Raptors are normally secretive birds, but during their autumn migration, hundreds, sometimes thousands of hawks pass Hawk Mountain on a single day if the weather is right," she says. Late August and early September are optimal times to see bald eagles, ospreys and American kestrels, as well as migrating hummingbirds and monarch butterflies.   Binoculars are a must, and are available for rental in the Visitor Center . The closest lookout (where helpful guides are stationed) is just 100 yards from the Visitor Center along a graded trail. North Lookout is a one-mile trek along the rocky but scenic Lookout Trail, a 300-foot elevation climb. Daypacks to carry gear and flexible-sole shoes with some traction are recommended.

The Sanctuary is operated by Hawk Mountain Sanctuary Association, a non-profit organization devoted to the conservation of birds of prey. Hawk Mountain is famous as the world's first refuge for predatory birds and is recognized internationally as a center for raptor conservation.

The 2,600-acre Sanctuary includes a Visitor Center with wildlife viewing areas, Wings of Wonder gallery, interactive exhibits and bookstore, a Native Plant Garden , an eight-mile trail system, Ice-age boulder field and half a dozen scenic overlooks.   Trail fees cost $5 adults, $4 seniors and $3 children six to 12. Fees increase to $7 for adults and seniors on Saturdays, Sundays and holidays from Labor Day through November. Admission is free for one year with the purchase of a Mountain Membership, beginning at $35 or $40 for an entire family.

Hawk Mountain Sanctuary is located just off Route 895, seven miles north of the Rte 61/Hamburg and Cabelas intersection. For more information, directions, or details on upcoming events, visit www.hawkmountain.org, or call the Info Line at 610-756-6000.
