Thirasia, also known as Therasia or Thirassia, is a small island located near Santorini in Greece. Although it is often overshadowed by its more famous neighbor, Santorini, Thirasia has its own charm to offer. Here are some notable things to see and do on Thirasia:

Traditional Villages

Thirassia

Thirasia is known for its picturesque villages and traditional Cycladic architecture. Manolas, the island’s capital, is particularly charming, perched on a cliff with stunning views of the Aegean Sea. Explore the narrow alleyways and whitewashed houses while enjoying the peaceful atmosphere. The traditional settlement of Potamos above Riva features many blue-domed churches at its center, along with cave-style houses built right into the rock.

The abandoned village of Agrillia is the oldest and was once the largest village on Thirasia. Although it’s uninhabited now, visitors can see the remains of cave houses and cellars that have been overtaken by nature, providing a hauntingly beautiful scene. At its entrance is one of the Aegean’s most elaborately decorated churches. Dedicated to the Virgin Mary, the Church of the Presentation of the Virgin Mary was built in 1887.

Hiking & Scenic Walks

Thirassia Countryside

Thirasia’s rugged landscapes and scenic paths make it a paradise for hikers and nature enthusiasts. You’ll find a breathtaking view from nearly every angle. There is only one road that connects Thirasia’s five charming villages, with most locals getting around on mules are mopeds, making it ideal for exploring on foot. Simply select a path and wind through the hauntingly beautiful volcanic landscapes. You’ll find plenty of spots to rest while marveling at the beauty of the endless blue of the sparkling Aegean Sea.

You might take a trek up to the Thirasia Caldera, a volcanic crater, to witness awe-inspiring views of Santorini and the surrounding islands. The island’s main settlement, Manolas (or Chora), was built right at the caldera’s edge and overlooks Imerovigli. No matter where you are, expect spectacular views that will immerse you in Thirasia’s striking natural beauty.

Beaches

Thirassia Beach

Thirasia boasts several beautiful and secluded beaches, providing a tranquil oasis with clear sapphire waters for swimming. Korfos Beach is a popular choice, accessed by a path from the village of Manolas. Made up of black pebbles and pumice stones edged by a translucent turquoise sea, it offers stunning views of Santorini’s caldera and dramatic cliffs. Bring your own supplies, including an umbrella, water, and snacks.

Riva Beach, right at the main harbor in Riva, has a mix of dark sands and striking black pebbles framed by crystal-clear blue waters. Several charming tavernas are nearby in the settlement. Saint Irene (Agia Irini) is an easy stroll away and is one of the island’s best volcanic beaches. It offers caldera views and the chance to swim with few others around, even during the peak of the tourist season.

Dormition Monastery

Dormiton Monastery

Also known as the Monastery of Kera, the Dormition Monastery was built in 1851 on the southern side of Thirassia on Cape Tripiti. Offering a unique mix of archaeological and religious interest, its most notable feature is a golden Russian temple with five domes, a belfry with an unusual shape, and an interior covered with frescoes. It also offers awe-inspiring views of Santorini and its caldera while a prehistoric settlement nearby features preserved walls, stone tools, and ceramics.

Tavernas & Local Cuisine

Greek Taverna

Thirasia is known for its traditional tavernas that serve authentic Greek cuisine. Indulge in local specialties such as fava, a puree made from split peas, or tomatokeftedes, which are delicious tomato fritters. Seafood lovers can savor freshly caught fish and seafood dishes, accompanied by locally produced wine and ouzo.
