Via Sancti Martini HW-35-12b Weil der Stadt - Leonberg

The Via Sancti Martini HW-35-12b is a 21-km point-to-point trail in Baden-Württemberg, Germany, gaining 177 m of elevation on a single day's walk. Rated easy-to-moderate, this stage of the International Walking Network pilgrimage links the medieval market town of Weil der Stadt — birthplace of astronomer Johannes Kepler — with the hilltop town of Leonberg through the rolling Heckengäu hedgerow landscape.

About the Via Sancti Martini HW-35-12b Weil der Stadt – Leonberg

The Via Sancti Martini — named for Saint Martin of Tours (316–397 AD), the Roman soldier-turned-bishop famous for sharing his cloak with a beggar in Amiens — is one of Europe's defining spiritual walking routes. Stretching from Szombathely in Hungary, where Martin was born, to his tomb in Tours, France, the full Via Sancti Martini spans more than 2,300 km across eight countries. In Germany, the route is divided into regional Hauptwege (main paths) and Nebenwege (branch paths), all coordinated by the Martinuswege network, operated in Baden-Württemberg by the Diözese Rottenburg-Stuttgart.

HW-35-12b is a sub-stage of Hauptweg 35, the Stuttgart-region section that carries the pilgrimage route between the Schwäbische Alb foothills and the Rhine. At 21 km with just 177 m of cumulative elevation gain, it is a comfortable full-day walk accessible to any reasonably fit adult. The terrain crosses the Heckengäu — a protected landscape of dense hedgerows, ancient orchards, and unimproved meadows sitting between Stuttgart's urban fringe and the northern Black Forest foothills — and the route is waymarked throughout with the yellow Martinusweg scallop shell.

What distinguishes this stage from typical day hikes in Baden-Württemberg is its cultural layering. Within 21 km, the trail moves through a Renaissance market square, past a monastery complex, and alongside two centuries-old chapels before arriving at a hilltop town occupied since the early medieval period. For pilgrims walking the full Via Sancti Martini, HW-35-12b connects from the preceding stage at Böblingen and leads into stage HW-35-12c onward toward Stuttgart-Schlossplatz, making it a key link in the trans-European chain.

Route Overview & Stages

The trail runs west to east from Weil der Stadt to Leonberg, covering 21 km across three sub-sections of roughly equal length. Each section has a distinct character: historic townscape, open Heckengäu farmland, and a vineyard-edged approach to Leonberg. Waymarking uses the yellow Martinusweg scallop shell supplemented by local Kreiszeichen (district markers) and is consistent throughout.

Highlights & Points of Interest

• Weil der Stadt Marktplatz — The medieval market square is a well-preserved Renaissance ensemble centred on the Johannes-Kepler-Brunnen fountain, marking the 1571 birthplace of the great astronomer. The adjacent 15th-century Stadtkirche St. Peter und Paul provides the trail's spiritual opening atmosphere and is worth 20 minutes inside before setting off.
• Spitalkapelle — This modest wayside chapel at the edge of the old town was originally attached to a medieval almshouse. It marks the official start of the HW-35-12b waymarked route and carries a pilgrim blessing plaque; pilgrims collecting stamps in a Martinus Pilgerausweis will find their first opportunity here.
• Brenzkirche, Weil der Stadt — A civic church named after the Swabian reformer Johannes Brenz. Its understated Protestant interior makes a counterpoint to the Catholic pilgrimage narrative of the Via Sancti Martini and reflects the religious complexity of this corner of Württemberg during the 16th-century Reformation.
• Naturpark Heckengäu — For much of the route's central section, the trail passes through the protected 460 km² Heckengäu landscape, defined by dense hedgerows (Hecken), centuries-old orchards, and unimproved wildflower meadows. The park supports some of Baden-Württemberg's richest populations of wild orchids, skylarks, and lesser whitethroat warblers.
• Heilig-Kreuz-Kapelle — The wayside Chapel of the Holy Cross, set in open farmland near Merklingen, is a classic Wegkapelle of the type that once marked every major pilgrimage route in southern Germany. Recently restored, it now serves as a mid-route rest point with a pilgrim guestbook and a wooden bench in the shade.
• Renninger See — The wetland area surrounding this small lake on the outskirts of Renningen offers a natural break and birdwatching opportunity mid-route. Grey herons and kingfishers are resident year-round. An optional 2-km loop around the shoreline adds roughly 30 minutes and is well worth the detour in spring.
• Leonberg-Eltingen Historic Quarter — The district of Eltingen, incorporated into Leonberg in 1975, retains its medieval street plan with a concentration of half-timbered Fachwerkhäuser. The 12th-century church tower is visible from the final approach descent and signals the approaching end of the stage.
• Pomeranzengarten, Leonberg — Laid out in 1609 for Duchess Sibylla by ducal court gardeners, the Pomeranzengarten is one of the oldest surviving Renaissance formal gardens in Germany. Admission is free, and the restored orangery and parterre are in excellent condition for a 2026 visit, making it a rewarding final stop before the train home.

