We like to walk, and a nice place to do so is around Ponkapoag Pond in the Blue Hills Reservation in Canton.  A trail of about 5 miles (8 kilometer) takes you all around the lake.

From Boston, take Route 128 South; take Exit 2 for Route 138 towards Stoughton;  go about a mile and turn left into the parking lot for the golf course and adjacent skating rink.

From the parking lot, follow the sugar maple avenue across the golf course. At the end of the avenue, continue straight.  Keep on the main path, with the lake on your left.  When you reach the AMC Camp, fork right downhill and continue straight.  Turn left onto a bridle path (follow the green dot).  Pass the YMCA Outdoor Center, and continue on the main path past the golf course back to the sugar maple avenue.
