Rock Lake Trail

Trail Overview

Rock Lake Trail (Trail #1587) is a demanding but rewarding alpine hike in the Okanogan-Wenatchee National Forest, located just east of Stevens Pass in Washington’s Central Cascades. This steep, relentless trail climbs from Highway 2 to the summit of Rock Mountain, one of three prominent peaks along Nason Ridge, offering stunning panoramic views of the Cascade Range.

The trail is known for its punishing ascent—gaining over 4,000 feet in less than 4.5 miles—making it a fitness challenge and a test of determination. Hikers endure approximately 90 switchbacks on exposed slopes before reaching alpine meadows, the junction with Nason Ridge Trail, and ultimately the former fire lookout site atop Rock Mountain. Along the way, you’ll enjoy expansive views of the Skykomish River Valley, Chiwaukum Mountains, and on clear days, peaks including Mount Rainier, Glacier Peak, and Mount Baker.

Difficulty Assessment

Rock Lake Trail is rated strenuous due to significant factors that challenge even experienced hikers. The trail gains approximately 2,250 feet in just the first 2 miles, with steep, sustained climbing throughout. Over 90 tight switchbacks zigzag up exposed slopes with little shade, making summer heat a serious consideration. The trail surface alternates between dirt, grass, and rock, with some sections narrow and eroded.

Despite the difficulty, the trail is well-defined and doesn’t require technical skills or scrambling except in snow conditions. It’s an excellent conditioning hike for those preparing for longer alpine adventures, but first-time hikers should choose an easier trail to build experience and fitness.

What Makes This Trail Special

Rock Lake Trail offers an unusual combination of accessibility and wilderness experience. Located just off Highway 2, the trailhead is easy to reach, yet the trail itself feels remote and less crowded than many nearby Cascade hikes. The southern exposure provides an earlier snow-free season (often by late June in average snow years) and stunning views throughout the ascent, rather than hiking through dense forest to reach viewpoints.

The payoff at the summit is exceptional: Mount Howard and Mount Mastiff dominate the view along Nason Ridge, while the horizon reveals Glacier Peak, Sloan Peak, Pugh Mountain, the Monte Cristo massif, and distant views of Mount Rainier and Mount Baker. Below, Rock Lake sits in its glacially-carved cirque, often holding snow well into summer. The geological features—including striated granite formations created by ancient fault movement—add educational interest to the scenic beauty.

Best Time to Hike

The optimal hiking window for Rock Lake Trail runs from July through October, with conditions varying by season and snowpack:

Early Season (June-early July): Snow may linger on upper sections and north-facing slopes. Ice axe and microspikes recommended, especially in high snow years. Lower switchbacks typically snow-free by mid-June. Check trail reports before attempting.

Mid-Season (mid-July through August): Peak hiking season with snow-free trails, wildflowers in alpine meadows, and generally stable weather. Temperatures can be hot on exposed lower switchbacks (80-90°F possible). Afternoon thunderstorms occasionally occur. Most crowded period.

Late Season (September-October): Excellent conditions with cooler temperatures making the exposed climb more comfortable. Fall foliage (vine maple, slide alder) provides brilliant orange and crimson colors. Fewer crowds. Days shorter with less daylight. First significant storms typically arrive in October.

The trail’s southern exposure means it melts out 2-4 weeks earlier than north-facing alternatives and remains hikeable later into fall. This makes it particularly valuable for shoulder season hiking.

Detailed Route Guide

Trailhead to First Viewpoint (0.0 – 1.0 miles)

The trail begins at approximately 2,675 feet elevation on a rough service road that provides access to powerlines crossing Stevens Pass. The setting starts unassuming, with the hum of Highway 2 traffic audible below and powerline infrastructure visible. Don’t be discouraged—this quickly changes.

