View of Santorini island from Thirassia

A boat trip to Thirasia, the Santorini of 50 years ago

Visiting the island of Thirasia, on the other side of the caldera, is like travelling to Santorini when it was still a rough diamond awaiting discovery.

Imagine being able to travel to Santorini as it was before the cosmopolitan vibe. To when the landscape was all about raw volcanic beauty rather than whitewashed glitz and glamour. Well, on Thirasia - one of the islands you can see from Santorini as you look across the caldera – you don’t have to imagine. 

It was originally part of the large island of Strongilis, which collapsed during the Minoan eruption to form a cluster of islands (that includes Santorini and Palea and Nea Kameni) and the iconic caldera that unites them. As such, it shares the same volcanic geology as Santorini, and was similarly inhabited in the past, but it experienced none of its explosive growth as a tourist destination.

So to take a day trip there is to be given a rare glimpse into the past. To a version of Santorini when it was a rough diamond, with just over 300 inhabitants, and a slow-paced, unchanging way of life that will, most likely, still be the same 50 years from now.

Korfos port

One of the two ports on the island, where you can enjoy seafood in traditional tavernas and swim, with views of the characteristically volcanic landscape and Santorini.


The main town of Thirasia is built just above Korfos, at the island’s highest point. It’s got the same dramatic clifftop feel as Santorini, but with views from the other side of the caldera. You’ll find traditional Cycladic houses, narrow streets and small village shops. It’s worth carrying on the path south of Manolas. You’ll get to the church of Prophet Elias, probably the best viewpoint.


Built in a ravine, from where it got its name (River), Potamos is about 1km inland from Manolas. It has beautiful houses with courtyards and two churches in the centre, Agios Dimitrios and the colourful Panagia Yatrissa.

Agia Eirini (Riva harbour) 

The main port, at the northern end of Thirasia, this will be your first stop if you arrive by ferry. You can enjoy a seafood meal here in a traditional tavernas and have a dip at a beach with striking black pebbles. 


The oldest settlement on Thirasia is no longer inhabited, which makes it especially interesting to explore, especially the remains of the houses built right into the rock. To get here, you’ll most likely need to complete a 2km walk from Manolas. You’ll be rewarded with a raw volcanic landscape along the way.
