This is undoubtedly the most famous pass in Mpumalanga - and with good reason too. It is 26,2 km long (and even longer depending on where one starts measuring), plus it displays an altitude variance of 671 vertical meters through a complex network of curves as it ascends up the Drakensberg escarpment between Sabie in the east and Lydenburg in the west. The pass forms part of the Mpumalanga Panoramic Route and carries appropriately heavy traffic - both tourist and commercial. It is prone to heavy mist and can be dangerous in low visibility conditions. It is named after the famous Long Tom cannon.
With 66 bends, corners and curves and a fairly easy average gradient of 1:39 and no part being steeper than 1:10 this pass is a magnificent spectacle with grand views and rugged frontier and Anglo-Boer War history adding to its allure.
