Via Sancti Martini HW-35-10a Rottenburg - Herrenberg

The Via Sancti Martini HW-35-10a is a 29-km point-to-point pilgrimage trail in Baden-Württemberg, Germany, gaining 452 m of elevation across pastoral farmland, wooded hillsides and historic market towns. Rated moderate, it traces one classic stage of the Via Sancti Martini — the ancient pilgrim road of Saint Martin of Tours — from the Romanesque cathedral in Rottenburg am Neckar to the medieval Stiftskirche in Herrenberg.

About the Via Sancti Martini HW-35-10a Rottenburg - Herrenberg

The Via Sancti Martini, known in German as the Martinusweg, is one of Europe's major pilgrim corridors, following the historical route of Saint Martin of Tours (316–397 AD) from the Netherlands through France and Germany to Rome. In Baden-Württemberg, the route is stewarded by the Diözese Rottenburg-Stuttgart and carries the official designation of the International Walking Network (IWN), the world's most significant network of long-distance hiking routes.

Stage HW-35-10a connects two of the region's most historically significant towns. The start point, Rottenburg am Neckar, is one of Baden-Württemberg's oldest settlements — a former Roman provincial capital (Roman name: Sumelocenna) — whose Gothic-Romanesque Münster dedicated to Saint Martin forms both the spiritual and geographical heart of the departure. The endpoint, Herrenberg, is a well-preserved medieval market town whose late-Gothic Stiftskirche dates to 1293 and whose compact historic quarter has changed little since the 15th century.

Between the two towns, the 29-km route accumulates 452 m of elevation gain through a varied landscape: first climbing through pilgrimage-church terraces and mixed forest above Rottenburg, then crossing open agricultural ground through the villages of Wendelsheim and Poltringen, then following the HW-35-10a-specific rural track through Altingen before the final descent into Herrenberg. The agricultural mid-section gives the route its pastoral, unhurried character — wide field paths rather than narrow mountain tracks, with long views across the Neckar-Alb district to the Swabian Alps on clear days.

Waymarking is managed by the Diocese and uses Martin-cross discs and scallop shells. The Martinusweg official website provides downloadable GPX tracks, a pilgrim passport application, and stage-by-stage accommodation lists. The HW-35-10a variant is the recommended hiking route between these two towns; the parallel HW-35-10b covers the same distance via more road-adjacent paths better suited to cycling.

The trail fits comfortably into a single long day for experienced hikers — most walkers complete it in 7–9 hours including stops. Alternatively, the stage can be split into two shorter days using accommodation in Wendelsheim or Poltringen at the approximate midway point.

Route Overview & Stages

The HW-35-10a unfolds in four logical sections, each with a distinct character. The first quarter is the most vertical, climbing from the Neckar valley floor to the pilgrimage church terraces above Rottenburg. The central half crosses productive farmland at broadly level elevation. The final section follows the distinctive 10a variant through Altingen before descending into Herrenberg.

Total: 29 km / 452 m elevation gain / 7–9 hours at moderate pace including short breaks.

Highlights & Points of Interest

• Münster St. Martin, Rottenburg am Neckar — The trail's starting point and spiritual anchor. This Gothic-Romanesque cathedral has been dedicated to Saint Martin for over 700 years and houses the primary pilgrim register where walkers collect their first stamp (Stempel) before departure.
• Weggentalkirche (Maria im Weggental) — A Baroque pilgrimage church perched above Rottenburg on a wooded hillside, first documented in the 14th century. The church offers the first elevated viewpoint back over the Neckar valley and the distant silhouette of the Swabian Alb.
• Tannenrain Spring — A natural spring along the Unteren Talweg, approximately 9 km from Rottenburg, provides reliable cold water and a shaded rest spot framed by mature beech and spruce. One of the few reliable water sources on this open stage.
• Reiterhof Eratskirch — A traditional horse farm passed on open meadow tracks east of Rottenburg, marking the visible transition from the town's wooded fringe into the working agricultural landscape of the Neckar-Alb district.
• Heuberger Heights — The highest section of the stage, offering unobstructed views south to the Swabian Alps (Schwäbische Alb) and north across the Neckar valley farmland. On clear days visibility extends more than 50 km.
• Wendelsheim Village — A compact traditional settlement at roughly the midway mark, with a wayside chapel and reliable gastronomy. The natural lunch stop for walkers completing the stage in a single day.
• Altingen (HW-35-10a Specific Routing) — The defining feature of the 10a variant: a quiet village with preserved half-timbered farmsteads and a small historic church that the road-adjacent 10b route bypasses entirely. The path through Altingen feels more rural and pilgrimage-appropriate than the alternative.
• Stiftskirche Herrenberg — The late-Gothic collegiate church dating to 1293 provides a striking visual endpoint, its tower visible from the final descent. Notable for its preserved late-medieval choir stalls and elevated position commanding the old-town roofscape.

