my daughter and I visited Chillon Castle on a Sat morning, which was peak tourist time, but the earlier Yiu go the better an experience you should have. The size scale and diligence of the preservation that has gone into the Chateau, as well as the history of its existence both are truly amazing!, I could only imagine living. Inside, during one of the many sieges and having to exist and survive - plus fight off the occasional horde of amp gray invaders!! Wow - plus the views across the lake on a clear day are awesome!!
Do give yourself several hours to enjoy, appreciate and reflect on life back then...it is worth it!! And take lots of memorable photos (go stand inside the dining room fireplace) !! More
