Izu Cape Lighthouse is just one of the landmarks located 1.6 mi (2.5 km) from central Miyakejima, so you might want to stop by for a few pics during your trip.
If you can't wait to get to the beach, you might enjoy a trip to Takowan Beach located 1.2 mi (1.9 km) from central Kozushima-mura. Enjoy the sunset by the shore at Maehama Beach.
