The Stevenson Trail (GR70) is a legendary 270km thru-hike through the Cévennes, following the route described in 'Travels with a Donkey'.
Hikers traverse the dramatic granite landscape of Mont Lozère (1,699m) and descend into the deep, chestnut-filled valleys of the southern Massif Central.
The trail is famous for its cultural depth, passing through historic villages like Pont-de-Montvert and Florac in the heart of the Tarn Gorge region.
Technically accessible as a Class 1 walking trail, the challenge lies in the sustained 12-day distance and the variable weather of the mid-altitude plateaus.
Many travelers still hire donkeys from local farms, replicating the authentic experience of the 19th-century journey from Le Puy-en-Velay toward the Gard.
Overview
Technical Summary
The GR70, universally known as the Stevenson Trail, traces the historic 1878 journey of Scottish author Robert Louis Stevenson and his donkey, Modestine. This 270km linear hike begins in the volcanic hills of the Haute-Loire, crosses the granite plateau of Mont Lozère, and descends through the forested valleys of the Cévennes National Park to finish in the Gard.
Walking in the Footsteps of History. The 'X-Factor' is the literary romance. Re-reading Stevenson's classic book, *Travels with a Donkey in the Cévennes*, while physically walking through the exact tiny hamlets and sleeping in the same chestnut woodlands he described over a century ago adds a powerful, romantic narrative layer to the physical hike. Many hikers still choose to hire a local pack donkey to replicate the experience.
Hazard Assessment
As the trail moves south into the deeper valleys of the Cévennes (Lozère to Gard), the climate shifts from temperate to distinctly Mediterranean. The deep, rocky gorges trap intense, suffocating heat in July and August.
The crossing of Mont Lozère (the highest point at 1,699m) is entirely exposed. Sudden, sustained storms or dense freezing fog can hit the barren granite summit plateau unexpectedly.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.
Stage Breakdowns
Le Monastier to Le Bouchet-Saint-Nicolas
Starting in the Velay region, walking through volcanic landscapes and peaceful agricultural plateaus.
Le Bleymard over Mont Lozère
The highest point of the trek. Crossing the barren granite summit of Mont Lozère (1,699m) before descending to Pont-de-Montvert.
Pont-de-Montvert to Florac
Following the Tarn valley through the heart of the Cévennes, entering the chestnut forests and historic Camisard country.
Florac to Saint-Jean-du-Gard
Trailing south through increasingly Mediterranean landscapes, ending in the historic silk-town of Saint-Jean-du-Gard.

Technical Profile
Vertical Ascent Profile
A long, rolling traverse that slowly descends towards the Mediterranean. The trail climbs gently over volcanic hills, hits its massive peak crossing the bare granite of Mont Lozère, and then plunges rapidly down steep, rocky zig-zags deep into the heavily crinkled, forested valleys of the Cévennes.
Terrain Characteristics
Trekking (Class 1) — well-marked trail walking through varied terrain with no technical scrambling or specialized skills required.
The cumulative energy expenditure for The Stevenson Trail (GR70) represents a significant physical commitment. Success requires adequate preparation and moisture management.

Risk Summary
Professional evaluation of route mechanics and environmental stress factors. Recommended for participants within specified technical scope.
This profile uses the HikeMetrics v1.0 risk matrix, prioritizing environmental stress and movement complexity over simple elevation metrics.
Technical Specs
Access & Logistics
Regulations
No permits. Inside the National Park core zones (like Mont Lozère), strict bivouac rules apply (tents allowed within 50m of the GR path, between 7 PM and 9 AM only).
Seasonality
May, June, and September are ideal. July and August can be very hot in the southern Gard section. Mont Lozère crossings should be avoided during heavy winter snow without experience.
