Interlaken- Last day

We went out for a traditional swiss breakfast consisting of hasbrown with bacon, herbs, and egg.  I really liked it but the portion was huge... I guess american's are the only ones with big portions ;o) . We decided to go on a walk/hike for a while with a friend from the hostel.  We walked along the river connecting the two lakes.  It was beautiful and enjoyable.  We reached an old ruins castle which wasn't that impressive but a nice surprise along the way.  After a few hours we went back to the hostel to relax a little by playing cards and eatting dinner by the pool.  Then we were off on the train taking a few transfers to Zurich to catch our overnight train to Paris.
