The Little Douglas Lake Trail is a short backcountry route in British Columbia's Coquihalla Summit area, accessed via Exit 228 on the Coquihalla Highway and approximately 7 kilometres along the Britton Creek (Upper Coldwater) Forest Service Road.

The trailhead sits near the Zum Lake Recreation Site and is marked by a small sign. The round trip covers roughly 4 kilometres with about 95 metres of elevation gain, typically completed in around 1. 5 hours.

The route passes through tall timber, follows a rushing creek, and includes bog bridges and a creek crossing that lacks a formal bridge. The trail leads to Little Douglas Lake, a quiet alpine lake with a recreation site offering camping and pit toilets.
