Mountain biking is one the most popular activities for the Madrileños and there's a good reason for it: the city is full of opportunities for entertaining outings. Madrid’s city forest — Casa de Campo, for example, is an excellent option for a Mountain biking day trip. This urban outdoor paradise lies just 10 minutes from the city center, but takes you into a completely different setting. Find peace and quiet and a whole lot of mountain biking fun.  Take a 10 minute drive from town and give the challenging down hills and climbs of “El Pardo” a try or drive just half an hour further to a mountain area you’d never expect to find so close to a city like Madrid. This 150,000-acre National Park of Sierra de Guadarrama is an adventure for every mountain biker.
