Best Hikes in France: From the Alps to the Pyrenees

France is one of Europe's great hiking nations. The country maintains over 180,000 kilometers of marked trails, an extensive network of mountain refuges and gites d'etape (rural hostels), and a hiking culture that runs deep -- the Federation Francaise de la Randonnee Pedestre (FFRandonnee) has been maintaining trails since 1947. From the Mediterranean scrublands of Corsica to the glaciated peaks of the Mont Blanc massif, the diversity of terrain and landscape is extraordinary.

The French trail system is organized around the GR (Grande Randonnee) network, a series of long-distance footpaths marked with red-and-white blazes. These are complemented by GRP (Grande Randonnee de Pays) loops and PR (Promenade et Randonnee) day hikes marked in yellow. The marking system is consistent and reliable, making navigation straightforward even without a GPS device -- though carrying a detailed IGN (Institut Geographique National) map at 1:25,000 scale is always recommended.

Here are five of the best hikes in France, ranging from legendary multi-week traverses to accessible day hikes.

GR20: Corsica's Mountain Spine

The GR20 is widely considered the toughest long-distance trail in Europe, and it is also one of the most spectacular. Running 180 kilometers along the mountainous spine of Corsica from Calenzana in the northwest to Conca in the southeast, it crosses rugged granite landscapes, alpine lakes, and dense forests of Laricio pine. The scenery is wild and dramatic -- Corsica's mountains rise sharply from the Mediterranean, and the views combine rocky peaks with glimpses of the sea far below.

Duration: The full trail takes 15-16 days for fit hikers. Many people hike only the northern half (considered more difficult and scenic) in about 8 days.

Difficulty: Very demanding. The trail involves significant scrambling, steep ascents and descents, and exposure to weather at altitudes up to 2,225 meters (Monte Cinto, Corsica's highest peak, is nearby). Some sections require hands-on rock scrambling and a head for heights.

When to go: June through September. July and August are busiest but offer the most reliable weather. June still has snow on higher passes. September is cooler and less crowded.

Accommodation: Mountain refuges (refuges) are spaced along the route, typically a day's hike apart. Bunks cost around EUR 15-18 per night. Meals are available at most refuges (dinner around EUR 20, breakfast EUR 10). Camping near refuges costs EUR 7-10. Reservations are strongly recommended from June through September via the Parc Naturel Regional de Corse website.

Practical tip: The GR20 is not a hike to attempt without preparation. You need good mountain fitness, proper equipment (including a sleeping bag, waterproofs, and warm layers for altitude), and confidence on exposed terrain. Start training at least three months in advance with loaded pack hikes on hilly terrain.

Tour du Mont Blanc

The Tour du Mont Blanc (TMB) is arguably the most famous multi-day hike in the Alps. This 170-kilometer circuit passes through three countries -- France, Italy, and Switzerland -- while circumnavigating the Mont Blanc massif, Western Europe's highest mountain at 4,808 meters. The trail does not summit Mont Blanc itself (that requires mountaineering skills and a guide), but it passes through some of the most dramatic glacial scenery in the Alps.

Duration: 10-12 days for the complete circuit, though shorter sections can be hiked independently.

Difficulty: Moderate to challenging. The daily elevation gains are significant (often 1,000-1,500 meters of ascent per stage), but the paths are well-maintained and there is no technical scrambling. Good fitness and some multi-day hiking experience are essential.

When to go: Late June through mid-September. The most popular months are July and August, when the trail can be busy -- particularly the sections near Chamonix and Courmayeur.

Accommodation: Mountain refuges and hotels are available at the end of each stage. Refuge bunks cost EUR 30-55 per night depending on the country and refuge, with half-board (dinner, bed, and breakfast) typically EUR 55-80. Booking in advance is essential for July and August.

Practical tip: Start and finish in Chamonix or Les Houches (France) for the easiest logistics. The French section of the trail between Les Houches and Les Chapieux passes through the stunning Contamines-Montjoie valley, and the crossing into Italy via the Col de la Seigne is one of the trail's highlights. Consider hiring a luggage transfer service (from EUR 15-20 per bag per stage) if you prefer to hike with a lighter pack.

Verdon Gorge: Europe's Grand Canyon

The Gorges du Verdon in Provence is the deepest canyon in France (and often called Europe's Grand Canyon), with turquoise waters flowing 700 meters below limestone cliffs. Several hiking trails explore the gorge, from easy rim walks to challenging descents to the river.

The Sentier Martel is the classic route -- a 15-kilometer trail that descends into the gorge and follows the river before climbing back to the rim. Named after the speleologist who first explored the canyon in 1905, it involves metal ladders, tunnels (bring a headlamp), and some exposed sections with fixed cables.

Duration: 6-8 hours for the Sentier Martel.

