извините не подскажу, прежде чем ехать я из дома ищу гостиницы, простите, каждый по своим деньгам расчитывает

Hello, Yeouido Park has inline skate rentals and it's close from Yeouido Hangang Park. They say 3,000 won for one hour.

It’s where you can see the Banpo Beidge light show, picnic. Normal park things. It’s a good place to relax!

Hello, I recommend you to walk from City Hall until Gwanghwamun metro station (line 5, violet color). From that station you need to travel about 15 minutes, only 6 stops. Get out at Yeouido station, exit 2 and you are in Hangang Park.

Hi! I Seoul U sign is in Yeouido Hangang Park. You can see Yeouido Park and Yeouido Hangang Park together as they are linked through a tunnel. If you have limited time, Hangang Park is more recommended as it is closer to the metro station, bike rental shop and you can enjoy the Han river(Gang in Korean) view with many buskers.

I think there are 12 parks with name Hangang. Yeouido is one of them, relatively larger and nicer. Many activities are possible. Nowadays it is festival time there, blossom festival.

Yeouinaru station, exit 2 or 3

Yes, many people enjoy jogging!

I did not fly a drone when I was there - so I am sorry, but I am unable to answer your question about the drone.
