Things to Do in Jamsil (2026): Lotte World, Seoul Sky, Seokchon Lake and Olympic Park

Short answer: in Jamsil, spend a day at Lotte World Adventure or go up Lotte World Tower to Seoul Sky, then walk around Seokchon Lake as the lights come on. If you’d rather skip the ticket prices, Olympic Park and the Seoul Baekje Museum next to it are huge, green and free.

Jamsil is in Songpa-gu, in southeast Seoul, and almost everything here sits around one subway station. Lotte owns a big piece of it: the theme park, the tower, the aquarium and the mall all connect underground. A short ride east, Olympic Park covers the grounds of the 1988 Games and a fortress built about 1,600 years earlier. Below are the eight places worth your time, with 2026 prices and hours from the official websites.

1. Lotte World Adventure

Why go: It’s Seoul’s big theme park, and it works in any weather because most of it is indoors. The outdoor half, Magic Island, sits on Seokchon Lake with the castle you see in every Jamsil photo.

• What to do: Rides and parades indoors, then cross to Magic Island for the outdoor rides and lake views. The combined ticket also gets you into the Folk Museum (see #7).
• Getting there: Jamsil Station (Lines 2 and 8), Exit 4
• Hours: Opens at 10:00. Closing time changes by date: in late October it’s 21:00 on weekdays and 22:00 on Fridays and Saturdays. Ticket sales and entry close one hour before closing. Hours for November weren’t posted yet when we checked.
• Cost: The combined ticket (park plus Folk Museum) is ₩67,000 for adults (about US$50), ₩58,000 for ages 13–18 (about US$44) and ₩50,000 for children aged 36 months to 12 years (about US$38). The After4 ticket, for entry from 4 p.m., is ₩55,000 / ₩47,000 / ₩39,000 (about US$41 / 35 / 29). A park-only ticket is a little cheaper: ₩64,000 for adults, ₩52,000 After4. Visitors aged 65 and over pay the child price.
• Tip: Games and some extras cost more on top of the ticket. Some Magic Island rides stop in very hot or cold weather, strong wind or heavy rain, so check the park’s “Today’s Park” page on the morning you go.

2. Seoul Sky (Lotte World Tower)

Why go: Lotte World Tower is the tallest building in Korea, and Seoul Sky fills its top floors. On a clear day you can see most of the city, the Han River and the mountains around Seoul.

• What to do: Ride the elevator up, then walk the observation floors and the glass-floor section. Brave visitors can book the Sky Bridge Tour, a guided walk on a bridge outside near the top of the tower.
• Getting there: Jamsil Station, Line 2 Exits 1 or 2, or Line 8 Exits 10 or 11
• Hours: Opens daily at 10:30 and closes at 22:00 Sunday to Thursday, 23:00 Friday and Saturday. Entry closes one hour before closing.
• Cost: ₩33,000 for ages 13 and up (about US$25), ₩29,000 for children aged 36 months to 12 (about US$22). Under 36 months enter free with a guardian. The Seoul Sky + Aquarium package costs ₩62,000 for adults (about US$47) and ₩56,000 for children and seniors 65+ (about US$42).
• Sky Bridge Tour: ₩130,000 (about US$98) including observatory entry. Tours run at 13:00, 15:00, 17:00 and 19:00 Monday to Thursday, and every hour from 13:00 to 19:00 Friday to Sunday and on holidays. Each tour takes about an hour with up to 12 people. Age and height limits apply. The Sky Bridge closes for winter from November 30, 2026 to February 28, 2027.
• Tip: Go about an hour before sunset. You’ll see the city in daylight, at dusk and lit up at night on one ticket.

3. Lotte World Aquarium

Why go: If you’re traveling with kids or it’s raining, start here. It’s on the lower floors of Lotte World Mall, so you never have to step outside.

• What to do: Walk the tunnel tank and the themed zones, and catch a feeding session if the timing works.
• Getting there: Jamsil Station, Line 2 Exits 1 or 2, or Line 8 Exits 10 or 11
• Hours: Opens daily at 10:00. Closes at 20:00 Monday to Thursday and 22:00 Friday to Sunday. Entry closes one hour before closing.
• Cost: ₩37,000 for ages 13 and up (about US$28), ₩33,000 for children aged 36 months to 12 (about US$25). Under 36 months enter free.
• Tip: If you’re going up Seoul Sky too, the combined package (₩62,000 for adults) costs less than buying the two tickets separately.

4. Seokchon Lake

Why go: Jamsil locals come here for their evening walk. The lake is split in two by a road, and a flat path of about 2.5 km circles both halves, with Lotte World Tower reflected in the water.

