Sealala Water Park — Attraction in Seoul

This was the first indoor water park I visited in Seoul, and it was a total disaster. Took close to one hour just to find parking. Inside, it was insanely crowded — people packed shoulder to shoulder in the lazy river(and that’s about the only thing to do), super noisy because it’s all indoors with too many people, and the water looked really dirty. Hygiene overall was questionable — no sign to ask people to take a shower before entering the water park, even the little sanitizing pool at the entrance didn’t have any water in it.

The water slides were only open for short windows, so there wasn’t much to do. Honestly just felt like a headache from the moment we walked in. Not fun, not relaxing. Never going to this kind of place again in a city as packed as Seoul, especially when they don’t have even have...

An Urban Oasis of Fun and Relaxation SeaLaLa Water Park is one of those hidden gems you don’t expect to find in the middle of the city. It’s not just a water park—it’s a full-blown escape from Seoul’s hustle, complete with warm pools, playful slides, and a jjimjilbang that redefines “chill.”

Whether you’re here with kids, a partner, or just need solo recovery time, SeaLaLa has something for everyone. The wave pool brings the beach to you, the hot tubs melt the stress away, and the sauna zones are clean, calming, and wonderfully therapeutic. Everything’s well-organized and affordable, making it perfect for a daycation.

If you’re craving water therapy and city convenience rolled into one, this is the spot. Bring your swimwear, leave your worries...

This place is too child friendly to the point where it is terrible for adults. The food is subpar and overpriced while the lifeguards take 10 minute breaks every 50 mins, forcing everyone to leave the pool during that time. Every slide is open for a very short time every 2 hours, hats or caps are required and if you try and purchase one good luck because they only have 1 size.

Oh and you have to purchase a towel for the sauna (I have been to 10+ saunas in Korea at this point and have never seen one where you have to pay for a towel)

I don't recommend even if you have kids as this place is overpriced, the facility is old, and it is way too overcrowded even during the weekdays for some reason.

Go to a proper waterpark...
