Enduro riders are being warned they can face prosecution if they ride cross-country.
At the weekend, police say incidents were reported of riders crossing heathland at Snaefell, Ballaugh and Slieau Freoaghane in Kirk Michael.
Officers say the land is protected under the 1984 Forestry Act and you can face prosecution if you're spotted.
Their advice is to stay on tracks.
