NORTH BOULDER PARK (easy) This open, level lawn between Eighth and Ninth streets and Alpine and Dellwood avenues is popular after heavy snowfalls. BNC sets up skate-skiing and diagonal touring tracks with groomed trails. Volunteers usually groom this first after a big snow. The loop is a 2k round-trip. Please keep dogs on leash. ♦

OTHER CITY PARKS To find out if any other city parks are being groomed by BNC volunteers, check the grooming report at bouldernordic.org.

Brainard Lake

From Boulder Canyon Drive (Highway 119), take Colorado Highway 72 north to Ward and turn west onto the Brainard Lake Road. Travel 2.5 miles to the Brainard Gateway Trailhead and parking lot. The bathrooms and warming hut are open for public use. There are no trash facilities available, so all trash, including pet waste, must be carried out.

During the winter months, dogs may not be on any of the trails, but are allowed on the road. Trails are marked with blue diamonds or brown-and-white cross-country trail markers. Snowshoe trails are separate from those for skiers to minimize conflict between the two user groups. There is no maintenance on trails during the winter, so be aware of adverse conditions.

Groups of more than 8 people need a permit to enter the Indian Peaks Wilderness, and groups are limited to 12 people. Permits are available at the U.S. Forest Service Office, 303-541-2500. The Colorado Mountain Club’s Brainard Cabin is typically open on weekends from 10:30am-2:30pm, with coffee and hot chocolate through March, for $1 donation per visitor.

After about a half-mile, take a right from the Lefthand Reservoir Road to the Little Raven Extension Trail for about a half mile, and another left onto the Sourdough Trail takes you back to the Gateway Trailhead in another half-mile.

LeftHand Park Reservoir road (moderate) Begin just past the winter road closure gate and follow the winding uphill road to Left Hand Park Reservoir, crossing cutoffs for the CMC Trail and Little Raven Trail on the way. The last quarter-mile is exposed to severe winds off Niwot Ridge. Then return for a 4-mile round-trip.

Long lake/lake isabelle trail (moderate/advanced) Follow CMC South Trail (above) west of Brainard Lake to Long Lake trailhead. At approximately 1.5 miles, the trail splits. The left fork, the Jean Lunning Trail, loops around Long Lake for a 7-mile round-trip. The right fork also loops the lake. At the far end of the loop is  the cutoff for the Pawnee Pass Trail with a steep 1.6-mile climb to Isabelle Lake.

Mitchell Lake/Blue Lake Trail (moderate/advanced) Follow CMC North Trail (above) west of Brainard Lake, turn right and continue 1 mile to Mitchell Lake trailhead. Climb steadily through the trees to Mitchell Lake for a 7-mile round-trip from the trailhead. Blue Lake is another 1.3 miles up the trail.

RED ROCK LAKE TRAIL (easy) This very short, easy trail is a scenic out-and-back, great for families with very young children.

SNOWSHOE TRAIL (easy/moderate) This trail was developed especially for snowshoers. It’s marked with blue-diamond trailblazes and snowshoer symbols. Start on the Lefthand Park Reservoir Road.

The parking lot is about a half-mile up the dirt road on the left.

CARIBOU RANCH OPEN SPACE (easy) The lollipop trail system is a total of 4.5 miles round-trip from the parking lot. The trail partially follows a historic railroad bed and passes an old homestead and mining camp. The conditions are usually better for snowshoeing than skiing.

RAINBOW LAKES ROAD (easy) Take the left fork about a quarter-mile west of the Sourdough Trailhead to ski or snowshoe to Rainbow Lakes. The route is gradual and open, rolling up- and downhill. It is often windblown, bare and icy in patches, but makes a good trip for novices in favorable snow conditions. It is 4.5 miles to the Rainbow Lakes Campground. A trail continues west from the campground for 1 mile to Rainbow Lakes.

Rocky Mountain National Park

The Rocky Mountain National Park Beaver Meadows entrance and the Visitor Center on U.S. Highway 36 offer maps detailing 40 miles of marked trails near Bear Lake and Glacier Gorge, plus 88 miles of mostly unmarked trails in Wild Basin (accessed off Colorado Highway 7, a mile north of Allenspark). 970-586-1206; www.nps.gov/romo.

Black Lake (moderate/advanced) From the Beaver Meadows entrance, take U.S. Highway 36 to the Glacier Gorge Junction parking lot. Head up Alberta Falls/Mills Lake Trail, taking the right fork at the 1.3-mile point. At the next junction, take the left fork to Glacier Gorge (the right fork leads to Loch Vale). At Mills Lake, you have a choice. The snow is usually reliable through the trees on the east shore, but if the lake is frozen under snow, ski right across it. Pass Jewel Lake and climb to the alpine cirque of Black Lake. It’s an 8-mile round-trip.

Emerald Lake (easy/moderate) From the Beaver Meadows entrance, take U.S. Highway 36 to Bear Lake Road and the Bear Lake parking lot. From there, follow trail markers past Nymph and Dream lakes to Emerald Lake. It’s a 3.6-mile round-trip.

Wild Basin (varying difficulty) Take Colorado Highway 7 for 1 mile north of Allenspark. Turn west at the Wild Basin entrance. From the winter parking lot, the road connects with moderate trails to Calypso Cascade (3.6-mile round-trip) and Ouzel Falls (6.2-mile round-trip), and strenuous jaunts to Bluebird, Thunder or Lion lakes (each an 11.6-mile round-trip).

Nederland/West Magnolia

From Nederland, head south on Colorado Highway 119 for about 0.75 miles. Turn west onto County Road 132W. Continue 1 mile west and turn south through the second Forest Service gate to the main trailhead parking area. The West Magnolia trail system was developed mostly by mountain bikers, but it can provide fun skiing or snowshoeing immediately after a good snowstorm. Navigating the area’s numerous trails can be tricky and frustrating, so take a map and keep a sharp eye out for trail markers and the occasional map kiosk. From the trailhead, take your pick of routes (varying difficulty) and let the snow and trail conditions be your guide. ♦
