We detoured south to the Clifden Caves today, since the road to Milford Sound was still closed. We were the only ones at this little known cave system, where the mental challenge by far surpassed the physical -- the saying goes a little something like, 'if your lights die in this cave, you'll die with them.' A bit of claustrophobia and the risk of flash flooding didn't help, but I'd never experienced anything like this before!
