Santorini owes its dramatic beauty to a fiery past—one shaped by one of the most powerful volcanic eruptions in recorded history. Around 1600 BCE, the volcanic explosion that created the island’s iconic caldera also changed the course of the Aegean world, giving rise to myths like Atlantis and leaving behind a geological wonder that still bubbles with geothermal life today.
At the heart of this natural marvel lies the Santorini volcano, a sleeping giant surrounded by surreal landscapes, steaming craters, and therapeutic hot springs. And while the island is famous for its whitewashed cliffside villages and stunning sunsets, no visit to Santorini is complete without exploring its volcanic soul.
Here are 5 unforgettable volcano tours that bring you face-to-face with the island’s explosive origins and offer a unique adventure unlike anything else in the Cyclades.
1. Hiking the Active Volcano of Nea Kameni
Nea Kameni, the larger of the two volcanic islets in the middle of Santorini’s caldera, is a stark contrast to the romantic villages of Oia and Fira. Here, the landscape is wild and primordial—jet-black lava fields, sulfur vents, and jagged rocks that feel like another planet.
A hike to the summit of Nea Kameni is one of the most iconic and accessible volcano experiences. Most tours depart from the Old Port of Fira and include a scenic boat ride across the caldera to the islet. Once there, a guided walk leads you along a dusty trail past fumaroles and craters until you reach the top, where the view is as breathtaking as the climb.
Your guide will explain the geology of the volcano, its last eruptions (the most recent being in the 1950s), and how the island continues to rise and shift due to tectonic activity.
What makes it unforgettable:
Standing at the edge of an active volcanic crater, surrounded by the echo of distant eruptions, you’ll feel the immense power that shaped Santorini.
Duration: 2–3 hours
Best for: Hikers, geology enthusiasts, photographers
2. Caldera Cruise with Hot Springs Swim
Combine exploration with relaxation on a caldera cruise that includes a volcano visit and a dip in the hot springs of Palea Kameni. These tours are perfect for travelers who want to enjoy both the geological and indulgent aspects of the island.
After hiking Nea Kameni, the boat sails to nearby Palea Kameni, where you’ll jump into the warm, sulfur-rich waters said to have healing properties. The contrast between the cool sea and the hot springs creates a unique sensory experience.
Many caldera cruises also include stops at Red Beach or White Beach, and some offer onboard BBQ meals, drinks, and snorkeling equipment.
What makes it unforgettable:
Floating in thermal waters in the middle of an ancient caldera as steam rises around you—pure volcanic bliss.
Duration: Half-day (4–5 hours)
Best for: Couples, families, wellness seekers
3. Sunset Volcano Cruise with Dinner on Board
For a more romantic take on Santorini’s volcanic landscape, consider a sunset cruise that combines natural beauty with gourmet dining. These luxurious boat tours set sail in the afternoon, giving you enough time to hike the volcano and soak in the hot springs before anchoring beneath Oia for sunset.
As the sky shifts through shades of gold, pink, and crimson, you’ll dine on freshly prepared Greek cuisine and sip Santorini wine on deck. Some tours are on sleek catamarans, while others use traditional wooden sailboats for a more classic aesthetic.
This is a favorite for honeymooners or those celebrating a special occasion—and watching the sun sink into the caldera from a boat is one of the most iconic experiences on the island.
What makes it unforgettable:
The volcano, the sea, the sunset, and a candlelit dinner—luxury and nature in perfect harmony.
Duration: 5–6 hours
Best for: Romantic travelers, luxury seekers, photographers
4. Private Volcano & Caldera Sailing Tour
If you want to explore Santorini’s volcanic heart at your own pace, a private sailing tour is the ultimate way to do it. These customizable experiences offer exclusivity, flexibility, and high-end service—from private guides and chefs to curated routes and snorkeling stops.
You can choose to focus on the volcano and hot springs, or add detours to Thirassia Island, remote beaches, and hidden caves. Many charters depart from Vlychada Marina or Ammoudi Bay, and your captain will tailor the itinerary to your interests, whether that means a volcano hike at dawn or a moonlit swim near Palea Kameni.
Expect spacious decks, luxury amenities, and the feeling that you’ve got the entire Aegean to yourself.
What makes it unforgettable:
It’s your volcano, your boat, and your schedule. Pure freedom with a touch of opulence.
Duration: 4–8 hours
Best for: Families, VIPs, special celebrations
5. Volcano and Thirassia Island Combo Tour
For travelers who want to go beyond the volcano, this tour includes a visit to Thirassia, the quiet sister island of Santorini, located across the caldera. Once part of the same landmass before the great eruption, Thirassia remains a window into what Santorini was like before tourism transformed it.
After hiking Nea Kameni and enjoying the hot springs, the boat heads to Thirassia, where time seems to stand still. You can explore the sleepy port of Korfos, hike to the hilltop village of Manolas, or simply enjoy a traditional meal at a seaside taverna.
The juxtaposition of the raw, volcanic landscape with the charming simplicity of Thirassia gives this tour a cultural depth that pure volcano tours lack.
What makes it unforgettable:
Volcano meets village—a journey through Santorini’s geological and human past in one day.
Duration: Full-day (6–7 hours)
Best for: Culture lovers, explorers, slow travelers
