Nea Kameni
Nea Kameni is the youngest land mass in the Aegean, still cooling from its last eruption in 1950. The island at the centre of Santorini's caldera is the geological present tense of the catastrophe that buried Akrotiri 3,600 years ago.
At a glance
Nea Kameni (New Burnt Island) occupies the centre of Santorini's caldera, 2 km from the port of Fira. The island was formed by a series of volcanic eruptions over the past 2,000 years, with the most recent significant activity in 1950. Walking on Nea Kameni is walking on rock that was molten within living memory: the ground is warm underfoot near the crater, and sulphurous gas vents mark where the island is still technically active. The geology is raw — no soil, no vegetation beyond a few pioneering plants in crevices, nothing softened by time.
Key facts

- Height: 127 m above sea level
- Status: Technically active; monitored continuously
- Access: Boat tours from Fira (20 minutes crossing); no private landing
History
The Kameni islands are the youngest surface expression of the Santorini volcanic system. The first recorded eruption from this vent was in 197 BC, which created the island of Palea Kameni (Old Burnt Island). Nea Kameni emerged from the sea in 1707 after a series of eruptions and continued to grow through activity in 1866, 1925–26, 1928, 1939–41, and 1950. Each eruption added lava flows and raised the island's elevation slightly. The 1926 eruption destroyed several villages; the 1950 activity produced the most recent new land.
The island sits directly above the magma chamber that drove the Minoan eruption of c. 1600 BC — the event that buried Akrotiri and reshaped the entire Aegean Bronze Age.
What you see
Visitors land at a small concrete jetty and climb a path to the crater rim over black and rust-coloured lava fields. The surface cracks in places to reveal orange heat below; sulphur crystals — bright yellow — form around the gas vents. The crater itself is 150 metres across, shallow, and emits steam and gas in variable quantities. From the rim, the caldera walls encircling the island in every direction make visible what the Minoan eruption actually did: the entire interior of a giant volcano collapsed into the sea, leaving these vertical cliffs as the outer rim.
The crossing from Fira gives the best view of the caldera scale before landing.
Practical information
- Boat tours from Fira old port (cable car down from town centre): typically combined with Thirassia or hot springs
- Walking shoes essential; the lava surface is sharp and uneven
- No shade on the island; hat and water mandatory in summer
- The island can close when seismic activity is elevated; check locally
- Allow 1–1.5 hours for the crater walk plus boat transfer time
Getting there
Boat tours depart from Fira's old port (Skala Fira), reached by cable car or donkey path from the town above. Multiple operators offer caldera crossings to Nea Kameni, often combined with swimming at the volcanic hot springs of Palea Kameni or a visit to Thirassia island. Journey time: approximately 20 minutes each way.
Nearby
- Palea Kameni — the older volcanic island adjacent, with sulphurous hot springs for swimming
- Fira (2 km) — the caldera-rim capital and departure point for boat tours
- Oia (13 km) — best viewed from the water on the return crossing
