Yes, water shoes are highly recommended for Mallorca in 2026, specifically if you plan to visit the island’s famous "Calas" (coves). While popular beaches like Playa de Palma or Es Trenc have soft, fine sand, many of the most beautiful spots—such as Cala Deia, Cala Llombards, or Sa Calobra—are incredibly rocky or made of pebbles. These rocks can be very sharp and are often covered in sea urchins, which are painful to step on. Additionally, the limestone rocks surrounding the water can become extremely slippery and hot in the summer sun. Having a pair of lightweight, grippy water shoes allows you to scramble over rocks to find a private spot and enter the water safely without fear of cuts or stings. In 2026, you can buy these at almost any "Souvenir & Beach" shop in tourist towns for about €10–€15, but bringing your own ensures a better fit for hiking between coves.
