Caribbean Bay is the largest and most famous water park in South Korea. It is located in Yongin, right next to Everland theme park. It features thrilling water slides like Mega Storm, a giant wave pool, and a lazy river to relax in. There are also large indoor pools and warm spa facilities so you can enjoy yourself whether it is too hot or rainy. The park is kept very clean and safe with plenty of lifeguards on duty. However, if you go during the peak summer season (July and August), it gets extremely crowded, and you may have to wait 1 to 2 hours in line for rides. It takes about 1.5 hours to reach from central Seoul, and extra fees apply for locker and life jacket rentals. If you pre-book your tickets online and go early in the morning, you can avoid the crowds and have an incredible time!
