From the NCC Gatineau Park website:
Gatineau Park will be hosting the Gatineau Loppet this weekend. The trails will not be closed to recreational skiers during this event, however competitors should have priority. Please avoid using parking lots P1 (Asticou), P2, P3, P5 and P6. For more information: www.gatineauloppet.com.
Please note that during the Gatineau Loppet, Huron shelter will be occupied day and night by a group of Canadian Cadets.

The cards that GuideGatineau has begun distributing to promote the website are considered to be highly environmentally responsible due to the fact that the paper used is 100% recycled and is produced using energy from biofuels plus the ink is vegetable based.
