Lily Lake is a remote wilderness lake situated southwest of Merritt, British Columbia, in the Thompson-Shuswap region.

Accessed via rough gravel roads suitable only for 4×4 vehicles and trucks, the lake sits at roughly 3,800 feet elevation and draws visitors for fishing, canoeing, birdwatching, horseback riding, and wilderness camping.

A small forestry campground at the lake offers a handful of primitive sites, each with a picnic table and fire pit, along with pit toilets and a boat launch with a wooden pier for loading and unloading watercraft.

The surrounding area features a network of trails and gravel roads used by hikers, horseback riders, and mountain bikers, with some routes designated for specific user groups. Trails lead through grass valleys and up to hilltop viewpoints.