Best Time to Hike the Via Sancti Martini HW-35-12b Weil der Stadt – Leonberg

May is the single best month to hike the HW-35-12b. Temperatures in the Heckengäu sit between 12 °C and 18 °C, wildflower meadows are at peak bloom, trail surfaces are firm after spring drainage, and the route is quiet before summer school-holiday crowds. Long daylight past 9 pm removes any time pressure on a 21-km stage.

April is a strong alternative: temperatures are cooler (8–14 °C) and spring blossom on the hedgerows is spectacular, though some mornings start damp after overnight rain. September and October bring the harvest-season character of the Swabian countryside — apple orchards line stretches of the route near Renningen — with comfortable 10–16 °C temperatures and outstanding golden-hour light for photography. As of 2026, trail surfaces through late October remain suitable for trail shoes without waterproofing.

June through August is viable but demands planning for heat. Temperatures can reach 28–32 °C and the central agricultural stretch between Merklingen and Renningen is fully exposed. Starting before 8:30 am and carrying a minimum of 1.5 litres of water from Weil der Stadt is strongly recommended; water sources between the three main towns are limited.

November to March is not recommended for most walkers. Agricultural field tracks can become churned and muddy, exposed hedgerow sections offer little wind protection in winter conditions, and several pilgrim guesthouses along the Martinusweg close from November through March.

Practical Information

Accommodation

HW-35-12b is a single-day stage, so overnight accommodation is only needed at either end. In Weil der Stadt, the Gasthof Zum Löwen on the Marktplatz offers double rooms from €65/night including breakfast; it sits a 3-minute walk from the trailhead. The local Catholic parish coordinates a small pilgrim guesthouse (contact tourist.info@weil-der-stadt.de in advance), with beds from approximately €25/night in shared rooms with linen provided. The town's tourist office at the Rathaus can also assist with last-minute bookings during opening hours.

In Leonberg, the Hotel Goldenes Rössl in the Eltingen quarter offers doubles from €80/night in a building dating to 1720. Budget Pensionen on the ring road start from €55/night. Leonberg lies just 18 km from Stuttgart, so the full range of city hotels is a practical alternative for travellers with flexible plans. For pilgrims walking the full Martinusweg, the official Martinuswege accommodation database lists certified Pilgerherbergen along the entire route, with dormitory beds typically available from €20–35/night.

Getting There & Back

Both trailhead towns are served by S-Bahn line S6 from Stuttgart Hauptbahnhof, making point-to-point logistics simple without a vehicle. The recommended direction is west to east — starting in Weil der Stadt and finishing in Leonberg — which follows the official Via Sancti Martini waymarking direction toward Tours.

• Weil der Stadt: S6 from Stuttgart Hbf, approximately 45 minutes. Trains run every 30 minutes during daytime hours. The trailhead at Marktplatz is a 3-minute walk from Weil der Stadt station.
• Leonberg: S6 to Stuttgart Hbf, approximately 20 minutes. Trains run every 15–20 minutes. The trail terminus near Eltingen is a 10-minute walk from Leonberg station.
• Stuttgart Airport (STR): The nearest international airport. Take S2 or S3 to Stuttgart Hbf (27 minutes), then S6 to Weil der Stadt. Total travel time approximately 1 hour 20 minutes.
• Car access: A free Parkplatz near the Stadtkirche in Weil der Stadt is available for day-hike parking. Take the S6 from Leonberg to collect the car at the end of the day.

All connections operate within the VVS (Verkehrsverbund Stuttgart) regional transit network. As of 2026, a single Zone 3 ticket costs approximately €6.80; a VVS group day ticket for up to 5 people costs €16.50, making group travel a clear saving over individual fares.

Permits & Fees

No permit or trail fee is required. The route follows public footpaths and agricultural tracks throughout Baden-Württemberg, and access is free year-round. There is no mandatory pilgrim credential for walking the Martinusweg, though pilgrims wishing to collect stamps at churches and chapels en route may purchase a Martinus Pilgerausweis from the Martinuswege network for €5 — a personal memento, not a legal requirement. The Pomeranzengarten in Leonberg charges no admission and is open from April to October during daylight hours.

Gear & Packing List

At 21 km with 177 m of elevation gain and no technical terrain, HW-35-12b demands day-hiking kit rather than expedition equipment. Trail surfaces mix compacted forest tracks, sealed farm roads, and cobbled historic streets. The following covers every essential for a comfortable day on this route.

