Jungfrau

 Today we did an out and back to Jungfrau, which is one of the largest mountains in Switzerland and houses the highest train station in Europe at over 11K feet. We cycled to the base and checked out the waterfall trails.  I didn't count how many we passed, but there were many.  Some people were riding a ski lift to higher ground for observation, some were flying their para sails.  there were also helicopters buzzing around occasionally, so I suppose you could view via helecopter.  There were also several groups of kayakers that we watched navigate the relatively small but very fast moving river paralelling our trail.  Interlaken is an outdoorsy person's dream place, I'm convinced!
