Peninsula State Park
Parking lot 1
- White Loop (1.5 miles, esy). A bit more difficult than the yellow loop, but still geared for beginners, this trail has several gentle hills. Skiers tour through stands of cedar and spruce and along marshes adjacent to Green Bay.
- Black Loop (3 miles, moderate). Skiers of intermediate skill levels will enjoy the varied scenery and topography. There is one very steep uphill climb where the trail separates from the white loop. Skiers should remove their skis for this one. The black loop takes skiers through relatively remote pine forest over gently rolling terrain. Watch out for the steep curving hill on the last half-mile section.
- Brown Loop (3.5 miles, moderate). Skiers of intermediate skill level will enjoy this loop. This trail continues with the black loop up the very steep uphill climb where skiers should remove their skis. The brown loop has one challenging downhill stretch where the trail merges with the purple loop.
- Purple Loop (5.7 miles, difficult). This is Peninsula’s most challenging ski trail. Hills are abundant throughout the northern section of the loop. Access to views of Green Bay from high atop Sven’s Bluff may be obtained by those ready to take on the challenge.
Parking lot 3
- Skate Skiing (6.5 miles, difficult). Combined sections of the purple, blue and green loops are groomed for skating and striding.
Parking lot 5
- Yellow Loop (1 mile, easy). This is the easiest loop, geared for the novice skier. Skiers traverse very gentle terrain through hardwood forests and old fields.
- Orange Loop (3 miles, moderate). This is Peninsula’s most popular loop. Skiers with some experience will enjoy gliding down several hills.
- Red Loop (3.5 miles, difficult). The red loop is for more experienced skiers who like the challenge of hills. Skiing this is basically the entire orange loop plus an additional section that has a steep downhill.
- Green Loop (5.6 miles, difficult). This loop is ideal for intermediate level skiers who are looking for a longer tour. Skiers travel through remote areas of the park with a variety of forest types and across one large field just north of Middle Road. Watch out for some short hills between Highland and Middle Roads.
- Blue Loop (7 miles, difficult). This trail encompasses all the hills encountered on the red and green loops plus takes skiers through a long section of lesser used trail. Easy access may be made with the purple loop for longer tours.
Whitefish Dunes State Park
Green trail (1.8 miles)
Green Trail: travels along a forested old dune, through a lowland area which supports the growth of white pine and hemlock trees and back through a beech-maple forest.
Red trail (2.8 miles)
Red Trail: 2.8 miles long, but also has a shorter loop available. The trail takes hikers to "Old Baldy", the tallest dune in the park, which rises 93 feet above lake level. Old Baldy has an observation platform, for views of Lake Michigan and Clark Lake. A boardwalk and stairs lead to the top.
Yellow trail (4.2 miles)
Yellow Trail: branches off the Green trail at its farthest point. From the dune area, the Yellow trail goes through a cool, quiet, red pine plantation and then back through a wooded dune area.
Snowshoe trails(2.5 miles)
Black Trail: 2.5 miles long, but also has a shorter loop available. The trail takes hikers through a forest of mixed hardwoods and many exposed rocks. The dolomitic limestone bedrock near the surface is part of the Niagara Escarpment which underlies all of Door County and forms the rock ledges of nearby Cave Point
