Emerald Lake is the smaller counterpart to neighboring Lake Helen in a scenic area surrounded by the mountains of Lassen Volcanic National Park. Surrounded on all sides by forested hills, the lake and its reflected rock formations create a spectacular sight. Sit on the pebbly shore and set up a picnic with your family in the serene spot.
Work on your tan on a sunny day or take shelter in the shade of a tree. The lake covers a glacial bowl at the foot of Ski Heil Peak. Read the plaque at the side of the lake to get an idea of the natural history, ecology and geology behind its formation.
On warmer days, go for a swim in the clear, calm and very cool water. Notice the bright colors beneath the surface of the water. The greenish hues are an indication of how shallow the lake is. Sit on one of the boulders perched over the water and enjoy the views. You can also climb to the top of the surrounding hills for an excellent vantage point from which to view the lake.
Enjoy a hike with your family along the Bumpass Hell Trail. The loop runs for about 3 miles (5 kilometers) and typically takes 2 hours to complete. Visit the lake in winter to see it covered in a thick layer of ice and snow.
Walk east for 10 minutes to reach the larger Lake Helen, which has a much darker shade of blue. Due to the high altitude, both lakes are cold and even frozen for a large part of the year.
Emerald Lake is a little north of Mill Creek in Lassen Volcanic National Park. Drive between the two in about 30 minutes, passing landmarks such as Brokeoff Mountain, Sulphur Works and Kohm Yah-mah-nee Visitor Center. Park your car at the Bumpass Hell Trailhead. Winter access to the lake is limited to snowshoeing or skiing from the visitor center.
