Head to the Liliental car park. Coming from Ihringen, head towards Wasenweiler. Just before Wasenweiler and a chapel, turn left towards Lilienhof.
(S/E) From the car park, head towards the Zur Lilie inn. Pass the information boards and a fountain on your right. Then follow the signs for Schützenhaus/Ihringen/Knabenkrautpfad down a slight slope on a small asphalt road (Mühlentalweg). At the first intersection, just before a small pond, leave a wide uphill path on your left and turn right (Nordic Walking sign). Pass to the right of the pond and, about 50 metres after starting the climb, you will reach an intersection at a place called Unterer Fischweier.
(1) Ignore the path on the right towards Mühletal and turn left uphill towards Hohrain/Gagenhart. At the end of a steep climb through a beech forest, having first passed a logging track on the right and then, almost at the top of the climb, a path on the left (which does not appear on the map), continue straight ahead until you reach Gagenhart.
(2) Take the path furthest to the left, heading north towards Hohrain. Leave the path on the right towards Kastanienplatz and the path opposite leading downhill (no direction). Pass to the left of a telephone antenna. About 50 m further down, at an intersection, continue to the right, guided by the yellow diamond, leaving a path leading off to the left. On a downhill section, ignore a steeply descending path on the right and stay on the wide path. You will come to a path coming from the right from Hohrainbuck-Hütte at a place called Hohrain. Continue straight ahead towards Gagenhartwald and you will come to an intersection at a place called Hasenbeinmatte (just before the large intersection, ignore the small shortcut on the left).
(3) Leave the path opposite towards Altvogtsburg and turn left towards Gagenhartwald. About 20 metres further on, ignore the wide downhill path and turn right towards Neunlinden, marked with a yellow diamond. After a short climb, cross a path coming from the right at Gagenhartwald and turn left (yellow diamond) towards Herrenweg/Neunlindenturm on the Neunlindenpfad path. At a boundary marker, ignore a path coming from the right. At the intersection at Herrenweg, turn right onto the Kaiserstühlpfad path uphill towards Neunlindenturm. Leave the Adlerhorstattel direction on your left. After a steep climb, you will arrive at Neun Lindenturm.
From the top of the small tower, there is a superb panorama from Belchen to Kandel and the Vosges behind the transmission tower on Totenkopf.
(4) From the foot of the tower, head towards Oberbergen/Liliental on Chemin Neunlindenpfad. A few metres after the small tower, ignore a small path on the right and continue downhill to the left on a wide path to reach an intersection at Beimneunlindenturm. Leave the path leading up to Totenkopf (transmission tower) and ignore the path on the right leading down to Dreieckiger Bannstein, taking the path on the left towards Adlerhorstsattel. At the fork in the descent, take the path on the right as it is less "stony" than the one on the left. At Adlerhorstsattel, you will find a wide path coming from the right. Continue straight ahead towards Adlerhorsthütte/Gierstein and after 50 metres you will arrive at a wide intersection at Adlerhorstsattel/Nord-Süd Weg (information boards, table and benches).
(5) Ignore the two paths on the right (towards Rossläger and Chemin Daglebuchweg) and the one descending to the left, and continue straight ahead until you reach a fork 50 m further on. Take the right-hand path towards Gierstein/Lenzenberg on Chemin Neunlindenpfad, ignoring the path on the left towards Adlerhorsthütte/Liliental. At the bottom of a descent, after several hundred metres, you will come to a path leading to Bickensohl.
(6) Continue straight ahead uphill, following the yellow diamond, leaving Bickensohl on your right and the two small paths on your left (one of which leads to Liliental). After about 1 km, at a place called Gierstein, ignore the path on the right towards Bickensohl and continue straight ahead downhill on the Neunlindenpfad towards Lenzenberg Gasthaus. Arrive at Lenzenberg.
(7) Turn left towards Sauwasen/Himmelburg. About 50 m further on, just before a wide circular bend to the right, ignore a path branching off to the left and turn right towards Ihringen (yellow diamond). After 30 m on the paved path, just before a shelter on the left (tin roof) and a metal gate on the right, you will come to a junction with a small path leading downhill to the left.
(8) Do not miss this small path. Note that this path only appears partially on maps. Take this path and do not try to enter the vineyards, but follow the path marked with a yellow diamond. After about 100 metres of descent along the edge of the forest, you will come to a wide cross-path. Take this path on the left, which climbs slightly. Continue along this path between the forest and the vineyard. You will come to an intersection with a path leading down to the right at a hunting lookout.
(9) Leave the path running alongside the forest and turn right onto the sunken path. A few metres further down, ignore a path leading off to the right. Pass to the right of a small hut in the middle of the vineyards, which is ideal for a short break.
Follow the yellow diamond on the wide carriageway, ignoring the paths leading into the vineyards, and arrive at the junction with a small asphalt road at an intersection near some houses, at a bench and a "Himmelburg" marker.
(10) Do not continue down the road, but turn left onto the path going uphill. After about 100 metres, turn right and leave the path opposite that goes uphill. Continue through the vineyards, enjoying the view between the Black Forest and the vineyards, and just before entering the forest, leave a path on the left and a steeply descending path on the right. Continue straight ahead until you reach a fork.
(11) Be careful not to continue straight ahead uphill, but turn right down a slight slope onto the barely visible path (yellow Rundweg sign slightly below). At the bottom of the descent, ignore a path on the right going uphill at the corner of an enclosure. Go past the gate of this enclosure, follow it for about 20 metres and you will come out onto a wide path. Turn left uphill. About ten metres further on, take the small path on the right, leaving the wide path at the edge of the forest. After a short climb, ignore a path coming from the left (not shown on the map), and a few metres further on, at a bench, you will come to a junction with a wide carriageway.
(12) Just behind the bench, take the path furthest to the left (yellow diamond) towards Neunlinden and leave the direction of Lilienhof. At Unterer Wetzentalweg, find a wide path and take it to the right, towards Hüttenweg/Gasthaus Lilie. Stay on this wide path, which allows you to discover some superb tree specimens, ignoring a shortcut on the right about 300 m further on, near a bench. In a wide curve to the right after a sequoia and a giant thuja, find an intersection.
Turn right and head downhill towards Gasthaus Lilie. Enjoy the explanations about this arboretum (in German, English and French) along the way. Pass a children's playground and then the inn and reach the Liliental car park (S/E).
