Are you up for a hike? I wasn't when I realized that this famous "Koko Crater Trail" has 1,048 steps to the top! But I can show you what's possible on this gorgeous island; feel free to send me pictures from the top.
Apparently the railroad tie trail is the remains of a funicular track that carried men and supplies up to a radar facility on top of the crater during World War II. The view is said to be spectacular and is a fun milestone activity for those who like a physical challenge on their vacation.
