After you turn onto Hall's Road, keep your eyes on the fields and trees to either side. A bit further than halfway down there will be a small parking area on the left. There is a short trail to a viewing platform, where you can do some spotting. There are also feeders at the parking area that attact a variety of birds. Drive a little further down to a second parking area. There is another short trail leading to another viewing platform, again with some feeders around. The trail also splits off to the lakeshore where you can do some additional spotting.
Of course, if you going to Hall's Road, you can also park in the main parking lot for Lynde Shores just a little bit eastward. A bunch of trails head out from that lot.
