TrailAgnes Gorge Trail
5 miles, 500ft gain. Muddy spring; wildflowers mid-summer. Easy-to-moderate ramble to a 200ft cascade.

This is a 4.2-mile moderate hike with a punishing 1,500-foot elevation gain that climbs relentlessly through lodgepole pine, hemlock, and fir forest to a pristine alpine lake. The payoff is a rare ecosystem of plants growing on floating logs in the water. It's uncrowded—real solitude in the North Cascades. But don't underestimate the elevation gain; it demands respect, fitness, and strict hydration discipline.
Moderate
A quiet alpine lake in subalpine forest with a unique ecosystem of plants growing on floating logs. The lake is ringed by steep forest, offering real solitude and rare botanical interest.
• Start early—afternoon thunderstorms are common in July-August. Be off the trail by 2 PM. • Descent is hardest on knees; use trekking poles and zig-zag to reduce impact. • The trail is well-established and easy to follow; still bring a map for context and navigation. • The floating-log plant ecosystem is the highlight; take time to examine it at the lake.
Late May through late September
Suitable for kids ages 10+ with hiking experience and good fitness. Younger children may struggle with elevation gain and descent impact on knees. Supervise closely on steep sections.
Hikers consistently praise the moderate difficulty and uncrowded setting. The elevation gain is relentless but manageable for conditioned hikers. Many note the unique floating-log ecosystem and real solitude as the main rewards.
No permit required for day hikes.
Not required. Parking is first-come, first-served at the trailhead.
Bears are present; maintain 100-yard distance and make noise. Elevation gain is relentless—expect leg burn and fatigue on descent. Wet roots and mud are slippery, especially in spring. Stream crossings may have high water in June. Afternoon thunderstorms are common in July-August; start early and be off the peak by 2 PM.
Rooty and steep in sections. 1,500 feet of elevation gain is sustained. Not wheelchair accessible; not suitable for young children or those with mobility limitations.

Not ideal. The 1,500 ft elevation gain is relentless. You need moderate fitness and experience on steep terrain. If you can hike Half Dome or similar, you can do this.
Yes. Keep 100 yards away and make noise constantly. Store food in bear canisters. Bear encounters are rare but taken seriously; follow the rules.
No, it's uncrowded—one of the quietest trails in the park. Summer weekends see more traffic, but nothing like Diablo Lake Trail.
No. Day hikes are permit-free. Just show up and go, but tell someone your itinerary.
Yes, very well-marked and easy to follow. Still bring a map; don't rely on memory or your phone.
Be off the trail by 4 PM to avoid hiking in darkness. In summer, afternoon thunderstorms roll in around 2–3 PM; be off the exposed ridge by then.
Strongly recommended. The descent is knee-pounding; poles reduce impact and save your joints. They also help on steep ascent.
