Among the natural attractions of the parish is a feature known as the Devil's Hole (), a
blowhole in the cliffs of the coast. The descent from the car park to the Devil's Hole is a popular tourist attraction, with the walk taking approximately ten minutes. The upper part of the path is surfaced, and the lower part, once quite dangerous in parts, now has wooden steps and handrails, with much of the access having been improved by a working party from the
Royal Engineers Corps of the British Army. In Victorian times it was possible to descend into the hole itself at low tide, but this is no longer possible. However, the access path ends at a large specially constructed viewing platform. The origin of the name is disputed. refers to a chasm within a cliff-face. It is possible that was corrupted into an anglicised 'Devil'. It may also get its named from the statue of the devil, as it is unknown whether that predates the modern name. Following a shipwreck in 1851, when the ship's
figurehead washed up in the Devil's Hole, a statue of a
devil adapted from the figurehead was set up above the Hole. This wooden statue was replaced by a succession of modern versions in the 20th century. Grève de Lecq is shared with St Ouen.
Grève is the Jèrriais word for beach.
Lecq originates from the Norse
La Wik, which may have meant 'ship-loading creek' or referred to witches, should the bay have been a centre of sorcery. ==Twinned towns==
