The Cliff Swallow Trail is a 3.7 mile loop trail. Cliff swallows nest in the limestone bluffs above Beaver Creek. Look for gourd-shaped mud nests in the rock out-croppings below the ridge. Other wildlife commonly seen along the trail include white-tailed deer, elk, and turkey. Along Beaver Creek, watch for blue herons, beaver, and water dippers. High above, turkey vultures are often seen riding the thermal drafts. Mountain lions, although rarely seen, also call this area home.
