The Sierra Buttes rise as a fractured granite spire above the Gold Lakes Basin in the northern Sierra Nevada, visible from the Sacramento Valley on clear days and identifiable from 100 miles away by their jagged profile. The fire lookout perched on the summit at 8,587 feet is one of the most dramatic destinations in Tahoe National Forest, and the route to reach it is as distinctive as the destination: a steep trail through alpine lake country capped by a series of steel ladders bolted directly to the rock face. It is not a walk in the park, but it is not technical mountaineering either. If you're comfortable with heights and reasonably fit, the payoff is worth every step.
Trail Overview
The standard route from the Packer Lake trailhead is 5.0 miles round trip with 1,571 feet of elevation gain. The trail starts at roughly 6,700 feet and tops out at 8,587 feet. Compared to something like the Five Lakes hike in the Granite Chief Wilderness, this trail gains more feet per mile and finishes on exposed terrain instead of a calm lake basin. Budget 3 to 4 hours round trip for most hiking parties, or up to 5 hours if you spend extended time at the top.
Getting to the Trailhead
From Nevada City, take Highway 49 north through Downieville to Sierra City, about 75 miles total. In Sierra City, turn left onto Gold Lake Highway (Forest Road 621). Drive about 1.5 miles to the Sardine Lake turnoff on the left, then continue past the Sardine Lake resort area to the Packer Lake Road junction. The Packer Lake trailhead parking area is about 2 miles up this road, on the left. Total drive from Nevada City is approximately 90 minutes.
From Truckee, take Highway 267 north to Highway 89 north, then connect to Highway 49 west toward Sierra City. The drive is about 70 miles and takes approximately 1 hour 45 minutes.
The road to Packer Lake is paved to the resort entrance but transitions to packed gravel for the final stretch to the trailhead. Standard passenger vehicles can make it in dry conditions. GPS coordinates for the trailhead: 39.6283, -120.6441.
The Route
Miles 0 to 1.5: The trail begins at the Packer Lake parking area and climbs steadily through lodgepole pine and red fir forest. The grade is moderate for the first mile, giving you time to warm up before the steeper terrain ahead. At about 1.2 miles you'll pass a junction: the left fork leads toward Tamarack Lakes (a longer route to the summit), and the right fork continues on the standard trail. Stay right.
Miles 1.5 to 2.0: The trail steepens significantly here, switchbacking through open rocky terrain with improving views of Sardine Lake and Packer Lake below. Wildflowers are excellent in mid-July along this exposed section: Indian paintbrush, penstemons, and patches of mule's ears color the rocky margins. The grade feels relentless but the trail is well-maintained with no significant route-finding challenges.
Miles 2.0 to 2.5 (the ladders): This is the section that sets this hike apart. As the rocky ridge narrows, the trail transitions to an engineered series of steel stairways and ladders bolted directly to the cliff face. There are multiple sections of ladder, the longest spanning about 20 feet of near-vertical rock. The exposure is real: you are on the outside of a narrow rock rib with drops on both sides. The ladders are equipped with handrails and are maintained regularly. Take your time, don't rush other parties, and keep your hands free. The lookout platform at the top is a 360-degree observation deck at 8,587 feet.
At the summit: On a clear day, the views take in Sardine Lake directly below to the northwest, Packer Lake to the south, the forested ridges of the Gold Lakes Basin spreading in all directions, and the flat haze of the Sacramento Valley to the west. Mount Shasta, 100 miles north, is often visible as a solitary white cone above the northern horizon. To the east, the Sierra Nevada continues south toward Lake Tahoe.
When to Visit
Late June through July: The trail typically clears of snow by mid-June, though snow patches may linger on north-facing slopes near the summit into late June in heavy snow years. Wildflowers are at their best in July. Mosquitoes can be significant around the lakes below through mid-July.
August through September: Prime season. The ladders are dry, the mosquitoes have thinned, and the light is excellent for photography in the morning and evening. Afternoon thunderstorms are possible; plan to summit by noon and start your descent by early afternoon if you see clouds building.
October: The trail is usually open through early October. Temperatures drop, colors change in the lower forest, and crowds thin dramatically. Be aware that early-season snowfall can make the ladders treacherous. Check current conditions before attempting a fall summit.
What to Bring
- Water: Many hikers carry 2 or more liters per person given the lack of reliable water sources after the trailhead. The sustained climbing at altitude increases hydration needs. Individual hydration needs vary based on body weight, pace, and temperature. A filter is useful if you plan to top off from the stream near the start of the trail.
- Layers: The summit at 8,587 feet is windy and exposed. Even on warm days in the valley, bring a wind layer or fleece. Temperature drops 15 to 20 degrees from trailhead to summit.
- Sun protection: The upper section of the trail is completely exposed. Sunscreen, sunglasses, and a hat are essential.
- Gloves: Useful for the metal ladders, which can be cold in the morning and uncomfortably hot by midday in summer.
- Trekking poles: Helpful on the descent. They don't fit on the ladders, so be prepared to stow them in your pack or lean them against the rock while you climb.
Practical Details
Trailhead: Packer Lake trailhead on Packer Lake Road, off Gold Lake Highway north of Sierra City. Unpaved parking lot with a vault toilet. No fee.
Parking: The lot holds about 30 vehicles. On summer weekends it fills by 9 AM. Arrive early or plan a weekday trip. There is limited overflow parking along the road shoulder.
Dogs: Dogs are allowed on the trail, but the ladder sections require honest assessment. A large dog cannot manage the steel ladders unassisted. Most parties with dogs stop at the base of the ladder section and let the humans continue to the top. Small dogs can sometimes be carried. Leash required at all times.
Permits: None required. Free California Campfire Permit required for stoves or fires outside developed campgrounds.
Cell Service: Essentially none. Download maps and trail info before leaving the highway corridor.
Getting There
From Sacramento: Take I-80 east to the Highway 49 exit south of Auburn. Follow Highway 49 north through Grass Valley, Nevada City, and Downieville to Sierra City. At Sierra City, turn left (north) on Gold Lake Highway. After 1.5 miles, turn left toward Sardine Lake. Follow signs to Packer Lake Road and the trailhead. Total distance from Sacramento: approximately 135 miles, about 2.5 hours.
From Reno: Take I-80 west to Truckee, then Highway 267 north to Highway 89 north. At Sierraville, turn west on Highway 49. Continue to Sierra City and follow the directions above. From Reno, allow about 2 hours.
Beyond Sierra Buttes Lookout
For a longer day in the same area, the Tamarack Lakes loop adds about 4 miles and visits a series of alpine lakes below the west face of the Sierra Buttes. This route starts from the same trailhead and is less crowded than the direct summit route.
The Round Lake trail in the Gold Lakes Basin provides an easier complement to the Sierra Buttes hike: if you're spending multiple days in the area, do Sierra Buttes one day and the lake basin the next for a full range of the northern forest experience.
