We thought this would be worth a visit even though we knew it was closed fur the season and we wouldn't be able to get inside. But a nice winter walk in a beautiful setting with interesting architecture to view sounded like a great way to spend some time. There is a gate that blocks access to even the outside grounds until May. Can see the chapel through the trees but that is all you can do during the winter.
We are sorry you tried to visit when we were closed. However, during the winter months, snow and ice make conditions extremely treacherous on the steep slopes around the chapel. When the weather is dry, we do keep the gate open at times. It is always best to call ahead to inquire whether the gates and grounds are open. Thank you for your understanding.
