Stunning palace. I have a lot of time in Seoul and Korea so going to see all the palaces. If your time is limited, definitely do this one. Time your visit accordingly with the mandatory guided tour of the Secret Garden. Annoyingly they appear to change timings so check online the day before your visit. I got there at 09:00 when they opened. I was the first person inside. I walked around the palace grounds myself for just over an hour and then did the English guided Secret Garden tour at 10:30 which finished around noon. Lasts about one and a half hours. You can leave the tour after fifty minutes as the last part is quite a bit of walking including uphill. For most of us it is fine but others were struggling with the heat even though it was early and parts of it are uphill so be mindful. I spent in total three hours there. Separate ticket for the palace and Secret Garden. They do have guided tours of the palace itself but to be honest, you can easily do this yourself. They give you a booklet plus there are information boards. Suggest going early as soon as it opens. It was beautiful and peaceful and you could freely walk around and enjoy the setting, also getting some good photographs. When I left at noon, it was much busier. Grounds are clean and well laid out. The palace was stunning. I loved the details of the doors and the architecture. There is a cafe and what appeared to be an art or souvenir shop on the premises. I didn't bother with it. Take water with especially if you are there for three hours like me. There are restrooms too. My thoughts. The Secret Garden is apparently the highlight. Whilst this was nice, I think the weather will contribute towards your experience. We had a lovely day and the sun shining with the reflection on the water and the colours of the leaves made the gardens look very pretty. However, we can't control the weather and I would suggest thinking about this if you have a day with bad weather. Parts of the garden were nice but other parts started to look the same. I started to get bored as did a lot of the group. I was glad I went though. The guide was difficult to understand (although the tour was in English) but there are information boards as well along the route which also provide useful facts. They limit the number of people on the tour so purchase a ticket as soon as you arrive.
