Trail context
A certificate grounded in the journey.
GR20 crosses Corsica's rugged mountain spine through granite ridges, steep passes, forest, exposed rock, and a sequence of refuges. It is commonly recorded as separate daily activities, and technical terrain or battery limits can leave gaps in otherwise credible tracks. Submit the strongest route files available, add dated photographs at refuges or distinctive mountain sections, and use booking or itinerary context where it clarifies the stage order. State the direction, start and finish, rest days, and any escape or transport section. The certificate's Corsican granite landscape is designed to recall the route while remaining independent of French or trail authorities. Every identifier uses the `GR20` code. Raw GPS, refuge details, photographs, and private messages remain outside public verification. The public page preserves only safe completion metadata.
Completed GR20? Submit route-appropriate GPS tracks, activity links, dated photos, stamps, permits, guide confirmation, club confirmation, or a clear completion narrative. Route variants are assessed from the evidence provided.

Private review layer
Your proof is not your public profile.
Reviewers may see
GPS and activity files, uploaded photos, permits, stamps, guide confirmations, completion narrative, and clarification replies.
The public may see
Certificate status, trail, privacy-controlled display name, dates, verification level, issue date, fingerprint, and registry signature state.
Supported route variants
Accepted itineraries range from approximately 175 km to 185 km. The certificate must identify the completed variant or section and any transport links.
State direction, start, finish, refuge sequence, weather diversions, and any skipped or transport-assisted section. The certificate ID and trail code must always use GR20, never the legacy single-letter code.