After one-third of a mile, the decommissioned road makes a sharp left turn where you’ll see a sign for Rock Mountain Lookout. The trail soon transitions from road to footpath and begins its ascent in earnest. Within the first mile, you’ll encounter several wide switchbacks that offer your first views back down to the trailhead and Highway 2. Vine maple, slide alder, salal, and ferns line the trail, providing vibrant fall colors when hiking in September-October.

The trail narrows after about 0.5 miles and begins the steep, exposed ascent characteristic of this route. Ponderosa pines with distinctive puzzle-like bark become common, indicating the drier east-side Cascade environment.

The Switchback Marathon (1.0 – 2.1 miles)

This section represents the trail’s most challenging segment: approximately 2,250 feet of elevation gain in just over 2 miles, accomplished via roughly 90 switchbacks zigzagging up the steep slopes. The trail runs parallel to (but never reaches) Schilling Creek, which flows from Rock Lake in the distance.

Despite the physical demand, the exposure provides continuous views as compensation. Peaks visible during the ascent include Arrowhead Mountain, Big Chief Mountain, Jim Hill Mountain, and the Chiwaukum Mountains. The Skykomish River Valley spreads below, and you can watch vehicles traveling Highway 2 along the southern section of the Cascade Loop.

At around 4,000 feet elevation, tree cover increases slightly, providing welcome shade. This is an ideal spot to rest, refuel with water and snacks, and prepare for the remaining climb. Maples and birch trees add to the forest diversity here.

Ridge Approach (2.1 – 3.2 miles)

At approximately 5,000 feet and 2.1 miles, the trail finally grants respite from the zigzag slog. The grade moderates as the trail begins a contoured angle away from the Stevens Pass corridor, delving deeper into the Okanogan-Wenatchee National Forest along a rib extending from Nason Ridge. This section gains another 700 feet but feels significantly easier after the relentless switchbacks.

At 2.6 miles, you’ll encounter a warning sign for an artillery impact area. Stay on the established trail here—the terrain drops off sharply to Schilling Creek in the swale below, and straying off-trail poses safety concerns. As long as you remain on the trail, there’s no danger.

As you approach 2.8 miles and climb through fir and hemlock forest, the landscape transitions to heather-carpeted meadows interwoven with ground blueberry. Views open up to show the ridgeline ahead, though the actual summit of Rock Mountain remains hidden. A prominent knob on the ridge visible to your left is not your destination—there’s still 1,200 vertical feet to gain.

Nason Ridge Trail Junction (3.2 miles)

At 3.2 miles and approximately 6,000 feet elevation, you reach the junction with the Nason Ridge Trail (#1583), a significant milestone. Turning right (east) leads toward Rock Lake itself and continues along Nason Ridge. Your route to Rock Mountain’s summit turns left (west).

Shortly after turning left, you’ll reach a viewpoint overlooking Rock Lake, sitting in its glacially-eroded cirque below the steep slopes of Nason Ridge. The alpine lake often retains snowfields well into fall. Be sure to stay on durable surfaces (rock, established trail) when viewing the lake to protect fragile alpine vegetation. This viewpoint sits at approximately 3.5 miles from the trailhead.

Summit Push (3.2 – 4.3 miles)

From the Nason Ridge junction, the trail traverses through alpine meadows dotted with striated white granite formations. The terrain includes some rutted sections where water drainage has carved channels down the slope. Several nice rest spots exist here under gnarled alpine trees on rises next to the trail.

About 0.5 miles beyond the junction, you’ll reach a ridgeline and begin traversing toward the summit. At approximately 3.7 miles, the trail intersects with the alternate route coming up from Snowy Creek Trail (#1531)—the longer, more gradual northern approach to Rock Mountain. The ridge trail here can be rocky and uneven, requiring careful footing to avoid ankle twists.

The final 0.25 miles leads to the stone foundation of the old fire lookout at 6,852 feet. The lookout structure is gone, but the summit platform provides outstanding 360-degree views of the Central Cascades.

