June and September offer ideal conditions: pleasant temperatures (22-28 degrees C), sea warm enough for swimming, moderate crowds and reasonable prices. July-August also work but the heat is intense and tourist hotspots are packed. Spring (April-May) is perfect for hiking with the maquis in full bloom, while autumn (October) delivers Mediterranean mildness with few tourists. See our complete seasonal guide for more details.

The GR20 is demanding but accessible to any hiker in good physical condition with proper preparation. The 180 km trail with over 12,000 m of cumulative elevation gain takes 12 to 16 days. The main difficulties are technical rocky passages (slabs, scree, chains), significant daily elevation gains (800-1,200 m) and variable high-altitude weather. The northern section (Calenzana-Vizzavona) is considerably more technical than the south. Several months of physical preparation and proper gear are essential. First-time trekkers will benefit from a professional guide.

Corsica is an exceptional family destination. Easy hikes such as the Cascade des Anglais at Vizzavona (45 min), the forest trails of Bonifatu or the customs officers' trail at Cap Corse are suitable from age 4-5. River swimming in the natural pools of the Fango or the Solenzara thrills children. Boat trips to the Lavezzi Islands or the Bonifacio cliffs create unforgettable memories. Our family activities guide covers all the options by age group.

The essentials are: ankle-high hiking boots with lugged soles (the granite terrain is demanding), 2-3 litres of water per person (summer heat is fierce), SPF 50 sunscreen, a hat, sunglasses, a lightweight waterproof jacket (mountain storms are sudden), an IGN map and a phone with offline maps. For the full list, see our complete checklist.

It depends on the activity. For hiking on waymarked trails, going self-guided works well for prepared walkers with a map and the right gear. However, canyoning requires a certified guide (for both safety and regulatory reasons). Via ferrata is recommended with a guide for beginners. Boat trips into nature reserves are run exclusively by licensed operators. For the GR20, a guide is recommended for trekking novices. Our detailed comparison analyses each situation.

Among the hikes suited to occasional walkers: the Cascade des Anglais at Vizzavona (1h30 round trip, shaded trail), the Lake Melo loop in the Restonica (3h, spectacular glacial cirque views), the Piana calanques (maintained trail with breathtaking panoramas), the coastal path between Ajaccio and the Sanguinaires islands (3h, continuous sea views) and the Spelunca gorges between Ota and Evisa (2h, Genoese bridges and rock pools). See our hiking guide for full details.

Natural pools present real risks that should not be underestimated: slippery rocks (wet granite is treacherous), variable currents depending on recent rainfall, uneven depths and cold water (12-18 degrees C at altitude). Accidents occur every year, often from diving into insufficiently deep areas or slipping on rocks. Wearing water shoes, never diving without checking the depth, supervising children at all times and never swimming alone are the basic rules. Low-altitude river pools (Fango, Solenzara) are generally safer than high-mountain ones.

Budgets depend on your travel style. Budget (camping, self-guided): 50-80 euros per person per day (accommodation, food, transport). Mid-range (guest house, some guided activities): 120-180 euros/day. Comfort (hotel, guided activities, restaurants): 200-350 euros/day. On top of that, add transport: ferry with car from the mainland (150-300 euros return depending on the season) or flights (80-200 euros). Car hire on the island costs 40-80 euros/day in summer. Hiking is free, but guided canyoning (50-70 euros), boat trips (40-80 euros) and diving (50-80 euros) are additional costs.

Highly recommended, yes. Public transport exists (Bastia-Ajaccio-Calvi train, seasonal coastal buses) but frequencies are limited and trailheads are rarely served. Corsican roads are narrow and winding: allow 30-50% more time than the GPS suggests. Choose a compact vehicle, which is more manoeuvrable on mountain roads. Book early for July-August: demand far exceeds supply. Alternative: for a stay focused on a single area, some seasonal shuttles and local taxis may suffice.

The must-dos are: the Scandola Reserve (UNESCO site, red porphyry cliffs, sea caves and protected wildlife), the Piana calanques from the sea (spectacular rock formations), the Bonifacio cliffs (citadel perched on white limestone cliffs, sea caves), the Lavezzi Islands (granite archipelago with crystal-clear waters, ideal for snorkeling) and the Gulf of Porto coves. Trips last 2-8 hours depending on the itinerary. See our guide to boat excursions for details.

Corsica is one of the safest regions in Europe in terms of fauna. There are no venomous snakes on the island. The green whip snake (Hierophis viridiflavus) is present but completely harmless. No dangerous scorpions, no bears, no wolves. The only animals to be cautious around are free-roaming cows and pigs on some trails (keep your distance, especially from mothers with young) and wild boar (shy but unpredictable if they feel cornered). At sea, jellyfish may appear in summer but are sporadic.

Reliable sources are: IGN 1:25,000 maps (Top25 series, available in print and digitally via the IGNrando app), FFRP topoguides (especially for the GR20 and Mare a Mare/Mare e Monti routes), the Corsican Regional Nature Park (PNRC) website for refuge and trail conditions, and local tourist offices for same-day conditions. The Visorando and AllTrails apps offer community-contributed GPS tracks. Our hiking guide brings together the essential information on the main routes.
