Midcoast Conservancy’s Hidden Valley Nature Center (HVNC), 131 Egypt Road, Jefferson, will be offering several outdoor recreation options in the coming weeks, including cross-country skiing, snowshoeing and fat-tire biking. Trails are groomed and open daily — they are available free to conservancy members; nonmembers pay a $5 day-use fee.

Currently in session, a youth cross-country ski clinic is offered Saturday mornings from 9:30 to 11 a.m. through February 8. An adult cross-country ski clinic will be offered on Sundays, February 9 and 16; ski rentals will be available for all adult participants.

Monday, February 17, families are encouraged to ski at HVNC; skis will be available. Tuesday, February 18, the center’s fat-tire bike fleet will be ready for riders; helmets will be provided to those who don’t have their own. Registration is suggested for both events to ensure that equipment is available; visit midcoastconservancy.org to sign up.

Saturdays in February, from noon to 4 p.m., gear will be available for use at HVNC on a first-come, first-served basis. Skis, snowshoes or bikes can be rented by the hour.

The annual winter biathlon will be held at HVNC on Saturday, February 29, from 8:30 a.m. to 2 p.m. People of all ages and abilities are encouraged to participate in the event, which involves skiing, snowshoeing or fat biking, and shooting paintball rifles in a test of skills. Rifle safety instruction will be provided; four-person teams are welcome, and creative costumes might win a prize. To register, visit midcoastconservancy.org.
