Twin Lake, Upper

Upper and Lower Twin Lakes (Whatcom County) are located off the Mt. Baker Hwy at the end of FR 3065. Reaching them requires a treacherous drive up a seven-mile stretch of steep, narrow, unpaved road with hairpin switchbacks and vertigo-inducing shoulders. High clearance four-wheel drive vehicles are recommended for the entire stretch. Many visitors park at the Yellow Aster Butte Trailhead and hike the remaining three miles. At the top are two glacial tarns, separated by an artificial dike and surrounded by towering peaks.
