The castle ruins are beautiful and have great history behind them, the trails are even more beautiful and the hike on the boardwalk stairs down to the crystal clear fresh spring water is gorgeous. Let's not forget the gorgeous view of the lake! The hike back up is... lets just say you will get your workout in. If you are in the area for any reason it is worth the the trip to see with your own eyes. Something for all ages!! Ruins are handicap accessible as well.Tim Hughes (113)1 year ago3 Completed2 ReviewsVery cool rock formations!Michael Fisher Jr. (130)2 years ago13 Completed2 ReviewsCraig F (596)2 years ago44 Completed21 ReviewsPretty cool short trail.
