Top Highlights for Backpacking in Gr20
Backpacking in Gr20
The GR20 slices 180km across Corsica's spine, earning its crown as Europe's toughest thru-hike with 12,000m of jagged ascent over loose granite, chains, and exposure. Backpacking here means total immersion in a Mediterranean wildness rivaling the Alps but with fewer crowds and more solitude. No paved paths or gondolas—just raw granite needles, hidden lakes, and pony-dotted plateaus that reward only the prepared.
Core experiences span 12-16 stages: scramble Cirque de la Solitude's death-defying gorge, summit Punta Eboulis at 2,607m for coastal vistas, and unwind at Lac de Nino's emerald shores. Variant routes add peaks like Tour 1, while refuges like Castel di Vergio offer hot meals amid beech woods. Nights blend gîte bunks, tent pitches, and starry bivvies, forging trail bonds over pastas and wine.
Hike late May to mid-October, dodging north-end snow until June; expect 30°C days and thunderous storms. Conditions swing from sun-baked rock to knee-deep mud—train for 8-12 hour days with 1,000m+ climbs. Prepare via fitness base and gear checks, as rescue costs €1,500+ and self-reliance rules.
Corsican shepherds and refuge guardians share charcuterie and tales of bandit history, infusing hikes with island defiance. Trail runners and thru-hikers form fleeting communities at dinner tables, trading route betas in French-English pidgin. This backpacker's rite taps authentic maquis culture, far from tourist coasts.
Conquering GR20's Wild Backbone
Book mountain refuges six months ahead for July-August peaks, as they fill fast; self-guided operators like The Natural Adventure handle logistics for £1,695 over 14 days. Start north-to-south from Calenzana for easier acclimation, or reverse for downhill finishes. Train with loaded 12km hikes boasting 1,500m gain to match the trail's brutality.
Pack light at 8-10kg max, prioritizing quick-dry layers for sweat and storms; water sources are frequent but treat with tablets. Train navigation via apps like Komoot, as granite slabs and variants confuse. Carry cash for refuge meals, as cards rarely work.
