Boss Lake

Boss Lake is a small reservoir set in a crown of thick forests. It’s a beautiful spot for a hike and picnic, an overnight camping trip or fishing. The hike to the lake follows a steep 4-wheel drive road for 1.2 miles before climbing a winding singletrack for 0.7 miles. It’s not too tough and the views are worth the climb. Enjoy!


For more adventure, hike up to Hunt’s Lake on Trail 1420 from Boss Lake. Look near the south end of Boss Lake for the trailhead. Hunt’s Lake is a bit over a mile one-way from Boss Lake.
