Mount Barbour Trail serves as the primary route connecting Tenquille Lake to the summit of Mount Barbour, a peak situated in the Pemberton Valley of British Columbia.

The trail is most commonly accessed by hikers already camping at Tenquille Lake, making it a natural extension of an overnight trip to the area, though it can also be completed as a day hike from the Tenquille Lake trailhead.

The route begins by following the trail along the northern shore of Tenquille Lake to a junction at the lake's southeast end. The full out-and-back covers approximately 7. 8 miles and is rated difficult.

The trail falls within the Tenquille Lake–Hawint Recreation Site and the broader 8 Peaks Recreation Reserve trail network near Pemberton.
