Kalupahana-Horton Plains road is named as one of the world's most adventurous roads by the Huffington Post in its list of 'Wildest Roads Around the World'.

Nicknamed Satan's Steps in colonial times and ascending 4,236 feet over just 15 miles, this jaw-chattering jeep track through Sri Lanka's highest plateau has steep switchbacks, including one called the Devil's Staircase. Experienced drivers can expect glorious hill-country landscapes, with tea plantations, waterfalls--including Sri Lanka's highest, Bambarakanda--and a refreshingly cool climate, the Huffington Post states.

The report further states, the road leads from Kalupahana on the Colombo-Badulla highway to the Horton Plains National Park visitor center via the Udaweriya Estate. To drive farther into a protected part of the park requires a permit from the visitor center. The best driving conditions are January through March.
