The snow in Halifax rarely piles up much, but walking trails at any HRM parks can be used for cross-country skiing; a city employee recommends the former railway lines at the Musquodoboit Trailway and the Timberlea trails. Martock is the official Winter Games venue, and has cross-country programs offered for adults and kids (see also Biathlon). A Saturday morning learn-to-ski program is offered from January 8 to March 12, for $80; the biathlon program runs Saturday afternoons for the same dates and cost. A trail pass is $21 daily, $39.95 with equipment rental, or $159.95 for a season pass. Wentworth has cross-country skiing as well, at the top of the mountain and accessed by chairlift, for the intermediate to advanced skier.
