The particularity of this Greenway is that it has very little unevenness (from Morata to Ambite it is almost flat). You don't come across any car (except for one of the shared sections) and the road surface is paved for practically the entire route, so it is very easy to accumulate kilometers without much complication.
The Tajuña Greenway Follows the route of the old Tajuña Railway, an agricultural train that went from Madrid to Aragon but never got past Alocén (whose station is currently deep in the Entrepeñas reservoir).
