Rat Penat is a mountain pass at an elevation of 600m (1,968ft) above the sea level, located in the Garraf Massif, mountain range of the Catalan Coastal Range, Catalonia, Spain. The winding asphalted road to reach the summit includes grades of 23%.
Starting from Sitges, a town about 35 kilometres southwest of Barcelona, renowned worldwide for its Film Festival and Carnival, at an elevation of sea level, the ascent is 5.17 km long. Over this distance, the elevation gain is 477 meters. The average percentage is 9.2 %.
The surface of the road is asphalted. Rat Penat (also called Turó del’Alzina Freda) has been climbed several times on the Vuelta a España. With grades a couple of ramps of 23% this is the local Mortirolo. For professionals like Juan-Antonio Flecha this is an opportunity to do some serious interval training in preparation for the Spring Classics like the Tour de Flanders and Paris-Roubaix. The road is difficult and it’s a nightmare in the wet or dark (or both).
The experience of using this road is very impressive. The road becomes specially dangerous to control the speed on the tight hairpins on the way back down. The last 2km of the road to access the summit are forbidden to cars. This is a very hard climb, with irregular incline with very few breaks. The climb allows marvelous sights on the coast as it is close to the sea, between Castelldefels and Sitges.