Best Time to Hike the Via Sancti Martini HW-35-10a Rottenburg - Herrenberg

The HW-35-10a is walkable year-round, but the experience differs considerably by season. As of 2026, the Martinusweg organisation has confirmed that waymarking across all HW-35 stages has been refreshed following a spring route inspection, with all surfaces in good order.

April–May bring the most photogenic spring conditions: wildflower meadows in the Wendelsheim–Poltringen section, fresh green on the Schönbuch woodland approaches near Herrenberg, and mild temperatures of 12–18 °C. Some agricultural field paths remain soft from winter rainfall into mid-April.

June is the single best month to hike this stage. Ground conditions are dry, daylight extends from approximately 05:00 to 21:30, and temperatures sit in the 20–25 °C range. Accommodation availability is higher than in the peak July–August holiday window, and the exposed Heuberger section is manageable before midday heat builds.

July–August offer maximum daylight but peak temperatures — up to 30 °C on open farm tracks. Start before 07:30 if hiking in midsummer. Pilgrim hostels in Rottenburg and Herrenberg benefit from advance booking during this period.

September–October provide a second excellent window. September brings harvest activity and warm amber light on the vineyard edges near Poltringen. October delivers autumn colour through the woodland approaches to Herrenberg and cooler temperatures of 8–15 °C. The Martinmas feast day on 11 November — dedicated to Saint Martin — draws a modest surge of pilgrims completing final stages before winter.

November–March are passable for experienced hikers but demand appropriate cold-weather preparation. Agricultural tracks can freeze; overnight accommodation reduces significantly; and some churches operate on reduced hours.

Practical Information

Accommodation

The Diocese of Rottenburg-Stuttgart maintains an official network of pilgrim-friendly lodging along the HW-35 corridor. In Rottenburg am Neckar, the Haus Seeger Pilgerherberge offers dormitory beds for approximately €20–28/night, the most affordable option for solo pilgrims. The Johann-Baptist-Hirscher-Haus provides private rooms at around €55–75/night. The guesthouse in Frommenhausen, a short distance outside Rottenburg, is popular as a rest point before or after the stage.

At the Herrenberg end, the KVJS-Tagungszentrum Gültstein offers rooms with pilgrim rates from approximately €60/night. The Naturfreundehaus am Schönbuch provides hostel-style accommodation from €22–35/night. The Tagungsstätte Evangelische Diakonieschwesternschaft accepts pilgrim guests subject to availability. A current, searchable accommodation list with direct contacts is maintained on the official Martinusweg website (martinuswege.de). Book in advance for summer weekends, when all options fill quickly.

Getting There & Back

This stage is exceptionally well-suited to car-free travel. The trailhead in Rottenburg am Neckar is served by regional rail from Tübingen Hauptbahnhof (approximately 20 minutes, RE trains every 30–60 minutes). From Stuttgart Hauptbahnhof the journey is approximately 65–75 minutes with one change at Tübingen. Check current timetables at Deutsche Bahn (bahn.de).

The endpoint in Herrenberg connects directly back to Stuttgart via the S-Bahn S1 line (approximately 35 minutes, frequent service throughout the day). This creates a clean linear day: train from Stuttgart to Rottenburg in the morning, hike 29 km, S-Bahn home from Herrenberg in the evening.

