The GT20 <\/strong>, also known by its Corsican name A Traversata Mai\u00f2 <\/em>, represents the ultimate cycling adventure in Corsica. This grand crossing of the island connects Bastia to Bonifacio <\/strong>over approximately 600 kilometers of winding roads and breathtaking landscapes. Inaugurated in 2019, this cycle touring route has already established itself as a benchmark for cycling enthusiasts wishing to discover the Isle of Beauty <\/strong>in a different way.<\/p>\n\n\n\n

It’s important to know that the GT20 prioritizes quiet secondary and departmental roads <\/strong>, guaranteeing safety and peace of mind for cyclists. By 2025, this route is attracting more and more cycle tourists thanks to its improved signage and enhanced facilities <\/strong>.<\/p>\n\n\n\n

Furthermore, the option to complete these 12 stages in 6, 8, or 12 days, depending on your fitness level, allows everyone to adapt to their physical abilities <\/strong>and availability. This guide will help you prepare for your trek by detailing the essential stages, the elevation changes to anticipate <\/strong>, camping accommodation options, and tips for efficiently managing your luggage.<\/p>\n\n\n\n

<\/a>Route and stages of the GT20: detailed itinerary of the crossing<\/strong><\/h2>\n\n\n\n
\"The<\/figure><\/div>\n\n\n\n

Organizing your Corsican crossing <\/strong>requires careful planning of the stages and a precise understanding of the route. The GT20 is divided into twelve distinct sections, each revealing unique landscapes between sea and mountains <\/a><\/u><\/strong>.<\/p>\n\n\n\n

<\/a>North to south route: the 12 official stages<\/strong><\/h3>\n\n\n\n

The GT20 route <\/strong>traditionally begins in Bastia and ends in Bonifacio, although the reverse is perfectly feasible. The stages are organized according to a logical structure that respects accommodation availability and reasonable distances for cycle touring <\/strong>.<\/p>\n\n\n\n

The opening stage leads from Bastia to Centuri <\/strong>over 58 kilometers, allowing for a gradual warm-up with the discovery of Cap Corse<\/strong><\/a> <\/a><\/strong>. This first section alternates between moderate climbs and coastal stretches, ideal for acclimatizing to the Corsican terrain. As such, it provides an excellent introduction to the GT20 adventure.<\/p>\n\n\n\n

The route continues from Centuri to Saint-Florent <\/strong>(58 km), then from Saint-Florent to Belgod\u00e8re <\/strong>(61 km), before reaching Calenzana from Belgod\u00e8re <\/strong>(43 km). These stages cross the Balagne, an iconic region with hilltop villages and exceptional Mediterranean panoramas.<\/p>\n\n\n\n

The route continues westward from Calenzana to Gal\u00e9ria <\/strong>(31 km), then from Gal\u00e9ria to Porto <\/strong>(51 km). These shorter sections compensate with their technical demands, particularly the approach to Porto and its famous Calanques of Piana.<\/p>\n\n\n\n

<\/a>Most technical sections and high points<\/strong><\/h3>\n\n\n\n

The central section of the GT20 presents the most significant technical challenges, <\/strong>with the Porto to Col de Vergio stage <\/strong>(34 km). This section climbs to an altitude of 1,467 meters, the highest point of the entire route. It should be noted that this ascent is gradual but sustained, requiring a good level of fitness.<\/p>\n\n\n\n

The next stage, from Col de Vergio to Corte <\/strong>(50 km), offers a technical descent followed by a climb back up to the historic capital of Corsica. Corte is a must-see destination, rich in history and perfectly equipped to welcome cyclists.<\/p>\n\n\n\n

The end of the route goes from Corte to Ghisoni <\/strong>(57 km), Ghisoni to Zicavo <\/strong>(45 km), Zicavo to Zonza <\/strong>(44 km), to end with the longest stage Zonza to Bonifacio <\/strong>(71 km). This last section, although demanding due to its distance, fortunately benefits from a mainly descending profile towards the southern tip of the island.<\/p>\n\n\n\n

<\/div>\n\n\n\n

<\/a>Elevation changes and technical difficulties: understanding the altimetric profile<\/strong><\/h2>\n\n\n\n

