Planning some water fun in Jeju during summer?
Most people think of the beach first,
but honestly, a natural swimming spot with clear, cool freshwater can be just as tempting.
And if it’s a place you can enjoy comfortably without that sticky, salty seawater feeling—nothing beats it.
Today’s pick is in Yerae-dong, Seogwipo, Jeju:
“Nonjitmul Freshwater Pool”,
a natural swimming spot locals love as a hidden summer getaway.

This is a natural spring-water coastal area where clear water flowing down from Hallasan meets the sea, creating a unique natural setting. It was once called “Nonjitmul,” meaning the spring water that used to flow out as agricultural water was simply let run; today, it is used as a natural freshwater pool operated in summer. Because it sits right next to the ocean, you can feel both freshwater and seawater at the same time. With relatively shallow depth, it’s also a popular spot for families to enjoy playing in the water. Nearby, Yerae Coastal Road and sections of the Olle Trail connect through the area, making it great for a walk or a drive. It’s also close to the Jungmun Tourist Complex, making it easy to visit together.

Nonjitmul Freshwater Pool is a natural pool created as spring water (yongcheonsu) bubbling up from underground
flows toward the coast and mixes with seawater.
Thanks to the freshwater’s clear, chilly temperature,
even in peak summer, the moment you step in, a refreshing coolness spreads through your whole body.

Because it’s structured as if it connects to the sea,
the wide-open view feels like an infinity pool—a major plus.
In particular, the water color looks especially beautiful in the afternoon sunlight.
Free admission—one of the best-value water spots
One of the biggest draws here is that there’s no entrance fee.
There is a small charge if you use seating spots like parasols, shade tents, or platforms,
but the fees have been adjusted to be much more reasonable than before, so it’s easy to enjoy without 부담.
It’s also a comfortable place to spend the whole day with kids.

Plus, at certain times you’ll see streams of water pouring down like a fountain,
making it perfect for kids to run around and play!
If you’re looking for water fun that feels close to nature, this place is a great fit.
Nonjitmul Freshwater Pool with basic conveniences
At Nonjitmul, there’s a public restroom,
so you won’t have trouble with the basics.
Near the entrance, there’s also an open-air bath-style rinse area,
where you can quickly pour water over yourself even with your clothes on,
but it’s not a full shower—keep that in mind.
