Daheeyeon Garden (formerly known as Gyeongdeokwon) is a major tea farm on Jeju Island, which has the best conditions for growing great tea in a natural environment. Jeju has a year-round average temerature of 16℃ and nutrient-rich soil with plenty of water for the tea plants to grow well. The two cave cafes, Evergreen Luce Garden and Eve Hall, serve naturally fermented green tea bread, cookies, muffins, green tea latte and green tea juice.
Evergreen Luce outdoor garden was built inside a cave formed naturally by a volcanic eruption. Despite being in a cave, this outdoor garden has ponds, bridges, indigenous trees and flowers. Eve Hall is located through a hole in the cave ceiling and can be only reached after passing through a tunnel-like cave. The deepest part of Eve Hall is roughly 30 meters and is home to bats; if you are lucky, you might even see a few.
