A low-slung wooden boat eases away from Fira’s old port, the caldera walls rising like cliffs of broken light around you. Salt air pulls at your jacket while the captain angles the bow toward the dark cone of Nea Kameni; the island’s fumaroles faintly steam, daring you to step closer and feel the raw geology beneath your soles.
moderate.
5–6 hours.
Suitable for travelers who can walk 20 minutes on uneven ground and swim short distances; not strenuous but requires mobility.
The path to the active crater takes about 15–25 minutes each way on loose volcanic rock; allow time to explore at the rim.
Yes—there’s ladder access to the water for swimmers, but non-swimmers can stay on board during the swim at Palaia Kameni; basic mobility is still needed for boarding.
The waters near Palaia Kameni are warmed by geothermal activity (roughly 30–35°C mixed with seawater); swimming and mud baths are common but avoid if you have open wounds or certain health conditions.
The operator indicates it’s family-friendly and offers infant seats; however, keeping children supervised during ladder boarding and the volcano walk is important.
The caldera formed during a massive Minoan-era eruption; Nea and Palaia Kameni are relatively young volcanic islands created by later eruptions and ongoing geothermal activity.
Stick to marked paths on Nea Kameni and avoid removing rock or biological material; use reef-safe sunscreen to limit chemical impact on local marine ecosystems.
