A "free valley" you can visit by subway.

It is extremely hot these days.

It makes you desperately yearn to escape to a truly refreshing valley.

We would like to introduce some great valleys that you can reach simply by taking the subway without having to travel too far.

Have you heard of Sillim Valley in Gwanaksan Eutteum Park in Seoul?

It is being shared on social media as a "same-day valley hotspot" and a "destination for those without cars."

It is gaining word-of-mouth popularity as a new summer retreat not only among local residents but also among the 2030 generation.

Last weekend, the felt air temperature reached 35°C (95°F), and a significant number of citizens visited.

Good shuttle services and proximity to home are cited as its advantages.

In addition, Byeokun Valley can be reached within a 10-minute walk from Exit 1 of Suraksan Station.

Gingorang Valley, accessible by taking a bus from Gunja Station, is also gaining popularity.

Since these locations are public facilities, they are characterized by having no spot fees or time limits on usage.

How about heading out for a refreshing valley outing?
