This is the most amazing castle I have ever visited. I have no idea how they built it, hundreds of feet up on a mountain top, perched above jagged cliffs. We walked up from the village of Duilhac which took us slightly over an hour up to the ticket office, but from there it's another 10 or 15 minutes walk to the castle entrance. Allow at least two hours for your visit and wear good walking shoes as it's a scramble in places. Avoid wet and windy weather. By chance we were there for a falconry display which was an added bonus - it was a very good falconry display too.
