At the end of this second straight road, ignore the bridge on the left and turn right onto the path that enters the undergrowth.
(2) Climb through the woods, staying on the path as the woods are private property. At the edge of the woods, the path continues to the left and follows the edge of the forest.

(16) At the edge of the woods, turn left and follow the edge until you come to a path that leaves the woods and heads off to the right. Follow it to the right.

(19) Turn right onto the departmental road and continue to the next crossroads. Turn left onto the dirt track that climbs up into the Bois des Arramous. Continue along this track until it bends to the left.
(20) Turn onto the path on the right, cross the field, and descend along the edge of the woods. At the bottom, take the path on the right that enters the woods. The path follows a stream and passes through patches of relatively tall bamboo before emerging into the open air.
(21) At the edge of the bamboo forest, the path continues uphill, following the edge of the woods on the left. When the woods bend to the left, follow the path diagonally to the carriage road, then turn left. Continue to the crossroads where there is a bench.
