Description of area, sights, wildlife and any key markers on the trail:

Located within the Lakes Basin Recreation Area, Grass Lake is one of many small lakes found within the recreation area that holds significant human history. Of note are the Indigenous history, evidenced by significant modern day remnants from tool making and much more, as well as the history of gold discovery that ultimately resulted in a significantly negative situation for the Indigenous community.

To access this hike, you will have to start within the Plumas-Eureka State Park which has free admission. The trail and area are popular for birding, hiking, and walking, particularly during the summer season. The trail to Grass Lake is a gradual uphill climb for about 1.25 miles. At about the 1-mile point, the trail exits the state park and enters Lakes Basin Recreation Area. Large rock steps in the first half mile have been referred to as “The Stairway to Heaven”.

Along the way you may see the Red Fir forests, and depending on the time of year, you may see seasonal wildflowers or the golden leaves of the Aspens in autumn. For those seeking a longer experience, you may add more mileage to access several of the other lakes or make your way towards the Pacific Crest National Scenic Trail, more commonly referred to as the PCT.

Directions to the trailhead:
At Highway 89 in Graeagle take County Road A14, the Graeagle-Johnsville Road west toward Plumas Eureka State Park and Johnsville. From Highway 70 in Blairsden take Mohawk Road pas the ranger station to County Road A14.

From here proceed on County Road A14 about 3.8 miles to the state park and a sign indicating ‘Jamison Mine’ and turn left onto this dirt road. Continue 1.25 miles to the trailhead. Inside the state park the trail is called Grass Lake Trail.