• What to do: Walk or jog the loop, watch Magic Island light up after dark, and look out for art installations. Big inflatable artworks have floated on the lake before.
• Getting there: A few minutes’ walk from Jamsil Station. The lake is right behind Lotte World Adventure.
• Cost: Free
• Tip: In early April the lake is ringed with cherry blossoms. It’s one of Seoul’s most famous blossom walks and gets very crowded on weekends. The east lake (the side away from Lotte World) is usually quieter.

5. Olympic Park

Why go: Built for the 1986 Asian Games and the 1988 Seoul Olympics, the park is so big that Seoul people come here to picnic, cycle and walk off a whole afternoon. It also holds Mongchontoseong, an earthen fortress from the Baekje kingdom.

• What to do: Start at the World Peace Gate, walk the grassy walls of Mongchontoseong, and find the “Lone Tree” (나홀로나무), a single tree on a grassy hill that Koreans love to photograph. The park is also full of outdoor sculptures.
• Getting there: Mongchontoseong Station (Line 8), Exit 1, for the World Peace Gate side. Olympic Park Station (Lines 5 and 9) and Hanseong Baekje Station (Line 9) are also close.
• Hours: Open all year. On foot or by bike, you can enter 05:00–22:00. The plaza areas stay open until 24:00.
• Cost: Free
• Tip: It’s a big park. Pick one side to explore rather than trying to see it all, and wear comfortable shoes. Concerts are often held at the venues inside, so check what’s on if you want a night out.

6. Seoul Baekje Museum

Why go: Long before Joseon made Seoul its capital, the Baekje kingdom ruled from this exact spot. This museum on the edge of Olympic Park tells that story clearly, and it costs nothing.

• What to do: See the cross-section of a Baekje earthen wall, artifacts dug up in Songpa, and the exhibits on Hanseong, Baekje’s first capital.
• Getting there: Hanseong Baekje Station (Line 9), Exit 2, about 5–6 minutes on foot. From Mongchontoseong Station (Line 8), Exit 1, it’s about 650 m, or a 10–15 minute walk.
• Hours: 09:00–18:00. Until November 30, 2026, it stays open until 21:00 on Tuesdays, Wednesdays, Fridays, Saturdays and Sundays. Closed Mondays and January 1. When a Monday is a public holiday, it opens as normal.
• Cost: Free
• Tip: Visit the museum first, then walk out to Mongchontoseong in the park. The fortress walls make far more sense once you know what they are.

7. Lotte World Folk Museum

Why go: It’s inside Lotte World, so most visitors walk right past it. It’s worth stopping for: a quick, visual tour of Korean history through miniature villages, models and reconstructed streets.

• What to do: Walk the timeline from prehistory to the Joseon dynasty. The miniature village scenes are the highlight.
• Getting there: Jamsil Station, Exit 4, inside the Lotte World Adventure building
• Hours: 11:00–19:00 every day
• Cost: Included in Lotte World Adventure’s combined ticket, but with that ticket you need to enter the museum by 18:00. On its own it costs ₩5,000 for adults (about US$4), ₩3,000 for youth and ₩2,000 for children.
• Tip: If you’re buying the combined Lotte World ticket anyway, fit this in before 18:00, since entry is already paid for.

8. Lotte World Mall and Lotte Museum of Art

Why go: The mall at the foot of Lotte World Tower links the tower, the aquarium and Jamsil Station underground. It’s where you’ll end up eating, shopping or waiting out the rain. The Lotte Museum of Art in the tower brings in large contemporary art shows.

• What to do: Browse Korean and international brands, eat in the restaurant floors, and check what’s showing at the museum.
• Getting there: Jamsil Station, Line 2 Exits 1 or 2, or Line 8 Exits 10 or 11
• Hours: The Lotte Museum of Art is open Monday to Sunday, 10:30–19:00 (last entry 18:30).
• Cost: Free to browse the mall. Museum tickets depend on the exhibition. The current show, Lee Kang-so, runs until November 1, 2026 and costs ₩20,000 for adults (about US$15).
• Tip: The museum hadn’t announced its next exhibition when we checked, so look at its website before planning a visit after November 1.

Jamsil Tips

• Check your exit. Jamsil Station is huge. Lotte World Adventure uses Exit 4. Lotte World Tower, Seoul Sky and the aquarium use Exits 1–2 on Line 2, or 10–11 on Line 8.
• Watch the late nights. Seoul Sky stays open to 23:00 on Fridays and Saturdays, and the aquarium until 22:00 Friday to Sunday.
• Mondays: The Seoul Baekje Museum is closed. The Lotte attractions stay open.
• Baseball: Jamsil Baseball Stadium is home to two KBO teams, the LG Twins and the Doosan Bears. If you visit in season, a night game makes a good evening out.
• Use Naver Map. Search the Korean names (롯데월드, 서울스카이, 석촌호수, 올림픽공원, 한성백제박물관) for accurate walking routes.
