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. It's always best to pack the essentials and avoid bringing items that might get damaged.

At Siam Park in Tenerife, the most common and secure thing to do with your phone is to rent a locker. As of 2026, small lockers cost approximately €7 and large lockers cost €10 (plus a deposit). Because the park features high-intensity water slides with vertical drops, like the Tower of Power, carrying a phone on your person—even in a pocket—is often forbidden for safety reasons. If you want to use your phone for photos during the day, many guests use a high-quality waterproof phone pouch on a lanyard, which is generally permitted on the Mai Thai River (lazy river) and in the wave pool. However, lifeguards will often ask you to tuck the pouch inside your shirt or leave it at the "shoe rack" area before going down the steepest slides to prevent injury. In 2026, the park also offers free Wi-Fi throughout, so if you leave your phone in a locker, you can still quickly check in or upload photos during breaks at Siam Beach without using roaming data.
