The government says it's banned camper vans from a popular beauty spot in the north of the Island.
Motorhomes and camper vans are no longer allowed to camp overnight at the Ayres National Nature Reserve.
The government says campers have damaged turf on dune grasslands and a number of vans got stuck there over the last year - it adds police have been called over camp fires and vehicles driving at high speeds.
Environment, Food and Agriculture Minister Clare Barber says although the vehicles can still visit the area, they won't be allowed to stay overnight.
