Parks Canada says it will not make an exception for snowmobilers who want to use their machines in a limited corridor out of Terra Nova National Park.

Protesting snowmobilers openly defied a ban on snowmobiles in the park Sunday when more than 50 machines drove west on an illegal trail from Charlottetown into the park and then returned home.

Charlottetown is surrounded by the central Newfoundland park. The protesters argue they should be allow to establish a corridor to drive snowmobiles through it.

Park officials said snowmobiling is prohibited in the park for sound reasons.

"Parks are created for people to use, but in such a way that they are unimpaired for future generations and snowmobiling does cause damage to the park. It impacts the visitor experience and it does cause public safety concerns as well for us," said park superintendent Bill Brake.  

Park Wardens monitored the protest, but didn't intervene.

Brake said no one was stopped Sunday because wardens were busy making sure everyone was safe. However, he said park officials are going to takes steps to try to prevent people from using snowmobiles in the park.

Some people who live in Charlottetown said park regulations restrict them from traditional outdoor pursuits, such ice fishing and berry picking.
