Sealala Water Park in Seoul is often recommended as a family-friendly indoor water park, but visiting with young children — especially as a solo parent — comes with a few things you’ll want to know in advance. I visited Sealala Water Park with my 6-year-old son during our one-to-one trip to Seoul, and while the experience was fun and memorable, it was also very different from typical family water parks. In this review, I’m sharing our honest experience, including what Sealala is really like for kids, how the gender-separated changing rooms work, helpful tips for parents, and whether it’s worth adding to your Seoul itinerary when traveling with children.

📍 Step 1: Shoe Locker & Entrance
Upon entering, you’ll first receive a receipt with a your locker number on it. Proceed to your locker number locker:
👉 This is used to:
- Lock your shoe locker at this locker
- Pay for rentals, food, and drinks inside (no need to carry cash)
📝 Tip: After locking, Keep this key wristband secure — it’s your key to everything inside.
🧺 Step 2: Changing Area & Gender Segregation
The main changing rooms are gender-segregated, and this is where the onsen (public bath) is located.
For families with kids who can’t enter the opposite gender’s changing area alone (like my 6-year-old):
- The staff will guide you through a staff-restricted passageway to bring your child directly into the water park area.
- I deposited my boy at the lifeguard counter while I entered the women’s changing room to change and rent jjimjilbang clothes.
- After changing, I went back out to the water park to meet him.
👀 Note: It can be a bit of a culture shock if it’s your first time — people are naked in the onsen area, which is normal in Korean spa culture.
🩱 Step 3: What to Bring (or Rent)
we bought his onsite
Compulsory Items:
- 🧢 Swim cap – Everyone must wear one. We forgot ours and had to buy it onsite.
- 🦺 Life jacket – Required for kids under 130 cm. Must rent at the water park.
- 🛟 Tube (optional) – We rented one for extra fun in the pool.
Other Handy Items:
- Waterproof phone pouch 📱
- Towels and toiletries 🧼
- Extra clothes for after your shower 👕
💡 Tip: Locker rentals and gear are all charged to your wristband. You settle the bill when leaving.
🏄 Step 4: Water Park Play Time
Once changed, head to the rental counter inside the water park:
- Rent your child’s life jacket and any tube or float you need.
- Keep your waterproof pouch with your essentials.
⏱️ About Pool Breaks
- Pools operate for 50 minutes, followed by a 10-minute break.
- Lifeguards will make an announcement before each break.
- During this time, everyone must exit the pool.
- Use this break to hydrate, use the restroom, or move between zones.
🛝 Kids Zone
I loved that I could leave my son at the kids pool area in front of the lifeguard station while I took a quick break.
♨️ Step 5: Onsen (Spa) Time for Adults
After a good splash session, I:
- Dropped my boy off again with the lifeguards.
- Entered the women’s onsen to relax for a short while (like 5 minutes haha).
- Showered inside the onsen area before coming out.
👩👦 If your child is old enough to wait safely or has another adult with them, this is a nice time to unwind. I will have to make another trip back with the father!
🚿 Step 6: Family Shower Area
After onsen, we reunited and used the common family shower area to wash up my boy.
🧘 Step 7: Jjimjilbang (Spa Lounge) — Lunch & Nap Time
To access the jjimjilbang:
- We went back through the staff-restricted passageway to reach the lounge area together.
- If you’re of the same gender, you can just access it through the changing area.
🍜 Eating & Resting
- There’s a small canteen where you can order food (just tap your wristband).
- A small kids’ play area keeps little ones occupied.
- You can take a mat and rest on the floors — many families nap here.
💡 Tip: It’s completely cashless inside. Everything is charged to your wristband, and you pay when leaving.
🧳 Step 8: Checkout & Payment
Before exiting:
- Return rented items (life jacket, tube, etc.).
- Pay for your purchases and rentals at the counter.
- Retrieve your shoes from the entrance locker.

✅ My Verdict:
SeaLaLa is super family-friendly once you understand the flow. The staff are used to helping parents with young kids navigate the changing room logistics. It’s a great half or full-day activity — a mix of fun water play for the kids and spa relaxation for the adults.
