Honestly, when I first heard about a water park on the Han River, I thought, 'How good could it really be?' But let me tell you, it completely surpassed my expectations!

If you're wondering what to do for a summer weekend getaway, read on! This guide has everything you need to know to make the most of your visit.

⏰ Open Run is a Must - I Lined Up at 7:30 AM and Was First!

If you want to snag one of the prime spots at Gwangnaru Water Park, an 'open run' isn't just an option—it's essential. I arrived at 7:30 AM and was lucky enough to be the very first person in line that day.

By 8:00 AM, people started to trickle in, and by the 9:00 AM opening, a crowd had formed. You'll be waiting about 1.5 hours, but securing a great spot for a comfortable, fun-filled day is absolutely worth it.

You can also book tickets through Naver, but remember they're valid one hour after purchase, so it's smart to book in advance to avoid any delays upon arrival!

💰 Admission Fees - Way More Affordable Than You'd Think!

The admission fees are broken down as follows:

The free admission for children under 6 is a huge bonus! Just make sure to bring proof of age, like a health insurance card or family relations certificate, as it's strictly required. It's best to prepare these documents ahead of time.

🏊 Facilities - Two Main Areas: A Swimming Pool & a Water Play Zone

The park features two main areas: a 3.3-foot deep swimming pool and a dedicated water play zone for younger children.

For the swimming pool, children under 4 feet 3 inches (130cm) must wear a life vest or use a swim tube. Please note that arm floaties are not permitted, so double-check this rule before you go.

If you're visiting with small children, I highly recommend grabbing a parasol spot near the water play zone. It's super convenient to keep an eye on them!

🎯 Best Spots - Insider Tips Straight from the Staff!

Here's a genuine insider tip! The staff working on-site actually pointed out two of the best spots for visitors:

① Six umbrella spots near the snack bar

These are super convenient for grabbing food and drinks, and they offer excellent shade.

② Two umbrella spots next to the men's changing room

While a bit smaller, these spots are quieter and offer a cozy atmosphere.

After your open run, make a beeline for one of these two areas to claim your perfect spot.

And again, if you have young children, the parasols right next to the water play zone are definitely the most convenient. Keep this in mind!

👕 What to Bring - Just These Essentials!

First-timers often wonder what to pack. Here’s a quick list of must-have items:

For **swimwear**, beachwear, rash guards, or athletic shirts are all acceptable. A **swim cap** is required; regular baseball caps are fine, but open-top visors are not allowed. Many people get this wrong, so make sure to double-check!

I strongly recommend bringing **aqua shoes**. If you go barefoot, the ground is pebbly, and it can be quite rough on your feet.

And a **mat or picnic blanket is essential**. If you have camping chairs, they'll make your relaxation even more comfortable.

🍱 Packed Lunches & Snack Bar - Know Before You Go

You're welcome to bring your own packed lunch, which is a great way to save money. However, please note that **alcohol and outside food deliveries are strictly prohibited**.

There is a snack bar on-site offering a variety of items like ramen, tteokbokki, and fried chicken. While the selection is decent, the prices are a bit on the higher side, and the portion sizes can sometimes vary, which was a minor disappointment.

It’s best to manage your expectations if you plan to buy food here, or better yet, pack a hearty lunch to enjoy!

🚿 Changing Rooms & Showers

The changing facilities include separate men's and women's changing rooms, plus a family changing room. The family room is super convenient for those with children.

There are also shower stalls, but it's important to know that **only cold water is available**. This wasn't a big issue during the summer heat, but if you're sensitive to cold water, it's good to be aware of beforehand.

🅿️ Parking Tip - Gwangnaru Parking Lot 2 is Your Best Bet!

For parking, I highly recommend **Gwangnaru Parking Lot 2**. It's the closest lot to the water park, making your arrival and departure much smoother. Just like with the open run, arriving early for parking is a huge advantage. During peak hours, finding a spot can take a significant amount of time, so plan accordingly!