Managing elevation changes <\/strong>is the most crucial aspect for successfully completing the GT20. With nearly 10,000 meters of positive elevation gain <\/strong>over the entire route, this crossing demands serious physical preparation and an appropriate pace strategy.<\/p>\n\n\n\n

<\/a>General altimetric profile and main mountain passes<\/strong><\/h3>\n\n\n\n

The total elevation gain of the GT20 <\/strong>is unevenly distributed across the sections, with significant concentrations on certain key stages. The highest point at the Col de Vergio, at 1,467 meters, <\/strong>represents the major challenge of the crossing. Nevertheless, the ascent from Porto is gradual, allowing for progressive acclimatization to the altitude.<\/p>\n\n\n\n

Other mountain passes punctuate the route, notably the Col de Bacino <\/strong>with its breathtaking views of the Gulf of Porto-Vecchio <\/a><\/u><\/strong>. These high-altitude sections present both technical challenges and exceptional panoramic rewards.<\/p>\n\n\n\n

Note that the overall profile favors morning climbs <\/strong>when temperatures are still mild. This natural organization makes it easier to manage effort and limits the risk of overheating <\/strong>, which is particularly beneficial during the summer season.<\/p>\n\n\n\n

<\/a>Most demanding passages and approach strategies<\/strong><\/h3>\n\n\n\n

Certain sections of the GT20 require a specific tactical approach <\/strong>to be completed successfully. The stage towards the Col de Vergio, in particular, demands an early start and careful hydration management <\/strong>.<\/p>\n\n\n\n

The climbs in the Alta Rocca region <\/strong>also present significant challenges, with gradients sometimes sustained over several kilometers. These sections require a suitable pace and regular breaks to avoid accumulating fatigue.<\/p>\n\n\n\n

Moreover, some technical descents require particular vigilance, especially towards Gal\u00e9ria or on the switchbacks <\/strong>leading to Bonifacio. Controlling braking and choosing safe lines become paramount on these winding sections.<\/p>\n\n\n\n

<\/a>Camping accommodation along the GT20: planning and booking<\/strong><\/h2>\n\n\n\n
\"The<\/figure><\/div>\n\n\n\n

Organizing camping accommodation <\/u><\/strong>is<\/a> <\/a>a crucial aspect for a successful GT20, particularly in high season when demand often exceeds available supply.<\/p>\n\n\n\n

<\/a>Recommended campsites per main stage<\/strong><\/h3>\n\n\n\n

The Les \u00celots d’Or campsite <\/strong>near Porto-Vecchio is a must-visit for cyclists on the GT20. Open from April 17th to October 15th, 2025, it offers specialized packages <\/strong>tailored to the needs of cycle tourists. The GR20 package, starting at \u20ac12 per night, includes one person and a tent, ideal for bicycle travelers.<\/p>\n\n\n\n

In the Calvi-Balagne region <\/strong>, several establishments specifically cater to GT20 cyclists. These campsites generally offer dedicated services: bike washing area, equipment drying, and route advice.<\/p>\n\n\n\n

the Merendella campsite <\/strong>in Haute-Corse<\/a> <\/a>has been developing a specialized GT20 offer. This establishment understands the specific needs of cycle tourists and adapts its services accordingly: flexible hours, enhanced breakfast, emergency bike repair.<\/p>\n\n\n\n

Other campsites are located along the route and offer preferential rates <\/strong>for holders of the GT20 guidebook. These discounts encourage cycle touring and facilitate budget planning <\/strong>for trips.<\/p>\n\n\n\n

<\/a>Booking strategies and optimal periods<\/strong><\/h3>\n\n\n\n

Booking in advance <\/strong>becomes essential during peak season, particularly between July and August. Be aware that campsites often apply minimum stay requirements <\/strong>during this period: 7 consecutive nights in July and August, and a minimum of 3 nights the rest of the year.<\/p>\n\n\n\n

Prices vary significantly depending on the time of year: from \u20ac12 in the low season to a maximum of \u20ac38 in the height of August for premium berths <\/strong>. This price variability directly impacts the overall cost of the crossing.<\/p>\n\n\n\n

In addition, some campsites offer all-inclusive packages <\/strong>including accommodation, enhanced breakfast, and sometimes luggage transport. These packages simplify the process but require booking well in advance <\/strong>. Here are the essential elements to check when booking:<\/p>\n\n\n\n