Stuttgart Airport (STR) is approximately 25 km from Herrenberg. Take the S2 or S3 to Stuttgart Hauptbahnhof (~27 minutes) then the S1 to Herrenberg (~35 minutes). International arrivals can reach the Rottenburg trailhead the same day.

Permits & Fees

No permits or trail fees are required. The route follows public rights-of-way maintained by the Diocese of Rottenburg-Stuttgart at no cost. A free Pilgerpass (pilgrim passport) is available at Münster St. Martin in Rottenburg and allows walkers to collect stamps (Stempel) at designated waypoints along the route. Collecting stamps is optional but central to the traditional experience on the Via Sancti Martini. No camping fees apply for the dispersed rest areas on the route.

Gear & Packing List

At 29 km with 452 m of elevation change, the HW-35-10a suits a capable but not heavy setup. Day hikers completing the stage in a single push can travel light with a 35–50 L pack; those splitting it over two days need a volume with meaningful support for overnight gear.

The Deuter Aircontact Lite 45+10 is well-suited to two-day walkers carrying overnight gear, providing excellent back support on the long agricultural track sections. For ultralight multi-stage walkers covering several HW-35 stages back-to-back, the Zpacks Arc Haul Ultra 50L keeps base weight low without sacrificing volume. Those carrying camping equipment would find the Osprey Aether 65 a capable fit, though the well-developed pilgrim hostel network makes camping rarely necessary on this corridor.

• Footwear — Mid-height waterproof hiking boots for spring and autumn; trail runners are adequate on dry summer ground. The agricultural sections between Wendelsheim and Poltringen can be soft after rain.
• Water — Carry at least 1.5 L from Rottenburg. The Tannenrain spring (~9 km) and Wendelsheim (~11 km) offer resupply, but the Heuberger heights stretch has no reliable water for approximately 8 km.
• Navigation — Waymarking is well-maintained but a downloaded GPX backup is recommended. Free GPX files are available from martinuswege.de.
• Sun protection — The central agricultural section is exposed; sunscreen, a hat and sunglasses are essential from June through August.
• Layers — April and October mornings can be 5–8 °C before warming to 18 °C by afternoon; a mid-layer and wind shell are worth carrying.

Frequently Asked Questions

When is the best time to hike the Via Sancti Martini HW-35-10a Rottenburg–Herrenberg?

June is the single best month: ground conditions are dry, daylight runs from 05:00 to 21:30, and temperatures hold in a comfortable 20–25 °C range. April and May are excellent for wildflower meadows and cooler walking conditions. September offers harvest scenery with fewer walkers than midsummer. Avoid December through February unless you have cold-weather hiking experience, as paths can freeze and pilgrim accommodation closes or reduces hours.

How difficult is the HW-35-10a stage?

The route is rated moderate. Distance is the primary challenge rather than technical terrain — paths are well-maintained, fully waymarked, and require no scrambling. The 452 m of elevation gain is spread across the full 29 km, with the steepest section at the Weggentalkirche ascent (approximately 160 m over 4 km). Fit day-hikers with some walking experience will find it achievable; beginners should allow extra time and plan a rest stop in Wendelsheim at the midway point.

How many kilometres per day is realistic on this trail?

The HW-35-10a is a single 29 km stage, normally walked in one day by most pilgrims and hikers. If you prefer shorter daily distances of 15–18 km, an overnight stop in Wendelsheim or Poltringen — roughly at the stage midpoint — turns it into a comfortable two-day walk. Both villages connect to Rottenburg and Herrenberg by regional bus, giving flexibility to adjust plans if conditions change.

What accommodation is available on the route?

Pilgrim hostels (Pilgerherbergen) in Rottenburg charge approximately €20–28/night in dormitory format; private guesthouse rooms run €55–75/night. In Herrenberg, the Naturfreundehaus am Schönbuch offers beds from €22/night and the KVJS-Tagungszentrum Gültstein starts from €60/night. The Diocese maintains a current accommodation list at martinuswege.de. Book in advance for summer weekends, when all options fill quickly.