Difficulty: Moderate to challenging. The trail involves significant descent and ascent (around 800 meters of elevation change), metal ladders, and one long tunnel. Not suitable for those with vertigo. Good footwear is essential -- the limestone is slippery when wet.

When to go: April through October. Summer is hot in the gorge (temperatures can exceed 35C), so spring and autumn are more comfortable for hiking. The canyon can be closed during heavy rain due to flood risk.

Practical tip: The Sentier Martel is a point-to-point trail, so you need to arrange transport between the start and finish. The easiest solution is to park at the Chalet de la Maline (start point) and take a taxi back from Point Sublime (end point), or vice versa. Arrive early in summer to secure parking. Bring at least 2 liters of water per person -- there is no drinking water along the trail.

The Calanques: Mediterranean Cliffs

The Calanques National Park, stretching along the Mediterranean coast between Marseille and Cassis, offers some of the most visually striking coastal hiking in Europe. The calanques are narrow, steep-walled inlets carved into white limestone cliffs, with crystalline turquoise water below. The contrast of white rock, deep blue sea, and dark green Aleppo pine forest is unforgettable.

The best day hikes:

• Calanque de Sugiton from the Luminy campus in Marseille (1.5 hours each way, moderate). One of the most accessible and beautiful calanques, with swimming possible in calm weather.
• Calanque d'En-Vau from the Col de la Gardiole parking area (2 hours each way, moderate to challenging). Often considered the most spectacular calanque, with a narrow fjord-like inlet and a small pebble beach.
• The full traverse from Marseille to Cassis (20 kilometers, 8-10 hours, challenging). A long but rewarding day walk covering the entire coastline with views of multiple calanques from above.

When to go: September through June. The park restricts or closes many trails from late June through mid-September due to extreme wildfire risk (access depends on daily fire-risk assessments). Spring is the best time -- the wildflowers are in bloom and temperatures are comfortable for hiking.

Practical tip: Check the park's daily access map (available on the Parc National des Calanques website and app) before setting out, as trail closures due to fire risk are common and enforced. Bring sun protection and plenty of water -- shade is limited on the exposed limestone. Swimming in the calanques is one of the great rewards of the hike, so bring a swimsuit and a drybag.

Pyrenees: The Haute Route (HRP)

The Haute Randonnee Pyreneenne (HRP) is a high-level route traversing the Pyrenees from the Atlantic to the Mediterranean, covering roughly 800 kilometers along the French-Spanish border. It is the most demanding of the three trans-Pyrenean routes (the others being the GR10 on the French side and the GR11 on the Spanish side), staying at higher altitudes and crossing more remote terrain.

Duration: 45-50 days for the complete traverse. Most hikers tackle shorter sections, with popular segments including the Cirque de Gavarnie to Luchon section (about 10 days) and the Ariege section around the Carlit massif.

Difficulty: Very demanding. The HRP is not an officially marked trail -- it follows a general route across high passes, many above 2,500 meters, with some sections requiring basic mountaineering skills (glacier travel on the western end, scrambling elsewhere). Navigation skills and mountain experience are essential.

When to go: July through September. Snow can linger on high passes into July.

Shorter alternatives in the Pyrenees: The Cirque de Gavarnie (a UNESCO World Heritage Site) is one of the most impressive natural amphitheaters in Europe, and the hike from the village of Gavarnie to the base of the cirque is an easy and accessible day walk (3-4 hours round trip). The Lac de Gaube near Cauterets is another excellent day hike with views of the Vignemale, the highest peak in the French Pyrenees.

Practical tip: The Pyrenees are quieter than the Alps, with fewer hikers and a more remote, wild character. Accommodation options are more spread out, so be prepared to carry camping equipment on some sections. The French-Spanish border area has limited mobile phone coverage. Always carry a detailed map and consider a personal locator beacon for remote sections.

Essential Gear for Hiking in France

Regardless of the trail, certain equipment is universal for hiking in France:

• Footwear: Sturdy, broken-in hiking boots with ankle support for mountain trails. Trail shoes are fine for coastal and low-altitude hikes.
• Navigation: IGN 1:25,000 maps are the gold standard. Download offline maps on your phone as backup. The IGN Rando app is useful.
• Water: Carry at least 2 liters per person per day. In mountains, streams and springs are generally safe (but treat water from sources near livestock). In Mediterranean areas, water sources are scarce.
• Sun protection: The sun at altitude and on the coast is intense. High-SPF sunscreen, sunglasses, and a hat are essential.
• Layers: Mountain weather changes rapidly. Even in summer, carry a warm fleece or insulated layer and a waterproof jacket for any hike above 1,500 meters.

France's hiking trails offer something for every level of ambition and fitness. Whether you have an afternoon to explore the Calanques or six weeks to cross the Pyrenees, the trails are waiting.
