For those searching for alpine vistas and a solid workout, Greider Lakes is just right. This trailhead is located in the Sultan Basin Watershed, within the Morning Star Natural Resources Conservation Area, managed by the Washington State Department of Natural Resources. This is a special designation to protect ecologically significant areas.
You'll drive right up to the shores of Spada Lake and traverse two flat miles to reach the old trailhead. Once you reach the old trailhead, the climb begins. You'll be huffin' and puffin' as you conquer 40 switchbacks, gaining over 1,000 feet in 1.5 miles. The trail is rough, too — be sure to have good boots or hiking poles to help with the ascent (and descent, too).
The trail evens out after the fortieth switchback and you'll be minutes away from the shores of Little Greider Lake. Big Greider Lake is less than a quarter mile beyond that. The edge of Big Greider Lake is an ideal lunch location, replete with a stunning view of exposed cliffs and jagged peaks across the lake.
