Copper Glance Lake Trail is a 6 mile lightly trafficked out and back trail located near Winthrop, WA that features a lake and is rated as difficult. The trail is primarily used for hiking and is accessible from June until October.
Follow the North Cascades Highway (State Route 20) east to Winthrop. Just before entering the town center, turn left onto West Chewuch River Road. In 6.75 miles reach the junction with the East Chewuch River Road (which comes from Winthrop) and continue north, now on Forest Road 51. Follow this paved road for 2.6 miles, turning left at Eightmile Ranch onto FR 5130 (signed Billy Goat 17). Continue for 12.4 miles (the pavement ends in 5 miles) to the trailhead at a gated old jeep road (elev. 3800 ft).
Great views! Went in late August on a weekday and didn't encounter anyone else on the trail.
Steady & steep, but worth the trip!
October was the perfect time of year for this hike. Golden larch trees and jagged peaks surrounding a green colored lake. Much of the road to the trail head is paved, and the dirt road section was in perfect condition - not a single pothole. I only ran into 6 other people on the trail. Beautiful hike overall.
