At a Glance

  • Historic fire lookout at 6,823-foot summit
  • 360-degree views including into British Columbia and Idaho
  • Western larch forest on the approach
  • Kettle Range ridgeline character
  • One of the more accessible summit lookouts in northeastern Washington

Overview

Grassy Top Lookout sits at 6,823 feet on the Kettle Crest in Colville National Forest, reached by a moderately challenging trail from Forest Road 2030. The historic fire lookout structure at the summit has stood since the 1930s fire lookout era, and the views from its base encompass a genuinely vast panorama: British Columbia to the north, the Columbia River corridor to the west, and the Selkirk Mountains to the east.

The trail climbs through western larch and ponderosa pine, transitioning to open crest terrain near the summit. This is one of the more rewarding summit hikes in the Kettle Range for the combination of old lookout infrastructure and expansive views.

The Route

Trailhead to Tree Line (Mile 0 to 1.8)

From the Forest Road 2030 trailhead, the trail enters a western larch and ponderosa pine forest and begins climbing immediately. The grade is consistent and moderate through the first 1.8 miles. In late September and October, the larch needles are bright gold throughout this section.

Tree Line to Summit (Mile 1.8 to 2.9)

The trail steepens above tree line and reaches the open Kettle Crest. The lookout tower comes into view from about 0.5 miles out. The final approach is the steepest section of the route, gaining the last several hundred feet to the summit.

The lookout structure is at the summit. The views from the summit base are better than from the enclosed lookout building. Return via the same route.

When to Hike

Late June through September is primary season. Snow typically clears from the upper crest by late June.

October is ideal for the western larch color on the approach forest sections.

Start morning visits: afternoon clouds can reduce visibility from the summit.

What to Bring

Many hikers carry 2 liters of water. There is no water on this trail; carry everything from the trailhead. Individual hydration needs vary, particularly on the exposed upper crest in warm conditions.

A windbreaker is useful at the summit, which is exposed to prevailing westerlies.

Trailhead Access

Forest Road 2030 south of Sherman Pass, off Highway 20. Gravel road accessible by standard vehicles in dry conditions. No permit or fee required (as of 2026). No restrooms at the trailhead.

Nearby

The Kettle Crest North Trail at Sherman Pass connects to the same ridgeline and provides a longer option for those wanting to extend into a full Kettle Crest day. The Sherlock Peak Trail is in the same area for a second-day option.
