Santorini Boat Tours

Hike the volcanic trails of Nea Kameni | Hot springs, lava trails, and epic views

Located in the heart of the Santorini caldera like something out of another planet, Nea Kameni is a rugged, uninhabited volcanic island. This small isle was born from eruptions over the past two millennia, with the most recent one in 1950. You'll find it smack in the center of the flooded crater, ringed by Santorini’s cliff-top villages. Hike up its ashen trails, and you're walking on layers of lava and history. Plus, the views from the top? They’re a whole new way to see Santorini.

Reasons you’ll love visiting Nea Kameni

You’ll be exploring the island’s unique geology

This isn’t just any old island, it’s actually one of the youngest volcanic landforms in the Eastern Mediterranean, still steaming from its last eruption in 1950. You’ll hike across jet-black lava fields, pass sulfur vents, and see craters that feel strangely lunar.

The views from caldera are amazing

Turn around mid-hike and you’ll see why this place draws photographers, painters, and daydreamers alike. From Nea Kameni’s highest point, the sheer cliffs of Santorini curve around the blue caldera like a natural amphitheater.

You don’t need hiking boots, just a sense of curiosity

It’s a volcano hike, sure, but don’t let that scare you off. The paths are manageable, the pace is your own, and the terrain while rugged isn’t technically challenging. Throw on sturdy shoes, carry some water, and you’re all set.

It’s part of the full Santorini cruise experience

Nea Kameni is often just one part of the full-day tour. Most tours also stop at Palea Kameni, where you can swim in warm, mineral-rich waters just off the boat, and Thirassia, a quieter cousin of Santorini with postcard-perfect villages.

History of Nea Kameni

Nea Kameni, as you see it today, is surprisingly young in geological terms. It started forming less than 500 years ago, born from a series of underwater volcanic eruptions inside the flooded Santorini caldera. What you’ll be standing on is a pile-up of lava domes and ash layers from eruptions that happened between 1570 and 1950. The most recent eruption left behind steaming vents and gave it that cracked and scorched look.

It might feel ancient, but Nea Kameni didn’t even exist during the Minoan eruption that buried Akrotiri around 1600 BCE. In fact, it grew gradually, over centuries, with each eruption adding a bit more land. Greece declared it a protected scientific site in the 20th century, and now it’s closely monitored by volcanologists.

Is the Nea Kameni volcano active?

Yes, Nea Kameni is technically an active volcano but there’s no need to panic. In geological terms, “active” just means it’s erupted in the last 10,000 years and could erupt again, which is true for many volcanoes around the world, like Mount Etna in Italy. Nea Kameni is closely monitored by experts, declared a protected scientific site, and completely safe to visit. If there were ever signs of unusual activity, authorities would alert the public well in advance.

Hiking the volcano: What to expect

A trail across ash and lava

The trail to Nea Kameni’s summit is around 1.5 to 2 km round-trip. It’s a moderately easy hike, but the terrain is dry, dusty, and uneven in parts, with loose volcanic gravel underfoot. Trails are clearly marked, and some cruises do offer local guides to help you navigate.

Crater views and sulfur vents

As you approach the top, you’ll notice wisps of steam rising from small sulfur vents. The craters and rock formations shift in colour from black to rust-red, making for striking photos. Safety ropes mark off active vent areas, so just stay behind them.

Panoramas of the Caldera

At the summit, you're treated to sweeping 360° views across the flooded caldera. You’ll see the whitewashed villages of Santorini perched high on the rim, and the island of Thirassia just across the water.

How to plan your visit

  • It’s accessible only by boat.
  • Opt for a cruise tour that includes Nea Kameni with hot springs and nearby islands. You get the full experience in one go.
  • Morning hikes are ideal. Cooler temperatures and softer light make early hours the most comfortable for walking.
  • Midday can get hot especially in peak summer (July–August).
  • Spring and autumn are sweet spots. April to early June and September to October offer pleasant weather and fewer crowds.
  • You can also opt for Sunset hikes if they are available. 
  • The trail is going to be dry, uneven, and covered in loose volcanic gravel. So make sure you wear closed-toe, non-slip walking shoes. 
  • Bring plenty of water. There’s no shade or facilities on the island, and it gets hot fast.
  • Pack reef-safe sunscreen and a light hat.
  • You’ll want your hands free while climbing or taking photos. Carry a lightweight backpack for your essentials.
