The 27 kilometre road passes along the northern side of the Kingston Peninsula.

Skirting the southern shore of Belleisle Bay, the route passes through Keirsteadville, Long Point and Erbs Cove, before terminating at Kingston at an intersection with Route 845.

Just north of Erbs Cove, there is a cable ferry across Bellisle Bay.

Much of the route passes through a narrow band of low lying agricultural land with forested hills rising in the background.

This is a popular summer residential area and there is a small marina on the bay.
