Via Sancti Martini HW-35-12c Leonberg - Stuttgart/Schlossplatz

The Via Sancti Martini HW-35-12c is a 23 km point-to-point trail in Baden-Württemberg, Germany, gaining approximately 350 m of elevation as it follows the Martinusweg pilgrimage route from the Renaissance town of Leonberg to Stuttgart's baroque Schlossplatz. Rated moderate, it crosses heathland reserves, a royal palace ridge, and Stuttgart's highest peak before descending into Germany's sixth-largest city.

About the Via Sancti Martini HW-35-12c Leonberg – Stuttgart/Schlossplatz

The Via Sancti Martini — Martinusweg in German — is one of Europe's great pilgrimage corridors, spanning roughly 2,600 km from Szombathely in Hungary, the birthplace of Saint Martin of Tours, to Tours in France, where the bishop and patron of soldiers died in 397 AD. Designated as an International Walking Network (IWN) route, it passes through Austria, Germany, Luxembourg, and Belgium, weaving together ancient monastic roads, Roman highways, and medieval market tracks.

The HW-35-12c segment covers the 23 km between Leonberg and Stuttgart/Schlossplatz, forming the approach into one of Germany's most important industrial and cultural cities from the west. The "c" designation marks this as a variant of the primary HW-35-12 corridor, routed specifically to take pilgrims through the Gerlinger Heide, the ridge estate of Schloss Solitude, and the Birkenkopf — Stuttgart's highest point at 511 m, a hill shaped from over a million cubic metres of wartime rubble — before descending into the city's vineyard-ringed basin.

The Diocese of Rottenburg-Stuttgart manages this section and maintains waymarking with the distinctive Martinusweg cloak-and-shell symbol. The trail runs entirely on public footpaths, a mix of surfaced tracks and natural forest trails, and despite passing through one of Europe's most densely populated regions, more than half the route crosses protected green space. Stuttgart's Kessellage geography — the city sits in a warm basin surrounded by forested hills — means walkers descend into a pocket of warm, wine-growing microclimate unique in central Germany.

This route suits confident day-walkers, pilgrims walking the wider Via Sancti Martini, and anyone wishing to approach Stuttgart on foot following the historical path of medieval wanderers. In character it differs substantially from mountain routes like the Theth to Valbona hike in Albania: the Martinusweg is an urban-fringe walk rich in cultural depth rather than alpine drama, and its accessibility by public transport from Stuttgart makes it unusually easy to plan as a one-way day trip.

Route Overview & Stages

The 23 km unfolds across four natural walking segments. Cumulative elevation gain is approximately 350 m; the route finishes around 200 m lower than it begins, as Leonberg (c. 450 m) sits on the Swabian uplands above Stuttgart's valley floor (c. 245 m at Schlossplatz). The main ascent comes in Stages 2 and 3 as the path rises onto the Solitude ridge before the long urban descent.

Highlights & Points of Interest

• Leonberg Pomeranzengarten — A rare surviving baroque citrus garden established under Duke Friedrich I of Württemberg around 1609, laid out adjacent to the ducal palace at the town's western edge. The restored terraced garden is unique in Germany for its historical continuity and provides a symbolic and photogenic departure point at the trail's start.
• Leonberg Marktplatz — The compact medieval market square is framed by half-timbered buildings and the 15th-century Stadtkirche, set beneath the hilltop castle precinct. The market town's long connection to the St. Martin pilgrimage tradition makes it a fitting opening to HW-35-12c.
• Gerlinger Heide — A protected heathland plateau between Gerlingen and the Solitude ridge, offering unobstructed views across the Strohgäu plains to the Black Forest on clear days. The heath supports rare early-purple orchid species in May and represents one of the last large open heathlands within greater Stuttgart's municipal boundary.
• Schloss Solitude — An 18th-century rococo palace built for Duke Carl Eugen of Württemberg between 1763 and 1769, perched on a ridge at approximately 490 m with sweeping views over the Stuttgart basin. Entry to the courtyard and surrounding parkland is free; interior guided tours run seasonally for approximately €5 per adult.
• Birkenkopf (Monte Scherbelino) — Stuttgart's highest point at 511 m is an artificial hill formed from the rubble of bombed-out city buildings cleared after World War II bombing raids. A stone memorial at the summit marks the names of destroyed streets. The panorama from the top stretches across the entire Stuttgart basin and, on clear autumn days, reaches the Swabian Alb 50 km to the south-east.
• Bärenschlössle — A historic hunting lodge estate set within mature beech and oak woodland in the river valley west of Stuttgart's city centre. The trail descends through this forested area on its approach to the urban stretch, and the shaded footpaths offer a quiet green corridor before the city begins in earnest.
• Karlshöhe — A vineyard-topped hill with a terrace viewpoint over the Stuttgart valley, the Neckar river, and the Cannstatter Wasen fairground site. The terrace has functioned as a city promenade since the early 19th century and marks the final elevated point before the descent to Schlossplatz.
• Stuttgart Schlossplatz — The baroque Neues Schloss borders this 50,000 m² central square, the formal endpoint of HW-35-12c. The adjacent Altes Schloss and the Stiftskirche complete one of southern Germany's finest historic urban ensembles. The nearest U-Bahn stop, Stadtmitte, is approximately 400 m from the square's southern edge.

