Ladeira dos Moinhos is a short circuit beginning in the historic centre of São Roque do Pico. The start lies near an old bridge and the main church, in an urban setting that quickly gives way to a cobbled climb beside a stream. After only a short stretch of asphalt, the route enters the steep lane that gives it its name, where shade and running water help the surface retain moisture.
Several old mills appear during the ascent, positioned to use the force of the water. Even where structures are incomplete, they show the importance of this small watercourse to milling and village life. After roughly 1.2 kilometres, the path reaches an asphalt road and the rhythm changes. This upper section opens views across São Roque and its coastal strip, contrasting with the enclosed corridor of the mill lane.
After about 700 metres on the road, the markings turn into the descent. The return again follows a watercourse on a narrow path, partly bordered by a small wall, until it reaches the starting point. Its short distance and easy grade suit a brief walk, yet the inclined surface and persistent presence of water give the circuit a distinct character.
