A low wooden bow parts the blue; the kaiki rocks forward and the caldera cliffs rise like weathered pages. On a five-hour traditional cruise from Vlychada, the wind pushes the boat toward Red Beach’s rust-streaked cliffs, past the white outcrop of White Beach, around the volcanic islets and into the sheltered cove of Ammoudi Bay at Oia.

A low wooden bow parts the blue; the kaiki rocks forward and the caldera cliffs rise like weathered pages. On a five-hour traditional cruise from Vlychada, the wind pushes the boat toward Red Beach’s rust-streaked cliffs, past the white outcrop of White Beach, around the volcanic islets and into the sheltered cove of Ammoudi Bay at Oia.
Santorini’s caldera is a collapsed volcanic crater formed by the massive Minoan eruption roughly 3,600 years ago; the islands you circle are layers of lava, pumice and ash visible as stark bands on the cliffs. Local culture here combines seafaring and farming—fishermen still use wooden kaiki and island kitchens favor simple, hearty dishes; lunch aboard typically features chicken, Greek salad, stuffed vine leaves and local white wine.
The trip includes multiple swim stops — Red Beach for dramatic color, the volcanic hot-spot waters around Nea Kameni, and Thirassia’s quiet shoreline for snorkeling and a dockside swim. The turquoise and black rock push the current into small eddies that dare you to dive; visibility for snorkeling is usually good in calm conditions.
Practical guide: bring reef-safe sunscreen, water shoes for rocky landings, and a swimsuit under your clothes to speed boarding. Pickup is by A/C minibus from many hotels; reconfirm the time 24 hours ahead. The cruise is family friendly and rated physically easy, but basic swimming skills are required for snorkel stops. Mornings are cooler and crowds thinner; late spring through early fall offers the warmest sea conditions.
Expect traditional hospitality, uncomplicated Greek fare, and a day that balances geological spectacle with easy, memorable sea time.
