Swimming may be prohibited.
After you enjoy the amazing photos of the beaches on the website of the hotel you like, find out in advance if guests are actually allowed to swim in them. Maybe there are some underwater currents that make it impossible to swim safely. Additionally, the quality of water in all the resorts is checked every year and the beaches are marked with special blue flags if the water is good and a black flag in the opposite case. The latter are often the beaches where tourists leave a lot of trash. Either way, you should definitely find out the status of the beach you’re going to go to.
