Description From the Gray Access Trail, turn to the left for the Red Trail. Most of the time it travels through deciduous forest. Keep an eye out for a family of gray squirrels hopping through the White Oak and Red Maple trees.
As you start using the Gray Trail, you will go through some farm fields.
The Blue Trail then turns right and travels into an open crop field. A grassy path loops around the edge of the field, with the forest on one side. Through the trees you can view the Patuxent River. While on the trail look for wildlife such as groundhogs, song birds, and white tailed deer.
If you stay on the Gray Trail, you will cross Steer Horn Neck Road and begin on the White Trail. This trail is predominately a hardwood forest. You will find a variety of vegetation such as American Beech, Red Oak, Spice Bush, Mountain Laurel, and many types of grasses. At one point, Cuckold Creek can be viewed from the trail.
The Yellow Trail is also accessed by following the Gray Trail and part of the Red Trail. It then veers to the left off the Red Trail. Fields are home to mice, moles, groundhogs and rabbits. Forests are habitat for raccoons, fox, white tailed deer, and many birds. Several barns along the trails also provide birds with habitat including: owls, swallows and wrens.
