Sometimes, you just need an easy hike that leads to a beautiful destination, right? I’ve found the perfect spot near Snoqualmie Pass that’s definitely worth exploring. This trail offers everything from an easy hike to fantastic camping and even opportunities for boating.
Located close to Snoqualmie Pass, it’s easily accessible for those in the Seattle area. Family-friendly and perfect for anyone looking for a relaxed backpacking trip, this 2.9-mile trail features several lakeside campsites. With an elevation gain of 700 feet, it’s manageable for hikers of almost any skill level.
The Best Time to Visit Mirror Lake
This trail is best done during the summer and fall. In the winter, the forest roads close due to snow and are used as ski trails for snowmobiles. Since the trail is located at 3,500 feet, it’s also possible to hike during the spring and fall, provided there hasn’t been any significant snowfall or the snow has already melted. Be sure to check trail conditions before heading out, especially in the shoulder seasons.
Getting to the Mirror Lake Trailhead
From Interstate 90, take Exit 62 and then follow Forest Road 5480 for about 6 miles to reach the trailhead. The drive from the top of Snoqualmie Pass takes around 35 minutes, with about 25 minutes spent on a gravel road. The road is generally in good condition, though you should watch out for occasional potholes and sharp rocks. The trailhead has parking for roughly 10 cars, but on busy weekends, overflow parking typically spills onto the road.
Mirror Lake Trail Overview
From the parking area, the 2.9-mile trail with 700 feet of elevation gain begins on a rocky road filled with loose gravel and sharp rocks. Surprisingly, some vehicles attempt to drive up this road to reach the actual trailhead, though it’s not recommended. With the abundance of sharp rocks and potholes, there’s a high risk of damaging a tire. I found this part of the trail to be the most frustrating, especially since I was hauling up my Oru kayak to paddle in Mirror Lake.
The proper trail starts near the top of the road on the left side, transitioning from a road to an actual trail. It quickly enters an old-growth forest, offering beautiful views of distant mountains to your left. Along the way, you’ll cross a few small streams and pass a large fallen tree next to one of them. The trail climbs gradually up to Cottonwood Lake, a truly stunning spot. There are a couple of great campsites here, but if you’re looking for a swimmable lake, you’ll want to continue up to Mirror Lake.

From Cottonwood Lake, the trail heads up higher, passing through a relatively flat section along the lake before climbing higher towards Mirror Lake with a few small switchbacks. The trail eventually junctions with the Pacific Crest Trail (PCT) near the lake. Continuing along the the lake trail, it skirts around the entire lake.
Boating at Mirror Lake
If you’re up for the challenge, you’ll get to paddle on a beautiful lake surrounded by stunning mountain views. This spot offers a much more peaceful experience compared to other heavily trafficked locations, and you’ll likely have the entire lake to yourself. Just be sure to clean your paddleboard or kayak beforehand to avoid introducing any unwanted contaminants to this pristine lake.
Camping Options at Mirror and Cottonwood Lakes
Mirror Lake
Mirror Lake offers numerous campsites, with most located right by the water or very close to it. No camping permits are required, making it a hassle-free option. If you prefer hammock camping, there are plenty of trees to choose from. However, it’s essential to practice safe food storage by using a bear canister or hanging your food with a bear line, as bears likely frequent the area due to all the activity.
Cottonwood Lake
For a more private camping experience, there are a couple of secluded sites along the edges of Cottonwood Lake. While these spots are beautiful and quieter than those at Mirror Lake, the lake itself is shallow and muddy, which might not be ideal for swimming or paddling. However, if you’re looking for peace and solitude, Cottonwood Lake could be a great option.
My Essential Gear
