This palace, located near Seoul's Hyehwa area, is a real treat. It typically draws smaller crowds when compared to the larger palaces in Seoul which is conducive to a relaxing stroll through the palace grounds.
If you visit when it is warm find your way to what is called the Secret Garden, near the back of the palaces grounds, this quiet respite in the city is home to plenty of shade and soothing ponds. Also, keep an eye out for Korea's national bird the Magpie, which seem to really enjoy this area.
