Also known as the four lake estravaganza, this hike is a nice sampler of the lakes accessible from the I-90 corridor just west of Snoqualmie Pass. The hike starts at the Talapus Lake trailhead where we hiked up to Talapus, around the east and north shores of Ollalie. From there we climbed to a pass and down around the east shore of Pratt Lake and on to our destination, Lower Tuscohatchie.
