Definitely not suitable for adults. There were hundreds of kids. Lining up for a slide needed to wait for at least 30 mins. Not worth spending hours to visit there.

So many ppl here today, Friday. Arrived here at 11 pm. I bought ticket from tmon. Pls remember and be careful, I asked the staff there and I clearly said I bought ticket from tmon, but she said I must get waiting number and must get the entrance ticket from the locket! Lucky I tried to check myself. I input the ticket number into the ticket machine, and yes I got the ticket! They need to educate their staffs again!! When we enter the entrance, we ll get locker key that we can use to keep our shoes or sandals and we can use it to pay for something we ate, drank, bought inside. For the most interesting rides here, boomerang, I waited in line for 1 hour! The ride was so short. Not worth the waiting.. one of the staff (guard) even tried to send people who queued alone coz boomerang is a ride for two. The ticket is of course cheaper compare to carribean bay but the scale is also smaller than carribean bay!

No dog sledding even though it shows on the website, so we travelled an hour for nothing. Places is very small, just for little kids. Even on a not busy day it gets full quickly and for the price its better to go to Lotte world or everland. Even with 50% discount it wasn't worth it. Staff refunded quickly. Hopefully they update their website.

Are you watching Love Alarm on Netflix right now? Yep, this is where they shot the skating scenes! There are 2 parks - the snow park and the water park. We were only able to visit the snow park due to limited time. Me and my family went here last June 2018. We had so, so, so much fun!! Helmets and thermal jackets are provided, pick a color! It must be worn before entering the ice for safety. The park is kid and adult friendly. This is our first time skating! Well with sleds, we hope to try the skates soon haha. The entire place is a fortress, with lot of shops, cafés, boutiques, and restaurants around.

A water park and a shopping mall next to each other. In summertime it will probably be packed. Right now it wasn't crowded at all. Decent shopping. Zara and H&M. Some other shops. Bot as crowded as western dome.

One Mount Water and Snow park.. we visited in spring, so just covered WaterPark..Which was absolutely Fun!! Me, my family and friends family went here April 2015..So its long back but I though to review the places where I have been all these years.. so here I am.. So many great memories related to stay in Korea.. and One Mount is one of them...Great great customer support..welcoming staff everywhere..and great discounts for Foreign visitors..And i can say all after this my stay in US...where there is no discounts offered anywhere in such type of parks of wonderlands for Foreign visitors..so definitely it values alot!! Helmets, live jackets are provided, whatever color! It must be worn before entering the water for safety. The park is kid and adult friendly with temperature controlled spas, very fun adventurous water slides which I was initially scared of.. but after first attempt I enjoyed it fully... lot of shops, cafés, boutiques, and restaurants around.

Daiso and shopping but lots of small inexpensive eatery. Outback resturant, found a no brand burger and it is inexpensive and good, price of garlic burger is 2990 won. Found a pet shop too.

The shopping area is recommended for home appliances, fashionable and beauty products

Only the snow sledge is quite fun. The activities are more to small kids.

A place to hang out enjoy with some resto street foods shopping for fashion clothing recreation like waterslides and pools , a snow winter like place in summer experience .. a kids place to enjoy and near beside the aquaplanet lake park and karusokil

A nice place for kids, you may spending half day of time there with joy.

Its fun and affordable. But water was too irritant for skin and eyes

Ice rink, tube slides,huskey ride. good place for small kids only.

I thought sledding for hours and hours would get old but it was actually fun. You can choose between a guided slope you slide down with a partner or a solo freestyle slope. Climbing the many stairs to switch between the two, then waiting in line eats up a lot of time, but the exhilarating trip downhill makes it all worth it. When it does start to wear a little thin, there are several picture zones, a cafeteria with tasty fries and the whole indoor ice rink where you can skate, jump on a trampoline or have real dogs pull you around on a sled (kinda weird but they looked healthy enough).

The place is quite small for only one indoor floor and one outdoor floor with 3 slides. Outdoor floor is opened at 11:00am. People are not too many, so the waiting time is fine around 15-20mins. Tickets were cheaper if bought online. Half day here is fine.

So bad and weird. Everybody wearing strange swimsuits and all have to wear floaties. Even good swimmers are required to wear lifeguard. When you look at the place, you will think what kind of weird scene it is. It is nothing like Europe or america
