I went here during autumn. There was a place where they changed theme every other month, and the theme was tropicak when I came there, which ironically place where I come from 🤣🤣 So it didn't feel like I was in Korea, but in my home country instead. Overall I love this place. They have different area with different themes, like you can find typical old korean home or typical korean vegetation, but at the same time, you can also find different vegetation from other parts of the worlds (mediterranian climate, etc). So far, I like my time here, good for low-energy sightseeing. They also have cute souvenirs shop
Really beautiful garden in Sejong! There are 3 green houses that you can visit and each one has a different theme and also temperature setting. You can also walk outside in the huge Arboretum park! It was free when we went for lunar new year, so definitely worth it. The green houses section as has a convenience store, cafe, and small businesses selling stuff too
A fantastic day out in Sejong. The arboretum is huge and beautifully planned, with year-round indoor conservatories (Mediterranean and Tropical) plus rotating special exhibits, so there’s always something to see even in bad weather. The outdoor areas are just as impressive—traditional Korean garden spaces and bonsai collections are kept with great care, and seasonal flowers make the paths perfect for photos. Practical notes: general hours are 09:00–18:00 (Mar–Oct) and 09:00–17:00 (Nov–Feb) with last entry one hour before closing, and it’s closed on Mondays—don’t get caught out. On busy weekends or during popular seasonal displays, advance tickets are smart because time slots can sell out. They also occasionally run special night programs, which are worth checking if you’re nearby. Overall: spotless facilities, family-friendly paths, good value, and loads of variety between the greenhouses and outdoor themes. Strongly recommended if you’re anywhere near Sejong!
Stunning building and surrounding area. All for a very reasonable price too. Lots to see and do. Could easily spend half a day there just walking around to see the displays, more if you have interest in botany. Vast space, well used
It’s a huge complex. If you want to see the entire place please go early otherwise you will not be able to cover the whole area. The arboretum closes at 6 pm. There is a huge free parking place. If you are planning to go there please go between April and may to see the tulips at full bloom. Now the admission fee is 5000 korean won per person. We first visited the 4 seasons conservatory. I like all the forests but the special exhibition hall catches my eyes the most as it is so so beautifully decorated. So beautiful to behold. So many cute things to witness. Then if you feel hungry you can eat at the cvs or there are restaurants also. Then we went to the korean lake park area and visited the hanok style houses. Beautiful place to take some rest. You can also buy souvenirs from a shop at the entrance and can also dine at the gourmet. All in one it’s a good place to visit. Don’t forget to check out the pictures below 👇🏻
