We highly recommend booking online in advance, as this guarantees your entry on the date of visit. Sandcastle Waterpark has a user friendly website which allows you to book your visit in advance and save money when you purchase 7 days or more in advance. There’s also a dedicated desk for guests who have booked online upon arrival at our reception. Remember, if you’ve booked online to make your way to the Internet booking desk when you get here. However, you can also just turn up on the day and pay at reception.
