Sgùrr Dearg (Scottish Gaelic for 'red peak') is a mountain in the Cuillin on the Isle of Skye, Scotland. It is topped by the Inaccessible Pinnacle (colloquially referred to by mountaineers as the In Pin or In Pinn), a fin of rock measuring 50 metres (150 feet) along its longest edge. The top of the Inaccessible Pinnacle, which at 985.8 m (3,234 ft) is the highest point of Sgùrr Dearg and the only Munro with a peak that can only be reached by rock climbing. This makes it the biggest hurdle for many Munro baggers.
