This royal winter palace has lavishly landscaped gardens and is open to the public. Dress code strictly applied: dress modestly or pay 15 baht for fisherman's pants to cover your lack of it. This includes ANY leg above the ankle for either gender). The palace itself (built in 1961) is not particularly exciting, but the extensive gardens are picturesque with some amazing plant life, including carefully tended tropical flowers, centuries-old trees and giant bamboo. A sign at the bottom of the hill near the zoo indicates when it's closed. It is close to Wat Prathat Doi Suthep, so travel directions are similar.
