The valley of the Tagus River, in the province of Madrid, is a unique landscape of agricultural meadows traditionally dedicated to irrigation, gardens, and hydraulic resources exploited for several centuries through water mills, fulling mills, ditches, and hydroelectric plants, which have utilized the riverbed as a source of energy and natural resource.

In the municipality of Estremera is the Los Villares inland beach, equipped on the banks of the Tagus with sand and trees. It is one of the five places in the rivers of the Community of Madrid where swimming is allowed, it has a recreational area and services during the summer season, and has easy access from the route of the cycling path, facilitating visits from Estremera, Brea de Tajo, and Fuentidueña de Tajo.

The second part of the route is an entertaining leg-breaker along the Natural Path of the Eastern Soriana Cañada, from the banks of the Tagus, in Fuentidueña de Tajo, to the farmlands and oak hills of Brea de Tajo, at the border with the province of Guadalajara. Along the way, it crosses the Uclés Path and the route of the 40 Days Train, in the moors of the municipality of Valdaracete, completing a varied itinerary through places of notable environmental quality, historical towns, old railways, and remnants of a castle that was the seat of the Order of Santiago.

The passage through the popular tunnels of the 40 Days Train is simple and fun. They are at the beginning of the route, the surface inside the tunnels is good and there is no need to carry a light, as natural lighting is sufficient, taking precautions in the longest tunnel.

Types of path:

• Paved section: 2.1km
• Path section: 38.5
