The GR20: myth, reality, and my take on it

Summary: The GR20 is one of Europe's most famous long-distance hikes and has achieved almost mythical status. It's a rugged, gruelling trek across the mountains of Corsica. Impressive, without a doubt. But let me be honest: it's not the way I would choose to discover Corsica. And that's worth saying.
The GR20 runs from north to south across Corsica, following the island's highest mountain ridges, right through the Parc Naturel Regional de Corse. For many hikers it sits high on their bucket list. The route is known for being technical, physically demanding, and unforgiving. Steep rocks, loose stones, major elevation changes, and long days are all part of the deal.
Anyone who completes the GR20 deserves respect. It's not a walk — it's a serious mountain expedition.
But however impressive it may be, the GR20 isn't necessarily the best way to get to know Corsica.
The appeal of the GR20
The appeal is understandable. The GR20 offers:
- Spectacular views
- A sense of adventure and accomplishment
- Sleeping in mountain refuges high in the peaks
- Days of living with only what you carry on your back
For many people it's about the challenge, the perseverance, and ticking off a legendary route.
Insider tip If you do decide to tackle the GR20, plan realistically. Many hikers underestimate the pace and difficulty of the stages.
The flipside you hear less about
What's less often told is that the GR20 also has its limitations. You follow a fixed line, from hut to hut, often alongside many other hikers. In peak season it can be surprisingly crowded, even in the mountains.
On top of that, you mainly see one side of Corsica: the rugged high mountains. Beautiful, but not the full story.
You miss:
- The coast and the beaches
- The villages and markets
- The peaceful valleys
- The spontaneous stops at beautiful spots
To me, that feels like a missed opportunity.
Insider tip If you're walking in July or August, book refuges well in advance or bring a tent. Full means full, even high in the mountains.
Why I wouldn't do it that way
I love hiking, but I also love freedom. Combining a walk with a long lunch, a dip in a river, or a glass of wine at the end of the day.
The GR20 is intense, structured, and goal-oriented. Every day revolves around the next stage. That suits some people perfectly, but it's not how I prefer to experience Corsica.
Corsica, to me, is:
- A morning walk through a valley
- A mountain path with views, without performance pressure
- An afternoon by the sea
- An evening in a village, with great food
All of that fits poorly into a schedule of hut to hut.
An alternative: Corsica in pieces
Instead of the full GR20, I'd personally choose individual walks spread across the island. That way you taste much more of Corsica's diversity.
Think of:
- A day hike in the Restonica valley
- A mountain trek in the Bavella area
- A coastal walk at Cap Corse
- A forest route in the Balagne
This way you combine mountains, villages, sea, and tranquillity.
Insider tip Want to get a taste of the GR20 anyway? Walk a single stage or a section of it. You'll get the feel of the route without being on the trail for weeks.
Who is the GR20 perfect for?
The GR20 is perfect for those who:
- Are experienced in mountain hiking
- Enjoy a physical challenge
- Like living in basic conditions for days on end
- Focus on achievement and perseverance
For those who want to "experience" Corsica rather than "complete" it, there are other options that are every bit as beautiful.
In brief
- The GR20 is legendary and tough
- It's not the only or best way to discover Corsica
- You mainly see the high mountains, not the whole island
- Individual walks offer more freedom and variety
The GR20 deserves respect. But Corsica also deserves the time, calm, and space to discover the island in your own way.
