The GR20 is renowned for being one of the most challenging long-distance hiking trails in Europe. Located in Corsica, this trek tests even seasoned hikers with its rugged terrain, steep ascents, and unpredictable weather conditions. Understanding what makes the GR20 so difficult can help you prepare adequately for this adventure.
What Makes the GR20 So Difficult?
The GR20’s difficulty stems from several factors, including its demanding physical challenges and the mental resilience required to complete it. Here’s a closer look at the main reasons:
1. Rugged Terrain and Elevation Changes
The GR20 spans approximately 180 kilometers across Corsica’s mountainous landscape. The trail features:
- Steep ascents and descents, often requiring scrambling over rocks
- Narrow paths alongside precipitous drops
- Rough, uneven surfaces that demand constant attention
Hikers face significant elevation changes daily, with the trail’s highest point reaching over 2,000 meters. This elevation adds to the physical strain and increases the risk of altitude-related challenges.
2. Unpredictable Weather Conditions
Corsica’s weather can be surprisingly variable, especially in the mountains. Hikers must be prepared for:
- Sudden storms that can make paths slippery and dangerous
- High winds that challenge balance and stability
- Temperature fluctuations from hot days to chilly nights
These conditions require hikers to pack versatile gear, including waterproof clothing and layers to adjust to changing temperatures.
3. Limited Accessibility and Resources
Unlike many popular hiking destinations, the GR20 offers limited access to supplies and amenities:
- Few resupply points, requiring careful planning for food and water
- Basic refuges with minimal comforts — reservations are often needed
- Remote locations that make emergency evacuations challenging
Hikers must carry enough provisions between stops, adding to the weight of their packs and the overall difficulty of the trek.
4. Physical and Mental Endurance
Completing the GR20 is as much a mental challenge as it is physical. Hikers need:
- Stamina to endure long days of hiking, often 6-8 hours daily
- Mental resilience to push through fatigue and discomfort
- Navigation skills to stay on track, particularly in foggy or poorly marked areas
The trail’s demands require thorough preparation and a strong commitment to see the journey through.
How to Prepare for the GR20
Preparation is key to tackling the GR20 successfully. Here are some tips:
- Train in advance: Build stamina with regular hikes, focusing on elevation gain.
- Pack wisely: Bring essential gear, including a reliable map, compass, and sturdy boots.
- Plan your itinerary: Research refuges and plan your daily stages to match your pace.
- Stay informed: Check weather forecasts and trail conditions regularly.
