The Heather Lake trail is located in the North Cascades' Mt. Baker-Snoqualmie National Forest, one of the most visited forests in the country. The trail itself goes over ancestral lands of the Stillaguamish people, and climbs along and across the hill, mostly along the Heather creek. The trail features old-growth forest, waterfalls, a few streams along, across, and on the trail, and finally a fairly nice lake in a quite spectacular setting.
A perfect hike featuring creeks, streams, waterfalls, all kinds of forests, from birch to brush to old growth, and the payoff is one of the most beautiful lakes out there.
There's plenty of ghost towns in Washington. Monte Cristo is one of them. But to get there, you have to hike 🤷♂️
