Pink Beach
In Hana there is this Pink Beach, which provides a nice sheltered swimming area- if you can find it. Luckily the guide books describe the path well. Basically you have to park and cut across a community center field, pass the old Japanese graveyard that is now slowly falling into the sea, and then walk a short way on the steep side of the peninsula. Once you get there you find a nice private beach cut out of the pink dirt peninsula, popular with the nudists (thus no photos of the actual beach) and other people searching for a quite place to relax.
