The reward for extra trouble? A beautiful view of the crater (and no wind at the top).
Journey along (acrophobics beware)...

Fifth Station (starting point) at 6:27 AM. Looks like a lovely day.

On the way up at 6:39. Lovely? More like foreboding.

It's 7:52. Say, that looks a little steep.

8:40. Now that's steep!

Three and a half hours of climbing (9:50). No end in sight!

Looking down at 10:22. Is this really a good idea?!

It's 11:56. Almost there!

12:17. Finally made it! Oh look, the huts are closed. :(

Making it all worthwhile!
