I hiked to Hidden Lake Lookout in one day, watched the sunset, and then hiked down in the dark. It was one of the best hikes I did all summer! You can hike this trail in a single day or make it an overnight trip. The trail gives you a lot of variety, with meadows full of wildflowers, giant granite rocks, and snowfields with small waterfalls. I only had a few days in the North Cascades, but this hike made me want to come back as soon as possible.
If you’re visiting the Pacific Northwest, hiking the Hidden Lake Lookout trail should definitely be on your list! This guide will help you plan an amazing day hike in the North Cascades.
Why Hidden Lake Lookout Trail is the Best
The trail is often considered one of the most scenic hikes in the North Cascades, and for good reason. The trail takes you on an exciting journey! It starts in thick, green forests, then opens up to alpine meadows full of colorful wildflowers. At the end, you’ll reach a historic fire lookout that gives you incredible views of the entire North Cascades mountain range.
Best Time to Hike
Hiking in North Cascades National Park depends a lot on the weather, so it’s important to check trail conditions before you go. The best time to hike to Hidden Lake Lookout is usually from mid-summer to October, depending on when the snow melts and if early snow comes. Watch out for mosquitos during the summer because they can be really bad. I hiked there in late August on a weekday, and I had clear skies, hardly any bugs, and saw only a few people on the trail.
Make sure to check the North Cascades National Park website for updates, or visit the nearest ranger station in Marblemount before you head to the trail.

Special Concerns for Hidden Lake Lookout
Backcountry Camping
If you plan to camp at Hidden Lake, you’ll need to secure a backcountry camping permit. There are two popular camping spots: near the lake itself or at the summit by the fire lookout. Camping at Hidden Lake Lookout offers a unique overnight experience, but be prepared for cold weather at higher elevations, especially at night.
Detailed Trail Description
The trail begins in a thick forest and slowly climbs up through a series of switchbacks, making the hike easier as you gain elevation. After the first climb, the trail leads into beautiful meadows filled with wildflowers in the summer, with amazing views of the nearby mountains. As you hike higher, the trail gets steeper and more challenging, and near the top, you’ll need to do some rock scrambling to reach the summit. The final push to the Hidden Lake fire lookout involves navigating large boulders.
The last section of the trail is the most challenging but incredibly rewarding. From the Hidden Lake fire lookout, hikers can see distant peaks, including Mt. Baker, Glacier Peak, and Eldorado Peak. On a clear day, the views stretch for miles, and the lookout itself adds a historic touch to your adventure.
Before You Go
To ensure a safe and enjoyable hike, consider the following tips:
- Check Trail Conditions: Look up current trail reports to see if there’s snow on the trail or other hazards.
- Pack Essentials: Bring plenty of water, as there are limited reliable water sources. A map, compass, and GPS are also essential for navigation.
- Hiking Gear: Sturdy boots, trekking poles, and layers for warmth are key for this hike, especially given the trail’s elevation gain and rocky terrain.
- Weather Forecast: The lookout is exposed, so be prepared for wind and sudden weather changes.
Activities and Scenic Highlights at Hidden Lake Lookout
Views and Photography
From the summit, you’ll have one of the best panoramic views in the North Cascades. Whether you’re catching the Hidden Lake Lookout sunrise or staying for sunset views, the changing light casts a magical glow on the surrounding peaks. The lookout and surrounding rocky ridges provide some of the best photo spots for nature lovers and photographers.
Wildlife and Wildflowers
The Hidden Lake Lookout trail is known for its seasonal wildflowers. Depending on when you visit, you’ll see blooms like lupine, Indian paintbrush, and mountain heather. Wildlife such as marmots, mountain goats, and pikas are often spotted along the trail, making this an excellent hike for wildlife viewing.
Hidden Lake Lookout Camping
If you’re planning an overnight stay, be sure to secure your camping permit. The trail itself is available for overnight use on a first-come, first-served basis, and there are tent sites near the lake. Always remember to pack out everything you bring and practice Leave No Trace principles.
How to Get to Hidden Lake Lookout
The Hidden Lake Lookout trailhead is about 30 minutes east of a small town called Marblemount and around 2.5 hours from Seattle, Washington. The trail starts in the Snoqualmie National Forest and then enters North Cascades National Park. You don’t need a parking pass at the trailhead.
To get there, drive on State Route 20 to mile marker 106, which is Marblemount. Cross the Skagit River on a big steel bridge to reach Cascade River Road. Follow this road for 10 miles and turn left onto Sibley Creek Road (also called FS 1540). You’ll see signs for the Hidden Lake Trail. Drive carefully up the steep and rocky road for 4.5 miles until you reach the trailhead. Make sure to check road conditions before you go, as this road often has washouts. I drove my Sprinter Van up there, but it was tricky with some big potholes and tough spots.
Is Hidden Lake Lookout Dog-Friendly?
While dogs are allowed on the Hidden Lake Lookout trail, the steep and rocky sections near the top may not be suitable for all pets. If you’re bringing your dog, ensure they are fit enough for the trail’s challenges, and always clean up after your pet to help preserve the environment.
