Cairnwell Pass is a mountain pass at an elevation of 670m (2,199ft) above the sea level, located in the Scottish Highlands. The road to the summit is called A93.
The pass is located between Glenshee and Braemar. At 670m, it is the highest main road in the United Kingdom. At the summit is the Glenshee Ski Centre, Scotland's largest and oldest ski centre. A mile south of the summit is the Devil's Elbow, a double-hairpin bend climbing at a gradient of 17 percent. The Devil's Elbow has been bypassed since the road was rerouted in the 1960s but can still be walked or cycled.
This road is usually open all year, but it can be closed anytime when the access is not cleared of snow. The pass follows the military road built by William Caulfeild in the 1750s and was used by drovers to take cattle and sheep to market.
