#26.Birding Bayfield’s Big Ravine (FT-4) 6:45 am – 11:00 am The 250-acre Big Ravine Preserve is a natural gem in the heart of Bayfield defined by 1.5 miles of a deep ravine and the stream that runs through it. We will follow the Gil Larsen trail a half mile along the stream with views of the Old Iron Bridge, waterfalls, and towering tree covered slopes. Then we’ll climb the Pine Bluff spur trail to the ravine's East Rim and hike along the rim back to the trailhead, along the way looking for warblers, vireos, thrushes, and other forest birds. Be prepared for four stream crossings and a gradual yet steep climb to the rim of the ravine. Optional: Meet at trailhead parking lot in Bayfield on Washington Ave. opposite Broad St. by 7:15 am. Additional Cost: Parking $10/car (or free on adjacent streets)
