Brockville Railway Tunnel, Aquatarium

This loop takes you from the sandstone bedrock farmland of the east flanks of the Frontenac Arch, onto and through the much more ancient granite and forested landscape of the Arch itself. It’s an interesting chance to compare the building styles and farms on and off the Frontenac Arch.

This longer 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 yr 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, Cty. Rd. 46 joins Howe Rd and continues to the right. Instead, turn left over the bridge and then take an immediate right onto Seeley Rd. Seeley Rd runs generally west and almost dead flat with long straight stretches past the occasional farm and country residence, and lots of forest. Seeley Rd. becomes Cronk Woods Rd. and then Caintown Rd. From the turn onto Seeley Rd, you'll spin just under 10km to a T-stop at County Rd. 5.

Turn left onto County Rd. 5 and in about 1 KM turn right on Junetown Rd. where there is a quaint old church converted to a home. Junetown Rd. is very quiet and runs fairly straight and flat through farmland for about 4 km until you reach a T-stop. Turn left on what is still Junetown Rd.

The road winds along on top of a sandstone ridge, and through the trees to your right you're looking down at farmland on the rolling granite landscape, the big hump of Blue Mountain in the distance. Junetown Rd. ends at a T-stop at the bottom of a hill, at County Rd. 4. Turn right. This segment of Cty. Rd. 4 is also known as the Rockfield Rd. Passing through gently rolling farmland, you’ll come to a sign for Balleycanoe & Co., and of the ‘Open’ sign is up stop for a look into heritage architectural building materials, and creative art. Rockfield Rd. finally comes at an intersection with Blue Mountain Rd. Looking to the right, you'll see Blue Mountain just a few kilometers away.

Turn left/south on Blue Mountain Rd. exercising caution crossing the double rail line. Blue Mountain Rd. ends at T-stop at Mitchellville, at County Rd. 2.

Turn left to follow Cty. Rd. 2 to Escott, an eye on converging traffic as there are no paved shoulders as yet. At Escott, turn right onto the Escott Rd. Follow this tranquil, scenic road until it ends on the Thousand Islands Parkway, at Rockport. Slip into Rockport for an ice cream at the old boatworks River Rock Shoppe, or to fully refuel at the Cornwall Pub.

Continue on the return to Brockville on the Parkway cycling path to exit onto the Brockmere Cliffs Drive, just before the Parkway ends. This drive ends at Cty. Rd. 2. From there, continue to follow Cty. Rd. 2 all way the 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.
