The legendary mountain section of the Isle of Man TT course.

The A18 Mountain Road climbs over the shoulder of Snaefell between Douglas and Ramsey, the fast, sweeping mountain section of the TT course, with no general speed limit on parts but exposed, unforgiving terrain. Respect the conditions, the gradients and other road users.

Fast, flowing tarmac across bare moorland, with the TT course’s legendary mountain section unspooling beneath you and the sea on every side.
