The page profiles the Heather Lake in Snohomish County, Washington; another lake of the same name is located in Chelan County's Central Cascades.
Over its short distance, Heather Lake’s trail traverses distinct landscapes, contrasting stark, stump-filled new forest with lush, old-growth woodland before rounding a verdant alpine lake set amid rough-hewn peaks. Deep shadows enclose the stripling forest below, but sunlight increases among the well-spaced ancient giants at higher elevation, opening entirely along much of the lakeshore where summer wildflowers proliferate.
As it climbs, the trail becomes increasingly rugged, often worn to rocks and roots that can be treacherous to navigate, especially when wet. Be prepared with traction gear of choice. Given its short distance and relative ease of access, the trail is a popular destination. Those seeking more solitude may wish to visit on a less-frequented weekday. Aside from the occasional chatter of other hikers, no sounds of civilization mar the alpine tranquility of birdsong and tumbling rills wafting across the stony lake basin.