Best Time to Hike the Via Sancti Martini HW-35-12c Leonberg – Stuttgart/Schlossplatz

The HW-35-12c is walkable year-round, but the experience changes sharply by season. Stuttgart's basin climate makes the city one of Germany's warmest urban areas, though the ridge sections around Solitude and Birkenkopf sit noticeably cooler and more exposed than the valley below.

Spring (April–May) brings wildflower bloom across the Gerlinger Heide, with early-purple orchid species peaking in May, and beech forest in fresh leaf by late April. Temperatures on the ridge range from 12–18°C; in Stuttgart's basin, 15–22°C is typical. Paths are firm and dry from mid-April onward once winter moisture has drained from the clay-heavy soils of the Strohgäu.

Summer (June–August) sees full sun and temperatures that regularly exceed 30°C in Stuttgart's bowl in July and August. The exposed stretch between Gerlingen and Schloss Solitude has minimal shade — carry at least 2 litres of water from the start, with the option to refill at the Schloss Solitude café, which is open seasonally. Evening light on the Karlshöhe vines in late June is exceptional.

Autumn (September–October) is the single best period. As of 2026, September is the recommended month for this trail. Grape harvest runs through Stuttgart's surrounding vineyards from mid-September; temperatures of 18–24°C are reliable; autumn colour on the Birkenkopf and Bärenschlössle forest is outstanding; and trail traffic is noticeably lighter than peak summer. October remains pleasant but rainfall increases toward the end of the month.

Winter (November–March) brings short days, muddy forest paths, and occasional snow on the Solitude ridge. The route remains passable for experienced walkers, but Schloss Solitude closes its interior and paths through the Gerlinger Heide can become waterlogged after heavy rain. Not recommended as a first walk on this section.

The single best month is September.

Practical Information

Accommodation

Because HW-35-12c connects two cities served directly by Stuttgart's S-Bahn network, most walkers complete it as a single day trip with no overnight stay required. Pilgrims walking the full Via Sancti Martini corridor typically stay at either end of this segment.

Leonberg: The old town has several guesthouses within 500 m of the Marktplatz start, with double rooms from €65–90/night at traditional Gasthof-style properties. The official Martinusweg website maintains a pilgrim accommodation list (Gastbetriebe) for the Diocese of Rottenburg-Stuttgart, including Leonberg listings with verified pilgrim-friendly rates.

Stuttgart: Options range from the DJH Youth Hostel Stuttgart at Haussmannstraße 27 (approximately €30–40/night per person in a dorm, about 1.5 km from Schlossplatz) to three-star city hotels from €70–110/night. The hostel is particularly convenient for pilgrims arriving late after a long walk.

Along the route: There are no trail huts or pilgrim refuges on this urban-fringe section. Gerlingen has a supermarket and café for mid-morning resupply, approximately 5 km into the walk. The Schloss Solitude café, at the halfway point, is open from May through October.

Getting There & Back

Public transport connectivity on this trail is exceptional — a key advantage for walkers who want a clean point-to-point route without car logistics.

To the start (Leonberg): Take S-Bahn line S6 from Stuttgart Hauptbahnhof (Hbf) to Leonberg; journey time approximately 25 minutes, departures every 20 minutes throughout the day. From Stuttgart Airport (STR), take S-Bahn S2 or S3 to Stuttgart Hbf (27 min), then transfer to S6. Full timetables and the VVS day ticket (covering the entire walk area) are available on the VVS journey planner.

From the finish (Stuttgart/Schlossplatz): Stuttgart Stadtmitte U-Bahn station is 400 m from the Schlossplatz endpoint. Stuttgart Hauptbahnhof is 700 m on foot. ICE trains connect Stuttgart to Frankfurt in 1 hour 10 minutes, and to Munich in 2 hours 10 minutes, making this route easily combined with a wider German touring itinerary.

