Santorini Volcano Cruise: Nea Kameni Hike and Hot Springs Swim

Your tour begins at Fira Old Port (Santo Star Office)

Check in by 10:30 am at the Santo Star Office, then board in Santorini’s Old Harbor. Meet your guide, grab a spot on deck, and cruise into the caldera as the cliffs rise ahead.

Cruise the caldera toward the volcanic islets

Glide across deep-blue water with Santorini’s rim villages stacked above the sea. Your guide explains how the caldera formed, while you snap photos of lava-rock shores and whitewashed towns from the boat.

Hike Nea Kameni’s volcanic paths

Step onto Nea Kameni and follow your guide along black lava trails toward the crater. Hear how eruptions shaped the island, then pause for sweeping caldera views before you head back down to the boat.

Swim at the hot springs of Palea Kameni

Next, anchor near Palea Kameni and slip into sulfur-rich warm water by the hot springs. Float with the foam pool noodles, or stay on deck and watch the steamy shoreline while the boat waits nearby.

Your tour ends at Fira Old Port

Cruise back across the caldera with the volcanic islets fading behind you. Your guide wraps up the experience as you return to Fira Old Port, ready to keep exploring or settle in for a seaside lunch.
