Caldera Private Cruise & Volcano Hike

If you’ve ever dreamed of exploring Santorini’s breathtaking scenery without the chaos of crowded boats and tour groups, the Caldera Private Cruise & Volcano Hike might just be the perfect choice. This 3-hour adventure, offered by Spiridakos Sailing Cruises, combines the luxury of a private motorboat with the thrill of hiking an active volcano and swimming in thermal springs — all in a relaxed, intimate setting.

Exploring Santorini’s Caldera on a Private Motorboat

Unlike crowded group cruises, this private outing ensures you have plenty of space to take in the spectacular caldera scenery, with the comfort of your own crewed motorboat. The boat’s spaciousness means you won’t be jostling for position or fighting over space, a common complaint with larger tours.

From the moment you step aboard, the crew’s attentiveness is evident. Reviewers mention how crew members go out of their way to help find parking, or patiently wait if you’re running late. One guest noted how a crew member personally came to find them when parking was tricky—these small touches make a difference when you’re trying to relax and enjoy the day.

The boat is equipped with restroom facilities, water, sodas, and snorkel gear, which makes staying comfortable and prepared easy. As you cruise along, you’ll have ample opportunities to snap photos of the caldera’s iconic cliffs, volcanic islands, and the colorful towns perched high above.

The Volcano Hike: An Active Adventure with Stunning Rewards

One of the tour’s main highlights is the volcano hike. Led by knowledgeable guides, this hike offers a chance to stretch your legs and get up close to the active volcanic crater. Reviewers rave about the guides’ expertise—one noted that their guide was particularly helpful and made the hike informative and safe.

The hike typically takes about 25 minutes to reach the crater, and you’ll get the chance to stand on the edge of an active volcano. While the official admission fee is not included, the experience of gazing into the volcanic vents and feeling the heat beneath your feet feels genuinely special. Several guests also appreciated the flexibility: one reviewer mentioned having extra time to enjoy the views and take photos, which underscores how personalized this tour can be.

For those who prefer snorkeling, the volcanic coast provides an intriguing backdrop for underwater exploration. Snorkel gear is supplied, and reviewers mention snorkeling around volcanic rocks and caves, seeing the deep blue waters and vibrant marine life.

Palea Kameni: Thermal Springs & Hot Springs Swim

Next stop? Palea Kameni, the small island just off the volcano, famous for its thermal springs. The hot springs, heated by volcanic activity, offer a natural spa experience. Reviewers describe swimming here as a uniquely relaxing activity, with some noting the water’s warmth was a delightful contrast to the cool sea.

The stop lasts around 30 minutes, giving enough time to dip in, relax, or simply enjoy the views. It’s a popular moment for many, with guests noting the experience’s authenticity—no crowded thermal springs here, just a peaceful swim with your private group.

Discovering Nisís Agíos Nikólaos

The final stop is the hidden gem of Santorini, the Agios Nikolaos Islet. With its deep blue waters and secluded atmosphere, this spot offers a perfect opportunity for a quick dip or snorkeling session. One review highlighted how they enjoyed diving into these pristine waters, describing it as an “amazing way to end the day.”

This part of the tour is flexible—if your group prefers more time in the water or exploring the nearby caves, your guide can accommodate. The short but sweet stop ensures you finish the trip on a high note with plenty of time to relax and reflect on the day.
