It is 4 miles from Ramsey and is located in the parish of Kirk Christ Lezayre on the A3 Castletown road.

[1][2] Historically containing the Treen of the Curragh of Kirk Christ Lezayre and the Land of the Monks of Myrosco, the village is situated at the southern edge of the island's northern alluvial plain; north of the island's northern hills; at the point where the Sulby River emerges from those hills.

The village is dominated by the Sulby River, the Ballamanaugh farm estate, common land of the Claddagh and Cronk (hill) Sumark, which includes the remains of a fort from the Iron Age.

[9] During a practice session for the 2006 Isle of Man TT races, New Zealander Bruce Anstey achieved the unofficial current top speed record of 206 mph (332 km/h) at the end of Sulby straight near the Kella crossroads.

[11] The notorious hump-backed Sulby Bridge on the A3 road located at the eastern end of the Sulby Straight (built c.1815),[12] considered at the time to be the most difficult part of the TT Course for motor-cycle competitors, was removed in 1922-23 by the Isle of Man Highway Board.
