Referred to as Parque Florestal de Monsanto, this is the largest green space in Lisbon. It has a large variety of terrain, from forest trails to pedestrian and cycling paths, and several active recreation areas. There are several surviving mills, dating back to the park’s more agricultural era. There are playgrounds, swimming pools, and playing fields. Also some good hill opportunities. Great views from the top.
We don’t proscribe a particular route here. One can put together several kilometers of great running in here. See the map below. Another opportunity is to connect to the Green Corridor of Lisbon (Corredor Verde de Monsanto), a recently completed linear park, which heads nearly 2 miles southwest to Parque Eduardo VII. Look for the red pavement.
