Guide to Seoul Sky Observatory

Did you know the world’s 5th tallest building is now in Seoul? At 123 floors and 1,821 ft (555 meters), Lotte World Tower is also now the tallest building in Korea. And you can go up to the Seoul Sky Observatory to get views over the whole city! I recently went up courtesy of Trazy, so here’s what to expect if you do too.

Funnily enough, when I first heard about the Lotte World Tower, it was when I was visiting Seokchon Lake during Chuseok in 2015. The building wasn’t even finished yet! It’s actually only been open to the public since 2017, so even when I left Korea the first time, it was still incomplete. Nowadays, you can visit the observatory that spans the 117th – 123rd floors. While it’s a bit pricey for Korea, Trazy does offer Lotte World Tower Seoul Sky discount tickets.

Trazy is an English-friendly booking site for Korea that I often link to. They’re great since they’re based in Korea and often have a ton of discounts or unique tours that other booking sites don’t have.

The Seoul Sky Observatory

While Lotte World Tower is 123 floors, the observatory doesn’t start until the 117th floor. The other levels include everything from office space to residences. Your ticket will get you into all the floors except for the 123rd, which is a VIP-type lounge.

Floor 117

This is the floor you’ll start at! It has views all around the city. I wish they’d keep the windows cleaner, though, as they were pretty dirty when we were there which made the views harder to photograph.

Floor 118

If you want to be able to walk over a glass floor to see just how high up you are, this is the floor to go to. There are actually two sections, and the first one with the mascot is much busier than the other one!

Floor 119

This is the Sky Friends Cafe. I don’t think we really went here, but I did see a Milk Bar on the same floor if you’re hoping to get some dessert.

Floor 120

If you want to go outside, this is the area to do it!

Floor 121

This floor has a bunch of things you can buy related to the tower. I got a cute, illustrated postcard.

Floor 122

The Seoul Sky Cafe is basically an Angel-in-Us, which is a general franchise in Korea.

Floor 123

I didn’t go here, but it’s the 123 Lounge for if you’re feeling a bit fancy and want to splurge. Maybe next time!

Over all I enjoyed the observatory, but I wish the windows were a bit cleaner or you could get views that didn’t have a window. I had the same issue with Namsan Tower, whose windows when I went were tinted blue! Still, the views are spectacular, especially with the cherry blossoms everywhere!

Lotte World

In the same area is one of Seoul’s most popular amusement parks! I wrote a Lotte World guide here if you want to know more.

Seokchon Lake

Lotte World sits on Seokchon Lake, which is especially beautiful during cherry blossom season as the trees all surround the area. You’ll be able to see it all from above in the tower too!
