List of named corners of the Snaefell Mountain Course

Course with selected corners marked

The Snaefell Mountain Course, a motorsport racing circuit that was once part of Grand Prix motorcycle racing, has more than 60 named corners, bends, straightaways, and other features. Unlike the closed-circuit race tracks now used in all Grand Prix championship races,^{[note 1]} the course runs 37.73 miles (60.72 km) almost-entirely along public roads of the Isle of Man.^{[note 2]}

This list includes prominent corners and other landmarks along the course with names that are used in media coverage and by racers, spectators, and administrators.

Marker flag for a left turn

The number of turns in the course is debatable – writing in his 1974 book, TT racer and motorcycle journalist Ray Knight mentioned that the Guinness Book of Records quoted 264, echoed by a 2011 report.^[1][2] Some of the curves, S-bends, turns at crossroads, and other features in the course would not seem significant to car drivers in public traffic, while they are very significant for high-speed racers. 133.962 mph (215.591 km/h) is the highest average speed over one lap of the course that has been attained, by Michael Dunlop on 10 June 2016.^[3] At jumps where most race machines rise clear off the ground, drivers of cars at slow speeds might not even notice a bump. At each corner, racers must consider adjusting their entry speed, focus on their pre-planned line, lean according to the nature of the turn, and anticipate accelerating, decelerating, turning again, or otherwise handling their machines as needed while exiting the turn.^[4]

During race season there are road-side marker boards, first introduced as banners in 1921,^[5] posted in advance of the major features bearing these names to inform practice racers, and during races may remind racers what is coming.^[6] The turns generally aren't labelled by numbers as on short racing circuits.

Spectators also focus on named corners and other landmarks beside the course; many of the best vantage points are at turns where racers can be better-seen as they slow down. As a guidebook for visitors to the Isle of Man describes:

Spectators gather all around the course at locations which have become part of road-racing history: Bray Hill, Quarter Bridge, Ballacraine, Laurel Bank, Baaregarrow, Ballaugh Bridge, Quarry Bends, Sulby Straight, Ramsey Hairpin, Gooseneck, Verandah, 32nd Milestone, Windy Corner, Kate's Cottage, Creg-ny-Baa, Hillberry, Signpost, Governor's Bridge.^[7]

Naming Practices

While there exist named turns in other racing circuits, naming of corners and other turns elsewhere is usually less salient. For example, there is the notable "Dunlop Curve" of the 24 Hours of Le Mans' automobile race circuit and motorcycle race circuit. But the turns in many courses are primarily referred to by numbers, e.g. turns of the 1909-built Indianapolis Motor Speedway in the U.S. are referred to as Turn 1 through Turn 4. The Snaefell Mountain Course is one of the longer racing circuits and has more turns.

In common with corners on other circuits that are named, many are named after champion racers, and examples in the Snaefell course are Joey's Corner at the 26th Milestone, posthumously-named there to commemorate the 26 racing victories by racer Joey Dunlop on this course prior to his death racing in Estonia, and Hailwood's Rise/Hailwood's Height, named after famous rider Mike Hailwood, killed in a road traffic accident in central England. A change to the naming-convention occurred in 2013 when McGuinness's and Molyneux's were named in honour of living rider John McGuinness and sidecar driver Dave Molyneux, ranking second and third in the tally of TT race wins.^[8]

Some corners in the Snaefell course are named for riders who suffered accidents at the corner or nearby: Doran's Bend after Bill Doran and Brandish Corner, after Walter Brandish. Others refer to the corner's physical shape: Verandah, The Nook. More take names of nearby artificial or natural landmarks: Creg-ny-Baa (a pub), Tower Bends, Bray Hill. Landmark-based names may continue to be used long after their namesake is gone: Keppel Gate, Signpost Corner.

Course marked in red

The roads serve two-way public traffic for most of the year, and are closed during practice times and races. For the entire racing season of several weeks in May/June and August/September, the mountain portion of the course (from Ramsey to Douglas) is restricted to one-way in the race direction, and parking is prohibited from various areas.^[9] These and other provisions allow inexperienced racers and visiting motorcyclists to learn the corners and informally practice on the course.

The following is a partial list of named corners and other landmarks along the course. Turns described as left- or right-handers assume that travel is in the race direction, which is clockwise around the circuit.
