Thirassia was formed by a colossal volcanic eruption that destroyed the larger island of Strogili — present-day Santorini, Asporinsi and Thirassia.

The sleepy volcanic island is just a quick jaunt by boat from the famous honeymoon destination of Santorini.

Thirassia is just as romantic as the famous island with just 300 residents, iconic Grecian architecture and steep winding hills plummeting to vivid blue waters.

While Santorini may feel like heaven, you'll find the region is full of unbelievable islands and undiscovered coves on a Thirassia day trip.

What will you see and do in Thirassia?

Nea Kameni

The first reports that suggest an eruption of Nea Kameni are from the first century. The volcano may be dormant now, but over the last 300 years it has been especially active, and the last recorded blast happened in 1950.

The island is uninhabited, and the only people that step foot upon it are the tourists that pass through on their way to Thirassia. While the land is barren in appearance, visitors can complete a hike to the 130-meter-high crater.

Once there, you can wander around the rim to envisage what it may have looked like when cataclysmic eruptions were occurring. There is a small volcanic crater that is still active on the island and visible to tourists. As you hike to the top, you'll see smoke and smell volcanic sulfur, all of which adds to the excitement.

Palea Kameni

Palea Kameni is another island inside the caldera and was founded by the Roman scientist Cassius Dio. In the present day, the island has just one inhabitant and a flock of goats.

Tourists don't stop at the small island for the farmyard animals though — visitors are drawn in from neighboring Santorini by the Palea Kameni hot springs.

There are several streams of thermal water on the island that boat-trippers can swim in on their day trip towards Thirassia. The water is green but healthy and pleasant to plunge into, and the temperature increases the later in the day that you visit.

Thirassia

If you want to get an insight into what Santorini was like before it exploded in popularity, Therassia is the place to do so. From its tiny port to its scattered villages and towering hills that provide panoramic views of its sister island Santorini, Therassia maintains its traditional charm.

While on the island, you can climb the 270 steps to the village of Manolas or sink your toes into the volcanic black sand beaches.

Alternatively, you can revel in the natural scenery with a heart-thumping hike and visit the abandoned village of Agrilia. 1,000 residents used to call Therassia home but after the last eruption in 1950, many locals fled the island and never returned.

If you want to extend your day tour to Thirassia, consider renting one of the few rooms available. You'll feel the island breath a sigh of relief as the last tourist boat leaves while you explore the island that's frozen in time alone.

Thirassia day trips give you plenty of opportunities to experience the allure of the island if you choose not to stay overnight.

When is the best time to visit Thirassia?

Thirassia experiences a warm and dry climate between May and October with highs of 26 degrees Celsius during July and August.

While only 1% of Santorini's visitors make the short jaunt to Thirassia, the island can still become busy in the peak of the summer.

For that reason, you should consider visiting in May, June or September when temperatures are balmy and boatloads of tourists are limited.

Travel tips

Have cash with you if your Thirassia excursion includes a visit to the Nea Kameni volcano. It costs €2 to access the natural wonder.
It's a steep hike to the crater of Nea Kameni. While you're sure to need flip-flops on your day trip, pack comfortable walking shoes as well.
Sunset is the perfect time of day to experience sailing on the southern Aegean sea. If it fits into your itinerary, you should arrange an afternoon tour to Thirassia.
The hot springs of Palea Kameni can become very warm in the afternoon. Dip a toe in before you slide your whole body into the water.
