By far the most spectacular hike on Thira is the 11 km trail along the crater rim to Oia. It offers some breathtaking views over the caldera, and the other islands of the archipelago. At a moderate walking pace, the hike takes about 3 hours. The trail starts northward from Agiou Mina Street and is well-marked; you'll see a few "To Oia" signs before leaving town. Going from Fira to Oia is more uphill, with a climb of over 300 m, so the reverse direction is considered a bit easier.
The story of Akrotiri and other Neolithic and Bronze Age settlements is vividly told through a collection of colorful and artistically-detailed artefacts. Don't miss the collection of vibrant wall murals recovered from Akrotiri.
Museum about the evolution of lifestyle and living on the Santorini archipelago, with displays featuring artisan crafting, a cobbler, blacksmith, distillery, winery, and even a mine underground. All lifestyles from cave houses to modern day typical white dwellings are covered. A guided tour is a necessity to get the most out of a visit, which takes about 45 minutes.
It houses artefacts from Proto-Cycladic culture of the 3rd millennium BC, and continues on to the Classical period.
An ethnographic museum with a collection of maps, landscapes, engravings, and dresses of the Cycladic Islands from the 15th to the 19th century. It is housed in the Megaro Gyzi mansion dated to the 17th century. It also features an exhibition of old manuscripts from the 16th to the 19th century, as well as painting and photographs of Santorini.
Exhibition of work by French artist J.R. Tourte, who moved to Greece before the outbreak of the Second World War and toured the Cyclades until his death in 1972. His work consists of watercoloured scenes of all the major Cycladic Islands along with maps drawn by the artist. Most of the scenes show the authentic islands before they became tourist attractions. The exposition area is in tunnels underground, and are pleasantly cool during hot summer days.
Τρεις καμπάνες των Φηρών
This church famed for its iconic three bells, blue dome, and picturesque views which make it one of the most photographed places on the island. The history dates back to the mid-17th century when two cave churches were built into the-then solid cliff face, but these were destroyed as the cliff receded. An infirmary was built in its place which attracted Jesuits who lived on the site until the land was given to the Diocese of Santorini. The current church was built in 1757 and underwent many expansions and refurbishments, for example in 1958 when it was damaged by an earthquake. Hikers following the Fira to Oia coastal path will pass the Three Bells along their way.
