Spy Rock

This is a long, rambling route through wooded countryside, villages and lake country of the northwest corner of the Frontenac Arch Biosphere. Some parts of this loop wind over granite ridges of the Arch; some sections follow the old K&P railbed, converted by the County of Frontenac to a multi-use recreational trail. The towns of Sharbot Lake and Westport are great places to visit – lots to see and do, stay, and dine.

Start from the community centre just north of the causeway on the south edge of Sharbot Lake. Through the town, cycle north on Hwy 38 to turn right on Zealand Rd., and along it to Hwy 7. Turn east on Hwy. 7 (with paved shoulders), about a kilometre to the gravel-surfaced Fall River Rd. Turn east at an intersection with Armstrong Rd. also gravel, and after about two KM., turn south on Cross Rd.

Cycle south on the gravel Cross Rd. until it ends at the Crow Lake Rd. in the hamlet of Cross Lake, and go left, south, on the Crow Lake Rd. and then east all the way to County Rd. 36. Turn south, and on paved road to Westport.

You’ll probably be ready to refuel in Westport, and explore the scenic, historic village. From Westport, go west on Bedford Street, past the Catholic school and bear left/southwest on Salem Rd, which is County Rd. 12.

As you go from Leeds-Grenville to Frontenac County, Cty. Rd. 12 becomes Cty. Rd 8. Follow this, also called the Westport Rd., and about 400 metres past the county garage with the dome-shaped sand storage building, turn right/north on Buck Bay Rd., and in about 1.5 KM. turn west on White Lake Rd. However, at this leg of the loop you may want a bit of a break. About 300 metres up Buck Bay Rd. from the Westport Rd. is the Godfrey Sculpture Park, fantastic works by artist Stephen Duerst along paths on the shield terrain of the Frontenac Arch.

White Lake Rd. will intersect with Hwy. 38. Turn north on Hwy 38 for 100 metres, and onto K&P line, an old rail bed now a gravel recreational path. Continue north until just before the village of Tichborne, and turn off west on Fream St. at Tichborne. Now follow on Hwy. 38 north to Sharbot Lake. There’s a pleasant beach near the community centre – after this ride you may be ready for a swim.

Bike Suitability

This is a route for a hybrid and touring bikes – most of the route is paved, but sections have stone-chip surfaces and gravel surfaces, and lots of small hills.

Notes and Cautions

Limited sightlines in some areas, on narrower and winding roads. Highway 38 is well trafficked, but does have a white separating line at the road edge for a narrow paved shoulder.
