It's no secret that spending an hour or two surrounded by trees and plants can increase your energy. If roaming around town has tired you out, Kazagashira Park is a perfect place to rest your tired legs and recharge your batteries.
This Nagasaki recreation and green space is a good place to kick off your day of sightseeing. There's lots to see in the area, including Glover Garden, Nagasaki Atomic Bomb Museum, and Oura Church. Wander around at your leisure at Kazagashira Park before making tracks to these other fine sights.
