The Inebolu - Kastamonu minibuses cross over the Cuhadurogu pass (I will put in correct Turkish later, and this is from memory) at 996 meters. There is this tea house, where I will drink a number of glasses before hitting the road. One road is visible, the one to the right. It offers the opportunity to push on, into a nice valley, or to go left after a short while, and descend into another valley, that contains the "old Kastamonu road". Wonderful. But there are more options....
