A very spectacular route which climbs through forest roads, partially asphalted up to the crater lake “Saint Ann”, followed by a descent through the woods to the lake. We recommend a short break to enjoy the gorgeous image of the lake, followed by a short climb on asphalt, followed then by a short section of walking and pushing your bike. Then a short down-hilling through the forest roads up to the national road at the entrance in Tusnad, where the descent will continue on asphalt to the hotel.
