Step back 2,000 years by walking a section of the Geira, the ancient Roman road that once connected Braga in Portugal to Astorga in Spain. This remarkable feat of engineering passes through the heart of the Peneda-Gerês National Park. One of the best-preserved stretches lies within the Mata de Albergaria forest, where you can walk on the original Roman flagstones and see ancient milestones that still stand by the roadside. It’s a unique hike that combines breathtaking natural beauty with a powerful sense of history.
