Hiking the Corsica GR20
Taking on this incredible journey is no small task, but thousands of people embark on it every year, and with the right preparation and information, you can too. Here's what you need to know if you're considering hiking the GR20.
GR20 - Route
You have two options for walking the GR20: from north to south or from south to north. Which one's better? Well, it depends on how fit you are and what kind of experience you're after.
Traditionally, people start from the north and end in the south. But since most hikers go southward, some suggest starting from the south and going north instead.
The GR20 can be split into two parts. The northern part, from Calenzana to Vizzavona, is the toughest with its steep and rocky paths, but it's also the most stunning. The southern part, from Vizzavona to Conca (or the other way around), is easier, though less impressive overall. Still, the Coscione plateau with its green meadows is absolutely beautiful.

GR20 - How many days?
Although seasoned hikers can manage to complete the trail in just under seven days, the standard time to hike the full GR20 trail is about two weeks. However, the duration of the long-distance walk heavily depends on your fitness level and objectives.
GR20 - Distance
The full GR20 route is approximately 180 kilometers long (112 miles) if you stick to the traditional path without taking any alternatives. However, many trekkers choose to take several alternate routes, which can either lengthen or shorten the total distance, depending on the routes chosen.
GR20 - Elevation Profile
Over the entire 113-mile journey, the GR20 boasts a staggering 34,500 feet or 10,500 meters of elevation change! Spread across 16 stages, this means tackling over 2,150 feet or 655 meters of elevation change per day. However, many trekkers choose to complete the GR20 in fewer days, intensifying the challenge even further!

GR20 - Difficulty
The GR20 is widely renowned for its difficulty. This hike shouldn't be underestimated, as it poses a significant physical challenge, especially when you're carrying a heavy backpack. To embark on this journey, you need to be in good shape, fairly experienced, but above all, you must be genuinely motivated. We strongly advise having some mountain-walking experience beforehand.
GR20 - Deaths
The notoriously challenging section of the GR20 known as the Circ de Solitude has been closed since 2015 following a tragic incident where a small avalanche claimed several lives. While this closure has increased the total distance of the trek by around 15 kilometers, it has significantly reduced the risk of fatalities. However, on average, six people still lose their lives on this trek each year due to various factors such as heart attacks, falls, and exposure.
