The LP-4, known as Carretera del Roque, is an absolutely beautiful road, with many different turns and twists, almost without traffic located in the province of Santa Cruz de Tenerife of the Canary Islands. It's one of the highest roads of the country.
The road is asphalted but pretty steep, climbing up to 2.306m (7,566ft) above the sea level. It provides access to the Roque de Los Muchachos road, the highest point on the island. The road links the city of Santa Cruz de la Palma and the town of Hoya Grande. Avalanches, heavy snowfalls and landslides can occur anytime, being extremely dangerous due to frequent patches of ice. Due to the high mountain characteristics of the road, it’s recommended extreme caution on driving.
Located within the Caldera de Taburiente National Park, the road is 49.9km long. There are sheer drops virtually along the entire route and enough hairpins to make a whirling dervish dizzy. Fog, clouds and snow make the road dangerous. The road is not easy, though. Up, down, right, left all the time. Driving at night, or in poor visibility, is not recommended for drivers unfamiliar with the road. This route is not recommended if your passengers are prone to car sickness due its hundreds of sinuous curves with some hairpin turns. Don’t stuff your belly too much. Eventually, you might feel vomiting temptations. The road is beautiful and offers spectacular views, but since it is a mountain road, you have to climb slowly and carefully.
