Mt. Thynne is a rounded, open mountain just 145 km from the Coquihalla Summit area. Because of its elevation (2256 m), location, and shape, snows clear off the access road and the summit ridge relatively early so we can do a summit hike in June. In 2020, the snows were slow to melt so we rescheduled our hike until the end of the month. The access road (16 km) from Brookmere (Lower McPhail, Thynne Mountain Road, Upper McPhail Road) was fine, though it is slow-going for some sections and high clearance near the top We parked at the snowmobile cabin and hiked up the double track. The summit of the mountain is 5.75 km south. The first part of the hike climbs 200m over 2.0 km, then the route goes up and down to the final hill.
From the open ridge, many of the Coquihalla Summit peaks were on show. A favorite hike is July Mountain, just 11 km west.
We hiked out and back on the same track (11.5 km total) on a fine day. There were some mosquitoes, but mostly in sheltered areas, away from the wind. We prefer to go to Thynne in the early season before the arrival of quads, 4×4’s, and motorcycles, but also when the higher alpine peaks are still snowed in.
This hike makes for a long day. We drove from Kamloops to Brookmere, then up the mountain road (we took one wrong turn and had to backtrack), hiked the mountain, and returned, an all-day adventure in remote country. We will be back next year in June.
