I did do a bit of hiking - I did a long walk along Taroko Gorge with a guy called Hsin-yeh. It was lovely, and I remember we didn't get back until the evening. At the end of the walk we hitched a lift from a group of guys going to a place called "East Hawaii". It turned out to be a nightclub! But they kindly drove us into town. What an adventure!
I didn't climb any mountains though. Maybe I'll visit my niece while she's there. (She hates hiking, but then I did when I was her age too!)
