After letting Joy play on the beach a little, Guo-Yen, HL Joy and I rented some bikes. We rode to the ferry and crossed back to the main island. We ate some good flavored ice there and rode around the small harbor.
On the next day Dad, HL, Joy and I rented bikes and explored some more. We rode north until we reached the Chijin Star Tunnel. There are stars and constellations on part of the ceiling of the tunnel that glow. We walked through the tunnel and up a path to a lighthouse. After the lighthouse we walked to the ruins of an old fort.
