Cross-country skiers: It's time to polish off the gear and head to a Ramsey County park.

Ramsey County Parks and Recreation staff began grooming trails Friday. All trails have been rolled and packed, and are open for use.

Trails will continue to be groomed throughout the season after each significant snowfall and tracks will be maintained as long as a 6-inch base of snow is available, according to county officials

Ski trails are generally groomed after snow removal is complete at major parking lots and recreational facilities.

Cross-country ski trails are available at five locations in the Ramsey County parks system: Battle Creek Regional Park East, Battle Creek Regional Park West/Winthrop, Grass Lake, Vadnais-Sucker Lakes and Tamarack Nature Center.

Trail maps and grooming updates are available on the Ramsey County Parks and Recreation website at http://parks.co.ramsey.mn.us.
