To get there, take Highway 2 out to the Old Cascade Highway, located between milepost 45 and 46. Take the Old Cascade Highway out toward the Money Creek Campground, crossing the railroad tracks and continuing for a mile before turning right onto the Miller River Road (Forest Road #6410). Follow this road 9.5 miles until it ends. Confusingly, the road number changes to #6412 at roughly 4 miles – ignore this and continue onward to the trailhead. View Google Directions >>
The trail begins easily, following the East Fork Miller River for a little over a half-mile until Camp Robber Creek joins it. Take a moment at the bridge to enjoy the rushing water before plunging back into the old growth forest. The trail steepens once across the bridge, but stairs, elaborate boardwalks, and countless volunteer hours have tamed the once-rocky trail. Thousands of boots also keep the trail wide and extremely well maintained. At scarcely a mile-and-a-half a junction points you to the log-filled lake outlet and a view of the narrow lake with Big Snow Mountain in the distance. The trail then continues along the entire length of the lake and then over a ridge to Bear, Deer, and Snoqualmie Lakes, eventually connecting with the Snoqualmie Lake Trail #1002.

Short and rewarding, this hike is perfect for kids, families, and getting those non-hiking friends on the trail. While Dorothy Lake isn’t the largest lake in the Alpine Lakes Wilderness, it’s a contender, and it’s sure to impress. Small islands dot the lake surface and private nooks and coves abound, making it easy to find a good place for a break. For those looking for a longer day, continue around the far end of the lake and over the ridge to Deer, Bear, and Snoqualmie Lakes -- the extra effort putting you well beyond the reach of the crowds. Although rain and lingering snow kept us from continuing up the ridge to the other lakes, we’ll be back to explore them before long.


Unfortunately, we couldn’t find out the origin of the lake’s name, although we know it was christened sometime back in the 1800s. Most of the lore we could find centers around the previously described Dorothy Lake Highway Project that spurred the creation of the Alpine Lakes Wilderness. Today, all that remains of that dream is the Dorothy Lake Trail #1072, which still traces the proposed route.
