nice climb up to the intersection...then the road going to the fort is cleaner depending on the day (twigs, bread needles...)

The castle is not open to the public. It's a shame, as the site is exceptional. The earliest remains date back to the 14th century, when the castle was owned by the Bishop of Grenoble. Today, it is privately owned.
