Winchester Mountain is said to have the greatest reward for least amount of effort in all the North Cascades. One of the last fire-lookouts in the region stands on the summit. Views from the summit of Winchester Mountain are beautiful and dramatic to say the least. Being one of the easiest hikes on Hwy 542, it gains only 1,300ft in 2.5 miles from Twin Lakes. NOTE: A high clearance vehicle is required to drive Twin Lakes Road beyond the Yellow Aster Butte trailhead. Otherwise park at the Yellow Aster Butte trailhead and hike 2 miles and 1,600ft to Twin Lakes (5,200ft). This will change the total mileage from 5 miles round-trip to 9 miles. GETTING THERE: From I-5 take exit 255 (Sunset/Mt Baker hwy) and drive east 31 miles to the town of Glacier Drive another 13.5 miles and take a left on forest service road 3065 (Twin Lakes Road) Drive 5 miles (stay left at all forks) park at the Yellow Aster Butte/Lake Tomyhoi trailhead From here high clearance vehicles may be able to drive beyond this point but it gets very rough. Park at Twin Lakes Trailhead.
