Antalya, the most popular city in Turkey for tourists, is hosting EXPO 2016, which opened on Friday with the theme "Flowers and Children," with 51 participating countries. There are many things to do in the city and seaside towns to visit.The summer never leaves, but in spring the weather is much more relaxing, and the sea is warm enough for a swim. So if you are on the road to Antalya or are planning a nice vacation before the high season, here are some fascinating activities for you: From diving to rafting to historical tours, Antalya offers many unique experiences for your holiday.Çıralı TownSeparated from the renowned city of Olympos only by a rock, Çıralı has one of the most beautiful secluded beaches on the Mediterranean coast and shares Olympos' Hellenic ruins and historic sites. Çıralı is famous for its flaming rocks, natural flames that burn constantly on a mountainside at the north end of Çıralı village. These eternal flames have been burning methane gas from vents on the rocky slopes for thousands of years. Known as a landmark for ancient mariners passing through the Mediterranean Sea, the flames around Çıralı have died down a bit since antiquity.Even though less remarkable than what the ancients saw, it is still an incredible natural wonder. Don't forget to look up at the sky while lying on the beach. The enchanting Milky Way glides above you as in films, but with a little difference, as you get to see it directly for yourself.How to get there: Minibuses leave from Antalya's main station for intercity buses. After hopping off at the junction on the upland section of the main coastal highway, catch minibuses that depart fairly frequently. Çıralı and Olympos are only half a kilometer from each other, but if you do not want to hop on and hop off during your visit, rent a car and reach the two beaches and discover other natural wonders on the way.Patara BeachPatara Beach has been voted one of the top beaches in the world by Times Online, Best of 2005, and is known as the "widest beach of the northern Mediterranean." Considering its 12-kilometer stretch of white sands, it is not difficult to understand why this beach is the best. Located on the southern tourist spots of Kalkan and Kaş, Patara Beach offers the vivid blue waters of the Mediterranean and the ancient site of Patara. The beach is believed to be the birthplace of Apollo and includes the ruins of western Mediterranean harbors that host ships from all over the world. The beach is also one of the few that loggerhead sea turtles visit to lay their eggs between May and October. Thus, visitors will see caution signs to protect the eggs.Strict building restrictions help make this beach a special, natural wonder. There is only one café on the beach, run by locals, but no big, overbearing buildings: No development, no water sports, only pure tranquility and peace along the coastline of Patara.How to get there: The beach is a 20-minute walk from Patara, but you can also take minibuses to the beach, and beach service buses run from Kalkan and Kaş.Adrasan TownWith priceless landscapes dominating Kemer's historic wonders and uncrowded beaches, Adrasan is a hidden secret of Antalya. An escape from the bustle of Antalya's city center, Adrasan has its own entertainment. While bungalow houses lack the luxury of expensive hotels, they offer guests a friendly, quiet environment. Most bungalows offer half-board, but are ready to meet all your demands during your stay. A boat trip is the perfect way to explore the sea and islands surrounding Adrasan and the city of Antalya. A boat tour costs about TL 40 ($18.65) with lunch included. While on the boat, ask the captain to take you to the "wellness spring," with water believed to have healing properties and the ability to cure illnesses.For an adventure, jump off the rocks when the boat is inside Fosforlu Mağara (Phosphorescent Cave). This majestic cave takes on different colors in the moonlight, and sometimes in the day thanks to its geological structure.How to get there: Minibuses leave Antalya's main station for intercity buses. Hop off at the junction on the upland section of the main coastal highway where minibuses depart fairly frequently to Adrasan or rent a car to discover Adrasan and the little bays around the town.Kekova TownKekova, in the southern city of Antalya, boasts mesmerizing islands.
