything you imagine—narrow streets, whitewashed walls, and that famous blue dome. It’s a photographer’s paradise.” The free time allows you to explore independently, pick up souvenirs, or simply sit with a coffee and watch the world go by.
Next, the group moves to Fira, the island’s lively capital. The tour guide meets you in front of the Orthodox Cathedral Panagia, giving you an overview of what to see and do. Here, you can choose to take a boat tour to the volcano or relax in the town.
Many travelers appreciate the flexibility. Some mentioned that the guided walk in Fira is informative, offering context about the town’s history and sights. Others took the chance to shop, grab a snack, or sit in a café overlooking the caldera.
One of the most talked-about extras is the boat trip to the Palea Kameni volcano and the hot springs. The traditional wooden boats ferry visitors to the volcanic island, offering a close-up view of the active crater. Many reviews highlight that seeing the volcano up close is a unique feature of this tour.
If you opt for the hot springs, be prepared to pay extra on the boat—some travelers found it worth the splash. The springs are said to have therapeutic properties, and a swim here offers a refreshing break. However, if you’re not into optional add-ons, you can skip this part and spend more time in Fira.
