    The Siete Revueltas are one of the most iconic sections of the road that ascends to the Navacerrada Pass.

    This section consists of seven hairpin bends, one after the other, marking the final and toughest part of the climb from the Segovia side.

    One of the most well-known bends that appear on the way up to Puerto de Navacerrada on the north side, from Segovia. Curves that have become internationally famous because of the Vuelta España but which have always been important to the locals of the Sierra!