Summit Views & Return

From Rock Mountain’s summit, the panorama is exceptional: Mount Howard (7,063 feet) and Mount Mastiff continue eastward along Nason Ridge; Glacier Peak, the Monte Cristo massif, Sloan Peak, Bedal Peak, and Pugh Mountain stand out to the north; the Chiwaukum Mountains and Mount Stuart dominate the south; Mount Rainier and Mount Baker appear on clear days; and countless other Cascade peaks fill the horizon. Directly below, Rock Lake twinkles in its cirque. Mountain goats and marmots are sometimes spotted in the alpine areas.

Take time on the summit to examine the intricate designs in the plutonic igneous rock formations—swirls and lines tell the geological story of ancient fault movement and the forces that shaped these mountains.

The return follows the same route, with the steep switchbacks requiring careful footing and providing significant impact on knees during the 4,150-foot descent. Trekking poles are highly valuable for the downhill.

Directions to Trailhead

From Seattle/Western Washington: Take I-90 east or US Highway 2 through Monroe and Sultan toward Stevens Pass. Continue on US Highway 2 for 65 miles to Stevens Pass, then continue east for another 8.5 miles. The trailhead turnoff is just after milepost 73, approximately 0.4 miles east of the Washington Department of Transportation maintenance buildings. Look for a brown trail sign on the left (north) side of the highway.

From Leavenworth/Eastern Washington: Take US Highway 2 west for approximately 26-27 miles from Leavenworth. The trailhead turnoff will be on your right (north), just past the power lines that cross the highway, approximately 0.4 miles east of WSDOT buildings.

At Trailhead: Turn left onto an inconspicuous, rutted dirt road leading almost immediately (about 75 feet) to the trailhead parking area. The road is short but rough—high clearance helpful but not required. Parking accommodates approximately 4 cars. No privy facilities available.

GPS Coordinates: 47.7757, -120.9581 (WGS84)

Nearest Services: Leavenworth (26 miles east) offers full services including gas, groceries, restaurants, and lodging. Stevens Pass Ski Area (8.5 miles west) has limited services when open.

Weather & Seasonal Considerations

Central Cascade weather can change rapidly, especially at higher elevations. The trail’s southern exposure provides both advantages and challenges:

Spring/Early Summer (May-June): Snow persists on upper trail sections, particularly above 5,000 feet and on north-facing slopes. Rock Lake basin typically holds snow into late June or early July. Lower switchbacks may be snow-free by late May in light snow years. Trail conditions vary significantly year-to-year based on winter snowpack.

Summer (July-August): Generally snow-free with warm to hot temperatures. Exposed lower switchbacks can reach 80-100°F on sunny days—start early! Alpine sections remain comfortable (60-75°F). Afternoon thunderstorms possible, especially in August. Morning starts recommended to avoid heat and lightning.

Fall (September-October): Cooler temperatures (50-70°F) make the exposed climb more pleasant. Outstanding fall foliage colors. Generally stable weather but first major storms arrive in October. Shorter days require earlier starts. First snow possible in October at summit.

Weather Preparation: Conditions at 6,800-foot summit differ significantly from trailhead. Bring layers for changing conditions, including wind protection. Check NOAA weather forecast before hiking. Be prepared to turn around if threatening weather develops.

Water & Food

Camping Information

While most hikers complete Rock Lake Trail as a day hike, overnight camping is possible and allows more time to explore the Nason Ridge area or summit Rock Mountain at sunrise.

Camping Locations: Established campsites exist along Nason Ridge Trail near Rock Lake and at the lake basin itself (requires off-trail travel of approximately 0.3-0.5 miles from the trail junction). Camping also possible along Nason Ridge Trail heading east toward Merritt Lake and Lost Lake.

Camp at Least 200 Feet From: Water sources, trails, and Rock Lake itself to minimize impact and protect water quality.

Bear Precautions: Black bears present in area. Hang food properly or use bear canister. Do not leave food unattended at camp.

Leave No Trace: Use established campsites when available. If dispersed camping, choose durable surfaces (rock, bare ground). Pack out all trash. Use catholes 6-8 inches deep and 200+ feet from water sources.

