Simply spectacular! One of the finest hikes on the face of the planet, the trail to Hidden Lake Peaks grants continuous sensory overload. Sprawling meadows bursting with wildflowers, granite slabs and boulders laced with heather, glistening snowfields birthing tumbling waters, alpine nooks providing refuge to ptarmigans and pipits, a historical fire lookout, and views-stunning, mouth-gaping views of a serrated skyline of snow, ice, and rock. It doesn't get any better than this.

After starting in a clear-cut predating common sense, the trail soon enters unmolested forest where it begins to climb steeply. At about 1 mile leave the forested canopy be-hind for an avalanche chute filled with alder. Cross East Fork Sibley Creek and recommence climbing. While you're traversing the steep side slope that's often brushy and overgrown, showy flowers give some consolation as you slog. Biting flies, however, may diminish the blossom bonus.

At 2.5 miles the trail recrosses the creek (elev. 5200 ft) and begins angling south. Stop to admire Mount Baker hovering in the western sky. Now across heather slopes punctuated with shiny granite slabs funneling cascading snowmelt, enjoy increasing views and an alpine wonderland intensifying in beauty.

At 3 miles a potential hazard may exist. Early season, or some years all summer, a treacherously steep snow gully may be present. Extremely dangerous to cross without ice ax and appropriate skills, it may be necessary to call it quits, taking solace in prudence and a decent hike even to this point. If the coast is clear, proceed, enjoying heather meadows, glacier lily fields, snowfields dyed red (thanks to an algae), unhindered Cascade mountain views west and south, and territorial views of Hidden Lake Peaks to the east.

At 4.2 miles attain a 6600-foot saddle (and the North Cascades National Park boundary) between the 7088-foot true summit of Hidden Lake Peaks (to the left and a fairly easy scramble) and the 6890-foot knoll with the lookout (to the right). Hidden Lake is just below, a glorious backcountry body of water, its azure waters shimmering in the sun. It's a rough-and-tumble drop of 800 feet through talus to reach it. Instead, enjoy its beauty from above and the framing backdrop of impressive North Cascades summits- Eldorado, Forbidden, and Boston among them.

To reach the lookout, follow the trail right for 0.3 mile, climbing 300 feet over ledge and rock and possibly snow (use caution). Wow! Drink in views from Rainier to Baker and every peak, valley, and ridge between. Take time to appreciate the lookout too. Built in 1931, it was restored by Fred T. Darvill of the Skagit Alpine Club back in 1961. A tireless advocate for the North Cascades National Park, Darvill, who passed away in 2007, was the writer of an early guidebook that introduced me to this region back in 1985.
Driving Directions:

From Marblemount head east on the Cascade River Road for 9.7 miles, turning left onto Forest Road 1540 (Sibley Creek Road), 1.5 miles beyond the Marble Creek Campground entrance. Follow rough-at-times FR 1540 for 4.7 miles to its terminus and the trailhead (elev. 3600 ft).

This was the most beautiful hike that I've done this season. I think my passenger car would have had trouble making it up Road 1540. The first mile was clear of all fallen trees but once you make it to the open area about a mile it, the trail narrows and at points the dirt was eroding away down the slope. The trail was slightly overgrown but not hard to follow. Consistent snow started at 5000' according to the handheld GPS. From the last trail report it must be new snowfall. I made it to the top fairly easily in just hiking boots but it would have been easier with my poles and microspikes. When the snow trail splits follow it to the left to the back side of the mountain to make it to the lookout. It took about 2 1/2 hr up and 1 1/2 down. Overall, a awesome hike to do before it gets completely snowed in.

This was a very pretty hike. The road is easily passable to passenger cars. The first mile of the hike has been cleared of downed trees and trail maintenance has been done. There are a couple of small snow patches and one large patch left, but all are easily crossed and no ice axe is needed. There were still a few wildflowers in the meadow part of the trail. It was a gorgeous hike with great views of the surrounding peaks.

First time I did this this hike, and it will not be the last. The trial was in good shape as it has been cleared of blown over trees. The first mile of so the trail was in good shape as there are some boardwalks you hike on. Crossing Sibley Creak is a little dicey as you have to rock hop your way across. From here on, the hike offers grand views of the valleys and the Cascade Peaks surrounding you. You have to keep moving while you are traversing the steep slops or the bugs will eat you alive. The trail is overgrown through here, but is always in sight. The first sign of snow was below the saddle where you had to just follow the snow fields to the top of the saddle. Once I reached the top of the saddle, Hidden Lake was in view, and what a view!!. From this point, I went to the right and found the trail to the lookout. You have to do some scrambling on large rocks for the final 300 feet to the lookout. I wish I could have spent the night at the lookout, but I will next time.

The first half mile of the trail goes through a forest and there are lots of downed trees. Sometimes, especially going up, the detours around the fallen trees are hard to find. Lots of crawling through dense brush/branches in the forest part. Once the trail leaves the forest it climbs through dense vegetation for the next couple miles. That part was the hardest because the trail is exposed to the sun but because of the tall plants/bushes there's no breeze. It was really hot and humid hiking up that dusty section, the trail is a bit steep and the bugs there were just awful! Once the trail gets higher on the ridge there's more wind, less bugs, and more views. The rest of the trail climbs up through white granite fields, very beautiful. There are few snowfields, some are a bit steep, if you are not used to the snow/your shoes don't have much traction I recommend hiking poles. Once you get to the point where you see the Hidden Lake the trail goes up to the Lookout. We didn't make it all the way to the lookout because the trail is confusing, exposed, and we think it was actually covered in snow. Oh well

Wonderful hike, definitely one of the harder day hikes but well worth it!
