If you’d like to see a whole new side of Hangang River, we recommend visiting at night. You’ll find that the atmosphere is totally different. You might wonder, “What exactly is there to do in the dark?” Below are two nighttime-only activities you won’t want to miss.

One thing that tourists absolutely can’t pass up is the river cruise and fireworks show. Romantic moments aboard the cruise ship have even been featured in K-dramas like What’s Wrong with Secretary Kim and Lovely Runner, involving the main characters. Unsurprisingly, the cruise is also a popular destination for couples in love.

Most Hangang River cruises depart from Yeouido Hangang River Park. As the ship slowly meanders through the river, the lights and waves that dance on the surface of the water create a vibe that is completely different from what one sees during the daytime. Fireworks shows are included in the evening hours, and watching them explode against the city skyline makes the summer night even more magical.

Before or after your cruise, you wouldn’t want to miss the nearby Seoul Bamdokkaebi Night Market. It’s a night market that opens only during the warmer months, and features food trucks, handicraft stalls, and live performances across the Hangang River Park.

The easiest way to cool off in the summer heat is to enjoy the many water activities offered by the Hangang River for dynamic summer fun. Korean variety shows like Running Man and 2 Days & 1 Night have featured all kinds of riverfront adventures. Now you can try them yourself!

Among the many parks, Ttukseom Hangang River Park stands out for its wide range of water sports. During the summer months, you can head to its waterfront activity zone and try paddleboarding, kayaking, and windsurfing. Most of the programs are short one-day sessions under two hours, so they can easily fit into even the most jampacked itineraries.

Scared of the water or not a fan of water sports? Even beginners are welcome, and you don’t need your own gear. Equipment rentals are available on site, and friendly instructors will walk you through everything. Besides, unlike the ocean, the Hangang River’s currents are calm, and the activity zones are well-equipped with safety staff and gear, so you needn’t worry.

If you're hoping for an escape from the everyday, a small reprieve from the stresses of the city, you want to try the water activities at Hangang River. Instead of hiding in the shade, why not meet summer head-on?

The highlight of every Seoul summer has to be the Hangang River Festival. And in 2025, it’s back and better than ever, under this year’s theme “Cool Cool Hangang River.” The festival takes place across 11 major Hangang River parks including Yeouido, Ttukseom, Mangwon, and Nanji, so it’s easy to swing by whichever spot fits your schedule or route.

There’s no shortage of things to do, from cultural events like a Silent DJ Party and an Under-the-Bridge Film Festival to a Build-Your-Own-Raft boat race. Sports programs like Hangang River Night Walk 42k and a Mood Rooftop Yoga Class and Dinner will appeal to fitness aficionados. Visitors can choose what best fits their energy levels and interests.

Most of the events are free, and many don’t require reservations and are open to walk-ins. This means that tourists on an itinerary can also show up and join in without worrying about planning ahead. It’s a great way to spend a full day of activities and fun!

If it’s not clear by now, you absolutely must stop by Hangang River if you’re visiting Seoul. It’s one of the best places to truly experience the city. It’s rare to find a place that has it all, from the riverside parks, the picnic culture, the water sports, the night markets, the cruises, and the nightscapes. If you want to fully soak in the vibes of a Seoul summer, Hangang River is the place to be.
