The island is great for a trip outside the city. A relaxed trip along the promenade on the waterline is a great opening for a visit here. Later on, you can rent bicycles and ride along the harbor.
You can also spend some leisurely hours on the beach, in the alleyways and the harbor. You can always spend your time at the pleasant cafes, eating seafood in fantastic restaurants on the island and seeing the locals and how they live. These, by the way, are nice and sweet people. They are always happy to hello, even with their broken English.
