Park at the Rührberg hikers' car park (80 spaces) on the edge of the forest between Inzlingen and Wyhlen.
(S/E) With your back to the road, take the path at the far end of the car park on the left for about 100 metres. Join the Red Diamond trail at the next fork and turn right towards Saint-Chrischona in Switzerland.
(1) Just before the border at the "Grenzstein 100" marker, take the path on the right, marked with a yellow diamond. Then take the unmarked path that slopes to the left, runs along the forest and joins the yellow diamond-marked trail a little further on.
(2) Continue straight ahead, cross the fields and enter the forest at the "Nasser Grund" signpost, marked with a yellow diamond.
(3) Continue straight ahead towards Langmatt Farm and Inzlingen. Stay on this path until you reach the next signpost at the edge of the forest, about 300 metres before the farm.
(4) Take the path on the left towards Saint-Chrischona and follow it between the edge of the forest and the Chrischonatal valley until you reach the end.
(5) Continue along Inzlingerweg, straight ahead, and enter the forest. The path follows an "S" shape. Cross two crossroads and continue along Inzlingerweg until you reach the signpost for Saint-Chrischona.
(6) Take the street on the left, then the path on the left towards the church. Go around the church on the right to reach the highest point. Continue to the right, then turn right, leaving the hotel on your left, to reach a five-way crossroads.
(7) Take the second road on the right, then turn onto the small path on the left leading to the restaurant. Take the road on the right to go around it and rejoin the marked path.
(8) Turn left and head towards the TV tower. Continue straight ahead and you will come to the junction you passed on the way there, just after the border.
(1) Continue straight ahead, following the same route as on the way there, until you reach the Rührberg car park (S/E).
