OSA offers instruction in cross-country skiing and snowshoeing.

Wednesdays in January, February and March, take a break and ride with us to Ragged Mountain in Danforth, N.H. You’ll have a full day of skiing, lift tickets and rentals and a relaxing ride up and down for only $85.

Custom packages are available for you and your friends or business associates on other days, as well.

Sundays, January through April, join us for nature walks on snowshoes or on foot as we explore the wild world that’s very near to us. Kids are especially welcome, as we look for animal tracks in the snow and find all kinds of surprises in our extended back yard. Meet at OSA at 9:30 a.m. Tour will typically run until noon.

On the night of the full moon, join us for a magical look at what can be seen in our nearby nocturnal environment. In the quiet and the dark you can actually see more! See calendar for dates and times.
