The Chalcedony Trail (PR1 TBR – Trilho da Cidade da Calcedonia) is one of the most iconic routes in Peneda-Gerês National Park, located in Covide (Braga), within the municipality of Terras de Bouro. It leads to the ruins of the City of Chalcedony, an ancient pre-Roman hill fort high in the mountains. It offers panoramic views over the Homem River valley and the Gerês mountains. The trail passes through native forests, rocky areas, and natural viewpoints.

The Calcedonia Crack is one of those passages that seems to have come straight out of an old fairy tale: a monumental crack between two granite giants. For those who like a challenge, the route involves climbing and jumping between huge blocks fitted together at the base. Going up is easier than going down: there is more support, more traction, and less hesitation. There is no need to cross it (the trail elegantly skirts the crack) but, for the more adventurous, facing this crack is almost a ritual: a mix of adrenaline, vertigo and raw landscape that leaves its mark on those who pass by.

As the climb progresses, the granite boulders become increasingly imposing, sculpting the landscape with impressive shapes and dimensions. To the south, Curvaceira rises, the highest point in the area, at 919 metres above sea level. To the north, a wide view opens up over the Covide valley. Here, Barrosã cows roam freely across the hills, while the mountain landscape reveals itself in all its grandeur above 800 metres. But this is also the most challenging part of the climb: narrow trails, a steep incline and some rocks that require a bit of climbing.

We hiked the Covid loop (yellow and red lines) clockwise. The ascent was OK. The rocky landscape was spectacular. The Slut was also impressive, but considering the many rocks, it was just another somewhat more exclusive highlight among many. The descent, however...described in Komoot as well-maintained hiking trails, no special skills required. It's an overgrown trail with (very) high steps and scree sections. Very good fitness and surefootedness are required to safely navigate it. The less than three hours for the loop is also very ambitious. At the end of the descent, there was a dog park with some very aggressive dogs running loose on the trail; we felt like we barely made it through unscathed. Next time, I'd turn around at the Slut and take the same route back. Be sure to bring plenty of drinks. Great scenery, very tiring.
