While vacationing in Santorini you can witness a phenomenon called "Anedosa" sea fog. It's not very common and it's created when the heat from the volcano mixes with the coolness of the sea. If the wind is blowing from the west you will see a thick blanket of fog covering the caldera and the villages located on the cliff's edge. However when it passes the highest point of the cliff it doesn't crawl downhill, but slowly dissipates and leaves most of the island's visitors to enjoy the sunny weather.
I promise I'll stop with panoramas :) Here's a couple of bunnies...
Thirasia is a small island of the Aegean Sea and belongs to the Cyclades . Until the Minoan eruption that created the caldera in 1600 B.C., it was part of the Stroggyli island.
According to mythology, the island was named after King Thira's youngest daughter Thirasia, to whom he had given the island to build a magnificent palace.
Thirasia has many similarities with Santorini's main island Thira. The architecture of houses and churches, low vegetation and blue-green waters are some of the island's characteristics. Thirasia is an ideal destination for those who want to enjoy peaceful holidays away from crowds.
Riva is the main port of Thirasia. To reach the island you can use the boat that departs from the bay of Ammoudi in Oia and the journey takes about ten minutes. Departure from Ammoudi bay: 08.00, 12.45, 17.20. To get back to the main island from the port of Riva: 07.45, 12.30, 17.10
Thirasia has steep shores and its beaches are small. Guests usually prefer the black beach of Agia Irini, which is near the port of Riva. There is also the beach at the port of Korfos with thick pebbles and pumice. Make sure to bring your swimming shoes! Those who have a boat have far more choices.
The port of Korfos has most of the restaurants of Thirasia, so it gets very busy between 1pm – 4pm because of the boats that take tourists to the volcano and other tours around the island. So if you want some quiet time you're better off planning your trip to Thirasia in the morning.
