Leading my hearty group on our Best of Europe in 21 Days Tour, we are stacking up the memories -- and that's our goal. Here, we're in Austria's Tirol at the Ehrenberg Castle ruins above the town of Reutte. Imagine the fun I have: hiking with our group up to my favorite ruined castle, then wobbling over the recently built "longest suspension bridge" 300 feet above the ancient Roman Via Claudia, teaching my fellow travelers why the route below us (nicknamed "the salt way") was so strategic in centuries past, explaining how castle architecture evolved with the advent of cannon fire, surprising the group with cold beers once we reach the ruined castle, and then setting them loose amid sword ferns and broken ramparts to let their medieval imaginations go wild.