• Footwear: Trail shoes or lightweight hiking boots with a cushioned midsole. The cobbled sections in Weil der Stadt and Leonberg-Eltingen are harder underfoot than the field tracks; cushioning matters more than ankle support on this terrain.
• Backpack: A 20–35-litre pack suits a single-day stage. The Deuter Aircontact Lite 45+10 is well-suited for pilgrims carrying multi-day loads on the full Martinusweg, while day-hikers wanting a lighter option will find the Osprey Aether 65 equally capable for one-day outings. For minimum-weight ambitions, our Best Ultralight Backpacks of 2026 guide lists tested sub-700 g options including the Zpacks Arc Haul Ultra 50L, a standout for carrying a full week's kit at minimal pack weight on extended Martinusweg sections.
• Water: Carry at least 1.5 litres from the start. Potable water is reliably available in Weil der Stadt (Marktplatz fountain), Merklingen, and Renningen. Between these towns there are no guaranteed sources, particularly on the exposed mid-route stretch.
• Food: One day on this trail burns roughly 600–800 kcal at a moderate pace with a light pack. Read our guide on how many calories you need hiking a full day for a personalised estimate based on body weight and load.
• Rain layer and navigation: Even in May and September, afternoon convective storms are possible over the Swabian Hills. A packable waterproof shell under 300 g is adequate. The Martinusweg scallop-shell waymarking is reliable throughout, but downloading the GPX track from OpenStreetMap relation 3734988 as an offline backup is recommended.

Similar Trails You Might Like

If HW-35-12b appeals for its combination of cultural heritage, consistent waymarking, and accessible terrain, the wider network of European long-distance routes in Germany offers natural extensions and contrasts. The Europäischer Fernwanderweg E8 (Rheinland-Pfalz) and E8 (Nordrhein-Westfalen) both cross western Germany as sections of a 4,390-km route connecting the Atlantic to the Black Sea — similar cultural density to the Martinusweg, with river-valley scenery replacing the Heckengäu hedgerows. Farther north, the E11 (Sachsen-Anhalt W), E11 (Sachsen-Anhalt O), and E11 (Brandenburg O) form sections of a 2,070-km route tracing the North German Plain — flatter in profile but rewarding for open landscape and historic Hanseatic towns. For an entirely different register, the Theth to Valbona hike in Albania delivers dramatic mountain scenery in the Albanian Alps with far wilder conditions and minimal infrastructure — a compelling choice for hikers who want to step well beyond the managed European trail network.

Frequently Asked Questions

What is the best time of year to hike the Via Sancti Martini HW-35-12b?

May is the optimal month. Temperatures in the Heckengäu range between 12 °C and 18 °C, wildflower meadows are at peak bloom, and the route is quiet before summer school-holiday crowds arrive. April and September are strong second choices — both offer comfortable temperatures and excellent photographic light. Avoid January to March if possible; agricultural tracks can be muddy and several pilgrim guesthouses along the Martinusweg close over winter.

How difficult is the Via Sancti Martini HW-35-12b?

The trail is rated easy-to-moderate. The 21-km distance is achievable for any reasonably fit adult with basic trail-walking experience, and the 177 m of cumulative elevation gain is spread evenly across the route with no sustained climbs. The main challenge on a summer day is the exposed agricultural terrain mid-route between Merklingen and Renningen, where shade and water sources are limited. Trail shoes rather than heavy boots are entirely sufficient.

How long does it take to walk the Via Sancti Martini HW-35-12b?

The trail covers 21 km from Weil der Stadt to Leonberg. At a comfortable 4 km/h walking pace including short breaks at the Spitalkapelle, Heilig-Kreuz-Kapelle, and Renningen, the route takes 5 to 6 hours. Pilgrims stopping at multiple churches, exploring the Pomeranzengarten, or adding the Renninger See shoreline loop should allow a full 7 hours. The stage is designed as a single full day's walk.

Where can I stay near the Via Sancti Martini HW-35-12b?

Overnight accommodation is available at both ends of the stage. In Weil der Stadt, the Gasthof Zum Löwen (doubles from €65) and a parish pilgrim guesthouse (from €25/night) serve walkers. In Leonberg, the Hotel Goldenes Rössl (doubles from €80) and several Pensionen offer budget options from €55. Full-route pilgrims should consult the certified Pilgerherbergen listed on the official Martinuswege website, where dormitory beds run €20–35/night.

Do I need a permit to hike the Via Sancti Martini HW-35-12b?

No permit is required. The trail follows public rights of way throughout Baden-Württemberg, and there is no entry fee for any section of the route. The Pomeranzengarten in Leonberg, near the trail's end, is also free. Pilgrims may optionally purchase a Martinus Pilgerausweis for €5 to collect stamps at churches and chapels along the way, but this is a personal keepsake — not a legal requirement for walking the trail.
