The northern gateway to the greenway
Santo Adriano
Santo Adriano is where you enter the greenway coming from Oviedo, and its reference village is Tuñón: free parking (~40 spaces), a recreation area with a fountain and the start of the first section opened as a greenway in 1995.
300 metres from the path waits the municipality's great surprise: the pre-Romanesque church of Santo Adriano de Tuñón, consecrated in 891 AD, with Mozarabic paintings — an eleven-century-old monument just a three-minute detour away.
Between Tuñón and Proaza the municipality also offers the route's two gorges (Peñas Juntas and Valdecerezales) and the Buyera area, with picnic tables, a fountain and the entrance to the bear enclosure. The full guide is in Santo Adriano.
