The Ecopista is predominantly a car free zone, with the exception of the first 1,5 kilometres near the Santa Comba Dão train station which has a small residential area where Road and Ecopista are combined.
The Ecopista do Dão is known to be the longest Ecopista in Portugal with easy cycling and beautiful views along the Dão river. It was once known as a railway line from Santa Comba Dão to Viseu until 1988, then converted into one of the main attractions cycling and walking paths.
