The traditional boat Poseidon has been sailing the waters around Symi for 30 years. The daily trip all around the island is something not to be missed. You will see the island from a different perspective and have the chance to swim in crystal clear waters that can only be reached by boat.
The boat leaves the port of Yialos at 10.30am heading for either Maroni Bay or Agios Emilianos for the first stop. Maroni Bay is enchanting, and you can swim off the boat in the beautiful water. Agios Emilianos is a small monastery. This was built with money given by sponge divers after the Saint appeared in a vision to their skipper. It sits on an islet and the boat will moor at the jetty. This allows access to the small gem of a church which is definitely worth a visit. There is also another opportunity to swim.
The second stop is the Seal Cave. The boat will drop anchor here and you can swim into the cave. If you are lucky you may see the resident seal, Mr Alex. He is very shy but if you look carefully you may see his head popping out of the water as he has a look around at the visitors to his domain.
The next swimming stop will be either the Diavates Islands or Agios Vasilios Bay depending on the daily schedule. The Diavates is a group of small islands and once again the anchor will be dropped allowing you to swim off the boat. Agios Vasilios Bay is one of the most picturesque beaches on the island and you will enjoy a swim in the crystal-clear water. If you wish you can swim to the beach for a bit of beachcombing.
The fourth stop is always the island of Seskli. This is where you have a longer stop of 2 ½ hours and enjoy lunch. While the crew are barbequing the chicken and preparing the rest of the food, you can enjoy time on the beach, have a swim or
explore the small island. Lunch is a feast of freshly prepared food and there is a seating area under the trees where you can relax in comfort while eating and enjoy a glass of wine.
The last stop on the way back is the magnificent Agios Georgios Bay. The water here is truly aquamarine. See if you can spy the Greek flag painted high up on the cliff face.
The experience is completed by arriving back at the beautiful port of Symi having enjoyed an unforgettable day.
Don’t forget to bring your sunscreen and sunglasses :)
Protect your skin and the sensitive marine ecosystem by using reef-friendly sunscreen during swims.
Wear water shoes for rocky shore access and bring goggles or snorkels to enhance your swim experience.
The boat departs promptly at 10:30 am from the port of Yialos; arriving early ensures a smooth boarding process.
Bring quick-dry clothes for comfort after swimming stops and the BBQ lunch break on Seskli Island.
The monastery of Agios Emilianos was built following a vision experienced by a local sponge diver’s skipper, underscoring Symi’s deep connection to maritime traditions.