By car: Driving to either end is not recommended. Parking at Leonberg Marktplatz is limited to short stays. A park-and-ride (P+R) facility at Leonberg Bahnhof offers free parking with a valid VVS day ticket, allowing walkers to drive to Leonberg and return by S-Bahn from Stuttgart.

Permits & Fees

No permits are required and there is no trail access fee. All 23 km run on public rights of way and publicly accessible parks. The only optional costs are Schloss Solitude's guided interior tour (approximately €5/adult as of 2026) and Leonberg's Pomeranzengarten, which charges seasonal admission — check locally for current rates. The Birkenkopf summit and all forest sections are free and open at all times.

Gear & Packing List

HW-35-12c is a one-day walk on mostly well-maintained trails. A lightweight day pack in the 30–40 litre range is sufficient, and since the route ends in Stuttgart's city centre, a bag that functions in an urban environment as well as on the trail is a practical advantage.

Trail runners or light hiking shoes handle the mix of compacted forest path and gravel track well. For summer walks, sun protection and at least 2 litres of water are essential on the exposed Gerlinger Heide section between Gerlingen and Schloss Solitude, where shade is minimal. If you are walking the wider Via Sancti Martini across consecutive days and need a pack that handles both day stages and overnight kit, the 2026 roundup of the best ultralight backpacks covers tested options across exactly this kind of mixed urban-trail pilgrimage context.

Recommended packs for this trail:

• Fjällräven Abisko Hike 35 — a 35 L pack with excellent weather resistance and comfortable carry for a full day on varied terrain; a natural fit for the Martinusweg aesthetic
• Deuter Aircontact Lite 45+10 — ideal for pilgrims walking multiple consecutive stages with overnight kit, offering back ventilation suited to warm summer days on the Solitude ridge
• Osprey Aether 65 — the choice for walkers tackling the full Via Sancti Martini across multiple countries with a complete camping or hostel load

Food planning matters even on a single-day walk of this distance. Read the guide on how many calories you need on a full hiking day before setting out — the 6.5 km final descent from Birkenkopf into Stuttgart is deceptively energy-draining after a long morning on the ridge.

Similar Trails You Might Like

The Via Sancti Martini sits within Europe's broader network of long-distance IWN walking routes. Germany's Europäischer Fernwanderweg trails offer similar multi-day scope with very different landscapes: the E8 crosses Rhine-Moselle wine country heading east across Germany, while the E11 threads through the forests and river plains of central and eastern Germany, where the post-reunification landscape makes for a historically rich experience. For something dramatically different in terrain, the Theth to Valbona trail in Albania trades pilgrimage footpaths for high alpine drama across the Accursed Mountains.

Frequently Asked Questions

When is the best time to walk the Via Sancti Martini HW-35-12c Leonberg – Stuttgart/Schlossplatz?

September is the best month. Temperatures average 18–24°C, Stuttgart's surrounding vineyards are in grape harvest, and autumn colour on the Birkenkopf and Bärenschlössle forest sections is at its peak. Spring (April–May) is a strong second choice for orchid bloom on the Gerlinger Heide. Avoid July–August if heat is a concern, as Stuttgart's basin climate regularly pushes temperatures above 32°C.

How difficult is the HW-35-12c trail?

The route is rated moderate. The 23 km distance with approximately 350 m of cumulative elevation gain is within reach of any fit walker. The main challenge is distance rather than gradient: the climb to Schloss Solitude is gradual, and the descent into Stuttgart is long but never technical. Good footwear and an early 08:00 start from Leonberg leaves comfortable time to finish before dark in all seasons.

How far should I expect to walk each day?

Most walkers complete the full 23 km as a single day, taking 5.5–7 hours at a comfortable pace with rest stops at Schloss Solitude and Birkenkopf. If you are walking the wider Via Sancti Martini across multiple days, typical German sections of the route range from 18–28 km per stage, placing HW-35-12c at the lower-moderate end of a standard pilgrimage day.

Is there accommodation available along the route?

There are no trail huts or pilgrim refuges on this urban-fringe section. Gerlingen (5 km in) has a supermarket and café for resupply, and the Schloss Solitude café is open in summer. For overnight stays, Leonberg has guesthouses from €65–90/night and Stuttgart offers everything from the DJH youth hostel (from €30/night per person) to city hotels from €70–110/night. The official Martinusweg website lists approved pilgrim accommodation.

Do I need a permit or pay any fee to walk this trail?

No permit is required and there is no trail access fee. All 23 km run on public rights of way and publicly accessible parks.
