This is a secret spot, frequented only by Koreans who appreciate night views. Centered around the Han River, it offers a panoramic view of Gangbuk and Gangnam.

Banpo Hangang Park offers fountain shows for a limited time from April to October.

This is a repurposed old Korean warship that can be seen in the park.

This is a unique night view spot where you can see the Lotte Tower, a landmark of Korea, and the surrounding luxurious city at once.

This is a recently opened, large-scale botanical garden cafe. Although it's at least a 40-minute drive from Seoul, it's a truly beautiful, hidden gem popular with Koreans. I recommend it for a relaxing escape from the hustle and bustle of Seoul and a cup of coffee.