Safety & Hazards

Primary Hazards

Wildlife

Black Bears: Present throughout the Okanogan-Wenatchee National Forest. Store food properly when camping. If encountered, make noise, appear large, back away slowly, do not run. Bear spray can be carried for additional safety. Most bears avoid humans.

Mountain Goats: Sometimes spotted on Rock Mountain summit and surrounding alpine areas. Maintain distance (minimum 50 yards). Never approach for photos. Goats habituated to humans can become aggressive when seeking salt/food.

Marmots & Pikas: Common in alpine areas. Cute but leave gear unattended and marmots may chew straps/packs seeking salt. Keep gear secured.

Rattlesnakes: Possible at lower elevations, particularly on hot days. Rare above 4,000 feet. Watch where you place hands and feet. Give snakes space if encountered.

Getting Help

Cell phone service is generally poor to non-existent on the trail, though some coverage may exist at the summit ridge or near Highway 2. Do not count on cell service for emergencies.

Emergency Contacts:

• Emergency: 911 (if signal available)
• Chelan County Sheriff: (509) 667-6571
• Wenatchee River Ranger District: (509) 548-2550

Before You Hike: Inform someone reliable of your hiking plans, including expected return time. Carry basic first aid supplies. Consider personal locator beacon (PLB) or satellite messenger for remote area communication.

Gear & What to Bring

Essential Gear Checklist

Clothing & Layers

Lower Body: Hiking pants or shorts (quick-dry synthetic or wool preferred), underwear, hiking socks (synthetic or wool, no cotton), sturdy hiking boots or trail runners (broken in!), consider bringing lightweight long pants for summit even on hot days

Upper Body: Moisture-wicking base layer (synthetic or merino wool—no cotton), optional light insulating layer (light fleece or synthetic), warm insulating layer for summit (fleece jacket or lightweight puffy), wind/rain jacket (essential—conditions change rapidly at elevation)

Accessories: Hat or cap for sun protection, warm beanie for summit, lightweight gloves (surprisingly valuable even in summer), bandana or neck gaiter

Recommended Gear

Trekking Poles: Highly recommended, especially for the knee-punishing descent. Reduce impact on joints, improve stability, helpful for balance on rocky sections.

Gaiters: Useful to keep dirt and debris out of boots, especially valuable if early season snow present.

Camera: The views are exceptional—bring a camera or ensure phone is charged.

Binoculars: Optional but excellent for identifying distant peaks and spotting wildlife (mountain goats, marmots).

Early Season (Snow) Gear

If attempting in June or early July, or after a high-snow winter, additional gear is essential:

• Microspikes or crampons: For traction on snow and ice
• Ice axe: For self-arrest on steep snow slopes; must know proper use before attempting
• Gaiters: Keep snow out of boots
• Extra warm layers: Cold conditions likely with snow coverage

Do not attempt snowy conditions without proper equipment and skills. The consequences of a fall on steep snow can be severe.

Tips for a Successful Hike

• Start Early: Begin before 7 AM in summer to avoid heat on exposed switchbacks and reduce afternoon thunderstorm risk
• Pace Yourself: The climb is relentless—maintain a sustainable pace with regular breaks
• Count Switchbacks: Some hikers find counting the ~90 switchbacks helps maintain focus and mark progress
• Break the Climb into Sections: Mental waypoints help: trailhead to first viewpoint (1 mi), switchbacks to 5,000 ft (2.1 mi), ridge to Nason junction (3.2 mi), junction to summit (4.3 mi)
• Save Energy for the Top: It’s tempting to rush, but pace yourself for the final ridge walk and summit
• Enjoy the Views: The exposed climb means constant views—take breaks to look around and appreciate the scenery you’re earning
• Protect Your Knees: Use trekking poles for descent, take your time on the downhill switchbacks
• Check Trail Reports: Recent trip reports on WTA or AllTrails provide valuable current condition information
