The water is cold and refreshing. There are lots of shade from trees and places to rest, so it's great to put your feet up and play. Get off at the station and go up for 15 minutes to reach the valley. It's worth a visit to beat the heat. ^^/

Perhaps because there was no rain, the water in the valley has decreased. I had a good time today.

The valley is long and large, so it's great for playing in the water with kids. There are a lot of people and there are a lot of trees, so it's perfect for enjoying summer while avoiding the sun. There is a shortcut hole in the parking lot inside Seoul National University, but there is a lot of barbed wire, so enter carefully.

There are a variety of trails and the course is long, so it's good to take multiple paths. I'm satisfied because it's good to go with pets!

It is a valley that flows between the Gwanak Mountain (⛰) Natural Park trail and the Seoul National University (🏫) Gwanak Campus. However, as of the date of visit, a no-entry sign (🚫) was erected at the beginning (downstream) of the trail due to safety concerns. You can freely enter and exit from the valley (middle stream) visible after passing Gwanaksan Lake Park, and you can often see various birds, including ducks (🦆), here. If you continue up the hiking trail, you will see cleaner and wider valleys (upstream), and here you can freely play in the water within a safe range. Please note that you need to be careful as there are slippery rocks on the floor, and snakes (including venomous snakes) may appear nearby, so be careful!

It wasn't raining much in August, so the E. coli count was over 800. So I told them to just dip their feet, but everyone even soaked their faces. And they brought their dogs into the valley water, but even though the lifeguard said they couldn't, why didn't everyone do it? There was no water, the water quality was bad, and it smelled.

Don't ever come!!! As it was raining and the water was suddenly released from the outlet, I came here with my kids and we almost got carried away. The water in the valley rose so quickly that we got stuck and almost couldn't get out. It's too dangerous. There aren't any safety facilities. Don't go!!!!... .

It's so nice to be in a world where you can take the subway and go to the valley!! When you get off at Gwanaksan Station, the last stop of the Sillim Line, you will see the main gate right in front of you. If you walk along the road, you will reach the very long and shallow Sillim Valley!! Also, Gwanak Rest Area was recently opened at the exit of Gwanaksan Station, so there are Kim Seon-saeng Gimbap, Yellow Chicken, and CU convenience stores~ If you come empty-handed with a credit card, buy food at the entrance and head to the valley^^ “You can really enjoy all these luxuries in the middle of Seoul!” “This place is like heaven~~” This is an admiring conversation from my children haha.
