Monte Cristo Lake

Monte Cristo Lake (Snohomish County) is in the North Cascades on the Mountain Loop Highway (FR 20), which runs from Granite Falls to Darrington. If you are heading toward Darrington, Monte Cristo Lake is located on the left side on the unpaved section of the highway; boggy Myrtle Lake is located on the right side of the highway. Monte Cristo Lake is down a short slope and adjacent to the South Fork Sauk River. The western portion of the lake is influenced by the river and flows faster than the more stagnant eastern portion of the lake.
