From Castrojeriz to Frómista is 24.7 km along the French Way (Camino Francés). It's stage 15, with 201 m of ascent and 233 m of descent, completed in about 5 h 30 min. Difficulty: Easy.
A stage of endless horizons
The stage opens with the day's main challenge: a steep climb up the Alto de Mostelares, with 145 metres of elevation gain over just 1.7 km. From the top, the views across the Meseta are immense, setting the tone for a day many pilgrims describe as unforgettable for anyone who loves solitude, silence, and endless fields.
The route passes through Itero del Castillo and crosses the Puente Fitero, a medieval eleven-arch bridge over the río Pisuerga that marks the boundary between the provinces of Burgos and Palencia, and once between the Kingdom of León and the County of Castilla. It continues through Itero de la Vega and Boadilla del Camino, with its 15th-century Gothic jurisdictional pillar beside the church.
The stage ends in Frómista, home to one of the jewels of Spanish Romanesque art: the Church of San Martín, built in the second half of the 11th century and considered one of the prototypes of European Romanesque architecture.
