Campsite 102 is a backcountry campsite on Bottle Lake within Kawartha Highlands Provincial Park in Ontario. Access is by canoe, and the lake is restricted to non-motorized craft and small fishing boats, keeping the surroundings quiet and undeveloped.

Bottle Lake is noted among canoe campers for its sandy beaches and proximity to waterfalls at the lake's north end. On calm evenings the water lies glassy and still, reflecting the surrounding trees and rocky shoreline.

A natural spring feeds the lake, and fishing is popular among visitors.
