Why Hike Spencer Basin
Beautiful Spencer Basin is a little known gem to the northwest of the Highland Mary Lakes. An old mining road climbs into the heart of the basin where trails and routes lead to the remnants of a mine and two passes. The solitude and untrammeled condition of the basin adds to the allure.
There are actually three destinations in this large basin that can be combined to create hikes of varying lengths and difficulties. Experienced hikers adept at scrambling will find additional areas to explore.
The trailhead is best reached by a high clearance vehicle. Low clearance passenger vehicles will need to park at the mine ruins near the end of County Road 4 and walk to the trailhead, adding 1.6 miles round-trip to the total distance.
