Santorini Tour of Caldera with Glass bottom Boat

Santorini Tour of Caldera with Glass Bottom Boat: A Practical, Authentic Adventure

If you’re looking to experience Santorini’s famous Caldera from a different perspective, this Caldera boat tour with a glass bottom offers a comprehensive way to see the islands, volcano, and some lesser-known gems—all without breaking the bank. Priced at just over $44 per person, this roughly 5.5-hour excursion is particularly appealing for cruise travelers and families eager to enjoy the island’s volcanic scenery and vibrant waters.

One of the highlights we appreciate is how this tour covers all the key points of Santorini’s volcanic area, including the active volcano, hot springs, and the charming island of Thirassia. The boat’s glass bottom is especially popular among families with kids, providing a fun way to observe the seabed without getting wet. However, a potential consideration is that entry to the volcano itself costs extra, and some may find the overall pace a little tight if they want more time at each stop.

This tour is best suited for travelers who enjoy a mix of sightseeing, light adventure, and scenic cruising—especially those who appreciate natural beauty and want a well-rounded experience of the Caldera with minimal hassle. If your travel style involves quick, picturesque visits with opportunities for swimming and photo ops, this tour could be just right.

Exploring the Itinerary: What to Expect from Start to Finish

Starting Point and Duration

The tour begins promptly at 10:45 am at the Santorini Old Port, with Dakoutros Bros J.V. operating the experience. Expect a group size capped at around 70 travelers, so while it’s not intimate, it’s still manageable. The journey runs for approximately 5 hours 30 minutes, which means you’ll cover quite a lot of ground in a relatively short window.

Visit to Santorini Volcano

The first and most anticipated stop is the active volcano, which is both a highlight and the most physically demanding part of the tour. You’ll climb about 20 minutes to the crater, following your guide—who will likely be a local with good knowledge of the volcanic activity. The volcano is the youngest landform from the big eruption that shaped the island, and standing on its craters gives an immediate sense of the island’s volcanic origins.

The reviews mention that the staff is notably friendly and helpful, with clear instructions on meeting points and times at each stop. Nicholas_K comments that the views from the upper deck are “magnificent”—which is true, especially when you’re close to the volcanic landscape and the ocean.

Hot Springs Experience

Next, the boat heads toward Palaia Kameni, where the hot springs are located. The boat anchors just outside a small bay, and from there, you can lower yourself into the water via a ladder. The best part? It’s free to access the springs, which is a big plus considering many tours charge extra for hot springs visits.

Susanne_R highlights the thrill of jumping straight from the boat into these natural thermal waters, describing it as a “great experience.” The springs are a unique feature of Santorini’s volcanic activity—geothermal heat bubbles up through the water, creating a warm, mineral-rich environment perfect for a quick swim or relax.

Thirassia: A Step Back in Time

The next stop is Thirassia, a less-visited island that offers a glimpse of what Santorini might have looked like 30 years ago. You’re given two hours to explore, whether that means swimming in the crystal-clear waters of Korfos or enjoying a leisurely lunch in one of the traditional taverns.

From the reviews, it’s clear this stop is a hit with travelers who want a taste of authentic island life. The scenery is stunning, and many find the chance to relax in a quiet setting a nice contrast to the busier Santorini. Be aware that you’ll need to plan your own meal or snacks here, as lunch isn’t included.

Underwater Reef and Calm Waters

Following Thirassia, the boat passes over a notable reef, offering spectacular views of the steep and deep waters of the caldera through the glass bottom. This is especially appealing for those who want a peek beneath the surface without diving or snorkeling, adding an educational touch to the tour.

Finally, the cruise returns to the port, with the journey ending where it began. The entire experience is designed to give a rundown of Santorini’s volcanic and island scenery, combined with some fun and relaxation.
