This short loop starts and ends in downtown Brockville at the parking lot on Water St. near to City Hall and looking over Tunnel Bay. It’s a leisurely rural road ramble where the eastern edge of the granite Frontenac Arch meets the primitive sandstone of the lower St. Lawrence plain.

The route out of town follows Water St., turn left on Perth St., right at the Brockville Yacht Club to Jessie, left on Ann to turn right on Hartley St. to where it ends at Rivers Ave., and finally left on King St., past St. Lawrence Park and then west on King St. to the edge of the city where King becomes Cty. Rd. 2.

Just past the Brockville Country Club, turn right onto Lyn Rd (Cty. Rd. 46) and cycle past one of four adjoining cemeteries (a few hundred metres along, on your left) that date back to Brockville's founding times. Follow Lyn Rd. as it goes under the CN Rail Toronto-Montreal main line and under Hwy 401, climbing two hair-pin turns up and over a granite ridge line with exposed rock cuts. This is the biggest climb on this route.

At the stop sign for Cty. Rd. 27, turn left to continue on Cty. Rd. 27/46. On your right, you'll pass Burnbrae Farms' headquarters - the largest egg producer in Canada - and one of its farms. A little further along, entering the village of Lyn, a school is on your right and a cenotaph on your left. Stopping at the cenotaph, you can look out and down to the south into the Lyn Valley.

At the main intersection in Lyn, going left into the village takes you to the Heritage Place Museum, once a blacksmith’s shop and insight into the village history. Go back to that intersection and turn left (bear right if you skipped the museum side trip) onto Cty. Rd. 46. You'll climb a nicely challenging short rise past the 135 year old United Church, and then out of the built-up town area and into rural countryside on the sandstone bedrock that lies atop the much older granite.

At the yield sign where Cty. Rd. 46 joins Howe Rd. and continues to the right, turn left instead over the bridge and then bear left to stay on Howe Rd. You're now heading south through flat farmland for just over two kilometers until you come to a T-stop at Yonge Mills Rd.

Turn right onto Yonge Mills/Cty. Rd. 27 which is also West Main St. coming out of Lyn. This is a long straight, gently undulating road. After passing Devils Door Rd. on your right (named for a door-like granite slab where in lore your team of horses would mysteriously unhitch themselves), and on the left you'll pass the Yonge Mills Stone Church, built in 1837.

Be careful crossing the double rail line just after the church - a busy route and not uncommon for one passing train to end with a second one coming the other way.

Continue on Yonge Mills Drive to the T-stop at Cty. Rd. 2. Turn left to cruise the Cty. Rd. 2 paved shoulder east to the Hwy 401 interchange, then continue on all the way back into Brockville, passing the cemeteries, the Country Club, and St. Lawrence Park before turning right onto Rivers Ave. and retracing your route to downtown
