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

The Via Sancti Martini HW-35-10b is a 29-km point-to-point pilgrimage trail in Baden-Württemberg, Germany, gaining approximately 452 m of elevation across a walking day of 7–9 hours. With no technical terrain, it suits any fit adult and follows the International Walking Network's Via Sancti Martini from the cathedral city of Rottenburg am Neckar to the medieval market town of Herrenberg across rolling Swabian farmland and quiet village chapels.

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

The Via Sancti Martini is one of the world's great pilgrimage routes, tracing the path of Saint Martin of Tours from his birthplace in Szombathely, Hungary, westward across Europe to his burial site at the Basilica of Saint Martin in Tours, France — a corridor of over 2,300 km. The German section, the Martinusweg, is administered by the Diözese Rottenburg-Stuttgart and threads through some of Baden-Württemberg's most quietly evocative landscapes: the Neckar valley, the Swabian Gäu plateau, and a succession of small market towns whose churches have welcomed pilgrims since the early Middle Ages.

HW-35-10b is the designated main route (Hauptweg) between Rottenburg am Neckar and Herrenberg, covering 29 km and ascending roughly 452 m in total. The route begins at Rottenburg's Dom — a cathedral dedicated to Saint Martin himself that has drawn pilgrims since the 9th century — and winds north-east through the undulating Gäu plateau, a mosaic of arable fields, hay meadows, fruit orchards and traditional Swabian farmsteads, before descending into Herrenberg's old town beneath the late-Gothic towers of the Stiftskirche.

What distinguishes this stage from generic long-distance walking is its layered history. Saint Martin served as a Roman soldier before becoming Bishop of Tours in 371 AD; the route through southwest Germany was travelled by medieval pilgrims for centuries, and the Martinusweg revival in the 21st century has restored waymarkers, re-opened pilgrim hostels, and commissioned a dedicated multimedia audio guide that brings each landscape's stories to life at over 70 waypoints. The trail is signed throughout with the distinctive white Martin cross on a green background, making navigation straightforward even without GPS.

At 29 km, HW-35-10b is a long day for most walkers. Physically capable hikers complete it in 7–9 hours; pilgrims choosing a slower, more contemplative pace often split it overnight at Frommenhausen (roughly 8 km in), where a dedicated pilgrim hostel offers simple, affordable shelter. If you're planning a multi-day food strategy, see our guide on how many calories you need hiking a full day — particularly relevant given the sustained distance across this stage.

Route Overview & Stages

The route runs roughly north from Rottenburg am Neckar across the Gäu plateau and arrives in Herrenberg. Elevation gain is distributed evenly across all three segments, with no single punishing climb — instead, expect a series of modest ascents and descents typical of the Swabian uplands. The plateau sections between Frommenhausen and Bondorf are the most exposed, offering wide agricultural views but little shade in summer.

Total: 29 km | Elevation gain: ~452 m | Estimated walking time: 7–9 hours

Highlights & Points of Interest

• Rottenburg am Neckar Dom (St. Martin's Cathedral) — The traditional starting point of this stage. The cathedral, dedicated to Saint Martin himself, dates to the 9th century in foundation and contains significant Romanesque and Gothic elements. A short blessing service for departing pilgrims is held most mornings; check with the Pilgerstelle on arrival for the current schedule.
• Wallfahrtskirche Weggental — Around 2 km from Rottenburg, this Marian pilgrimage church sits in a sheltered valley where the footpath descends from the Dom along the Unteren Talweg. The baroque interior, with its richly carved altars, offers a natural first rest point and a quiet moment of reflection before the open plateau ahead.
• Reiterhof Eratskirch — A working equestrian farm the route skirts on the way north from Frommenhausen. The surrounding pastures are often occupied by horses and provide a pleasant pastoral contrast to the forested sections either side of the farm.
• Heuberger Höfen — A cluster of traditional Swabian farmsteads perched at one of the higher points on the plateau, reached by a meadow path ascending from the Kreisstraße. Views across the Gäu open up noticeably here, with the Black Forest ridgeline visible to the west on clear days.
• Wendelsheim — A compact Swabian village with a chapel dedicated to Saint Wendelin, patron of shepherds and farmers. The waymarking through the village is especially well maintained; look for the green-and-white Martin cross on gatepost stones dating to the route's early-2000s restoration.
• Bondorf Marktplatz — The route passes through Bondorf's small market square, where a fountain and several Gasthäuser offer the last reliable lunch stop before the final 12 km push to Herrenberg. Stock up on water here if temperatures exceed 22 °C; the next reliable source is Herrenberg itself.
• Herrenberg Stiftskirche — The dramatic late-Gothic collegiate church crowning Herrenberg's old town serves as the visual finish line of this stage. Construction began in 1293; the tower and nave were completed by 1471. The church is dedicated to Saint Mary and Saint Martin — a fitting end to a Martin-themed pilgrim day.
• Johann-Baptist-Hirscher-Haus — Named after the 19th-century theologian born in Herrenberg, this building near the Stiftskirche serves as the diocesan pilgrim contact point for the Martinusweg and provides overnight accommodation for through-walkers arriving in town.

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

The trail is walkable from March through November, but the experience varies considerably by season.

April and May bring fruit blossom to the orchards around Weggental and the hedgerows along the Gäu plateau. Temperatures range from 8–18 °C, rainfall is moderate, and trail surfaces are generally firm by mid-April after winter. This window is popular with pilgrims completing multi-week stages of the full Via Sancti Martini itinerary.

June is the single best month to walk HW-35-10b in 2026. Days are long (sunset after 21:00), wildflower meadows are at their peak along the plateau sections, and average temperatures of 17–22 °C make the 29 km distance comfortable without demanding early starts or large water carries. Accommodation at the Frommenhausen Pilgerherberge is usually available without advance booking during early June.

July and August are manageable but warm — plateau sections offer little shade from 10:00 to 16:00, and temperatures can reach 28–32 °C by mid-afternoon. Start by 07:00 if hiking in summer. Carry at least 2 litres between Frommenhausen and Bondorf, where reliable refill points are sparse.

September and October are excellent, with harvest colours on the farmland, cooler temperatures of 12–20 °C, and reduced pilgrim traffic. Trails dry quickly after rain. The Herrenberg Stiftskirche holds harvest-season services that give arriving pilgrims a memorable welcome at the end of the stage.

Avoid December through February unless experienced in cold-weather walking: the plateau sits above 400 m and can accumulate snow and ice, and several pilgrim accommodations close for the winter months. As of 2026, the Frommenhausen Pilgerherberge is open April 1 to November 15.

From Herrenberg (finish): The S-Bahn S1 runs directly from Herrenberg Bahnhof to Stuttgart Hauptbahnhof in approximately 35 minutes, with trains every 20 minutes throughout the day.

By car: Park at Herrenberg Bahnhof (free on weekends) and take the S-Bahn to Rottenburg to begin the walk, then ride back from Herrenberg. This avoids a vehicle shuttle arrangement and keeps logistics simple.

Permits & Fees

No permits or trail fees are required for HW-35-10b. The route passes entirely through public rights of way and waymarked pilgrimage paths maintained by the Diözese Rottenburg-Stuttgart.

Gear & Packing List

HW-35-10b's 29 km across rolling farmland rewards a lightweight approach.
