As far as riding the don goes, you can park at Pottery Rd, & Bayview. There is a dirt patch on the north side of Pottery Rd. just east of Bayview. There is a coupple of trails starting off from that point north, follow the lower trail north, you will cross a driveway into the sewage plant, carry on north from there, its a great trail, you can go right up to Taylor Creek Park from there, Those are probobly the busiest trails in the Don, Have fun, and Keep the Rubber Side Down.
