Day 20 of a Camino de Santiago pilgrimage reads like a postcard of Galicia at its best: a pre-dawn start under headlamps, mist over green meadows, chestnut pods littering the path, and late blue crocuses pushing up between villages. The walkers in this instalment of a long-distance trekking diary cover an easy four-mile downhill stretch before reaching Sarria — the town where most short-route pilgrims begin their 100 km to Santiago — and where the character of the trail changes overnight.

That change is the story's real hook. Sarria marks the border between the quieter weeks of walking and the flood of newer pilgrims, who arrive with suitcases ferried ahead by luggage services and café routines the writer gently mocks. For anyone planning the French Way, it's a useful heads-up: book accommodation early and expect crowded mornings after Sarria, especially in high season.

The route itself rewards attention. This stretch passes through classic hórreos country — those raised stone granaries on stilts that dot Galician fields and have guarded harvests for centuries. And just before Barbadelo stands one of the trail's genuine landmarks: the Castiñeiro de Ramil, an 800-year-old chestnut tree with a nine-foot-wide, hollow trunk, dating to the 12th century. Back then, some 25,000 pilgrims a year passed its shade, and it still stands as the oldest living thing many walkers will meet on the whole route.

The emotional centrepiece is a return visit. In 2017 the writer stopped at Terra de Luz, a donativo refuge run by a man named Simon, who offers food, tea, couches and conversation to passing pilgrims. Eight years later, the refuge is still there, run on the same pay-it-forward model — one current volunteer described walking a stretch, then stopping to help for a while. The visit ends at the on-site quartz labyrinth, walked with a simple three-step instruction posted at its entrance: release, reflect, return changed. Donativo refuges like this operate on donations rather than fixed prices, and a stamp in your pilgrim passport here is a keepsake in itself.

Why does this matter to a traveller? Because the Camino is more than a walking route — it's a chain of small human institutions like Terra de Luz that have hosted pilgrims for over a thousand years. Knowing about places like this, and timing your walk to avoid the Sarria surge, turns a popular trail into a genuinely personal experience.
