This nature area in west Ann Arbor adjoins Lakewood Nature Area and can be reached from it, though its primary parking lot is off Wagner Road. It contains the only two natural lakes in Ann Arbor, First and Second Sister Lakes. A suggested nice hike, taken on this visit, starts in Lakewood Nature Area and heads west to get a good view of Second Sister Lake, shown in the accompanying photo snapped on the day my wife and I took that suggested hike.
