One of the largest bodies of water in the Alpine Lakes Wilderness, Lake Dorothy is a perfect destination for families or backpackers looking for a short overnight trip. The north tip of the lake is just a 1.8-mile hike from the car, and the 2-mile shore offers a multitude of prime spots for playing, camping and fishing.

The trail starts by following the East Fork Miller River until it reaches Camp Robber Creek, where a bridge offers a pleasing view of tumbling water as it cascades down the rocks. After the bridge, the trail starts gaining elevation, and you will thank the volunteers who have built countless flights of stairs over this rocky section to make the ascent easier. Soon the lake comes into view, and a map of all the camping spots, day use areas, and toilets is posted at the junction to the first lake access.

Walking the full length of the lake will extend your trip to over 7 miles round trip, and you will be treated to wild blueberries in late summer, a multitude of picturesque little islands dotting the water, and views of Big Snow Mountains in the distance. If you would like to add even more mileage and elevation, follow the trail up the ridge to Bear and Deer Lakes or down the other side to Snoqualmie Lake. The further you venture from the trailhead, the more likely it is you will have a lake to yourself.
