200km of clifftop walking along the chalk Alabaster Coast. The Étretat to Fécamp section (24km) is the most dramatic, passing the famous natural arches.
The GR21 is a 200-kilometre long-distance trail (Grande Randonnée) tracing the clifftop of the Côte d'Albâtre — the Alabaster Coast — from Le Havre northward to Le Tréport, passing through Étretat, Fécamp, Saint-Valery-en-Caux, and Dieppe. The Seine-Maritime chalk cliffs that line this coast are among the most dramatic in France, rising to 110 metres above the English Channel before plunging as near-vertical white faces to boulder-strewn beaches. The trail is waymarked in red and white throughout.
The Étretat to Fécamp section — 24 kilometres — is the most celebrated stretch. It begins at Étretat, where the Falaise d'Aval arch and the Porte d'Aval natural window are among France's most photographed natural features. The path climbs immediately from the village to the clifftop and maintains height through the Valleuse d'Antifer before descending to the historic abbey town and industrial port of Fécamp. The walk takes 6–8 hours and involves approximately 600 metres of total ascent and descent, crossing several valleuses — dry chalk valleys cutting perpendicular to the coast. Navigation is straightforward, but cliff-edge proximity demands care, especially in wind or wet weather when chalk surfaces become slippery.
The full GR21 is typically walked as a 10- to 12-day stage hike. Accommodation concentrates in the larger towns; smaller sections between population centres require careful planning. Wild camping is not officially permitted on the clifftops, but several recognised camping grounds exist. The trail is free to walk and requires no permit. Guidebooks covering the GR21 are published by the Fédération Française de la Randonnée Pédestre (FFR) and available from the Étretat tourist office.
Cliff erosion is an ongoing hazard; the trail is occasionally rerouted around recent falls. Current closures are posted by the local mairie and at Étretat's tourist office. The section north of Dieppe towards Le Tréport through the Pays de Caux cliffs is less visited and offers considerable solitude with equally striking scenery. April through October provides the best walking conditions; winter brings short days and more frequent cliff-edge winds.

Tips for visiting
- Walk the Étretat to Fécamp section in the early morning to avoid peak visitor crowds at the arches
- Wear trail shoes rather than heavy boots — the chalk and grass surface is not technical but becomes slippery after rain
- Carry at least 2 litres of water; the clifftop section has no reliable resupply points for 20+ km
- Book accommodation in Fécamp at least 48 hours ahead during July–August when the town fills with visitors
- Trekking poles reduce knee stress significantly on the steep valleuse descents with a loaded pack
Frequently asked questions
Is the GR21 suitable for novice hikers?
The trail requires basic hill-walking fitness but no technical skills. The Étretat–Fécamp day is a serious 6–8 hour walk and should not be underestimated. Shorter section walks from clifftop car parks are available for casual walkers who prefer a half-day outing.
What are the main safety hazards on the trail?
Cliff-edge proximity is the primary risk, especially in strong wind or wet conditions when chalk becomes slippery. Chalk erosion is active along this coast; posted closure notices must be respected and walkers should stay well back from unfenced edges.
Are dogs permitted on the GR21?
Dogs are allowed on the trail but should be kept on a lead near cliff edges. Some accommodation along the route does not accept pets; it is worth checking policies in advance when booking overnight stops.
Is there an entry charge to access the Étretat clifftop viewpoints?
A private operator has purchased land above Étretat's Falaise d'Aval and charges a small fee to use the maintained viewpoint path. The GR21 itself remains a public right of way, but the main arched viewpoint area applies a ticketed access charge.
