Numerous urban climbing walls are found everywhere. It is needed to highlight those that are free and that its facilities are made through what is pre-existing in the city; it can be a bridge, a wall, a building, etc.
All these examples are found in Madrid, where people try to climb in different places just to give another use to the city. In the arcades of the French Bridge near Ciudad Universitaria, a small climbing wall was discovered. In the Cuesta de la Vega, climbing can be practised on the stone retaining wall that is around 9 metres high- there are some ways to practice and the level of difficulty is good for learning-.
