If you'd like some outdoor excitement, make a day trip to Mount Gusuku. No walk around the block, this hike is great for a mid-vacation work out.
This Ie steep landmass is an ideal place to begin your day of sightseeing. There's plenty to do and see close by, like Okinawa Churaumi Aquarium, Sesoko Beach, and Okinawa Hanasaki Marche. Take your time at Mount Gusuku before making tracks to these other fine attractions.
