I visited Sareung, the tomb of Queen Jeongsun, the queen of King Danjong, 6th monarch of Joseon. She became queen in January 1454. It's located in Namyangju, which is in Gyeonggi-province just east of Seoul. From Guri or Donong station (on the Jungang Line) you take the bus that says Sareung(or a taxi if you prefer) for a short distance to the tomb area.
There is a botanical garden/nursery at the entrance, where they are growing wildflowers, pine trees, and even some fruit. The people that take care of the nursery give you tea and allow you to take some wildflowers with you if you choose (for tea). They gave us tea to drink, as we walked through the pine forest to the tomb. They had an outdoor photography exhibit set up in the forested area featuring various photographs of wildflowers. After a short walk under the fragrant pines, you come to a clearing where the tomb sits about two-thirds up the mountain. It's a beautiful area and the tomb is guarded by various animals (stone sculptures).
