While you can bring your mobile phone to Siam Park, it's recommended to store it in lockers available at the park when you're on the rides. This is to avoid any potential damage to your phone from water or during the rides.

At Siam Park in Tenerife—voted the world's best water park—you have several options for securing your phone, though the most recommended is renting a digital locker. These lockers are found near the floating market and the locker villages; they are operated via a waterproof RFID wristband, allowing you to access your device throughout the day without carrying a physical key. For those who want to keep their phone on their person for photos, high-quality waterproof pouches with a neck lanyard are permitted on most attractions, though lifeguards may ask you to tuck the pouch inside your rash guard or life jacket on high-speed slides like the "Tower of Power" for safety. It is important to note that many of the park's more intense slides do not allow loose items, including cameras or phones held by hand. In 2026, many visitors use "smart lockers" that allow for "tap-to-open" access. If you are worried about theft, avoid leaving your phone in an open bag on a sun lounger, as the park is massive and difficult to monitor. The "Locker and Wristband" system is the gold standard for a stress-free day of surfing the "Wave Palace" or sliding through the "Dragon."
