Half way between Sacramento and Lake Tahoe, here is a cool place to stop by! This is located in Sky park recreation area, stop by south of Jekinson lake and you can start that loop trail of 8 miles that goes all around the lake!

I really enjoy that hike, it is calm and through the forest, only a part of it is passing by near campsites. And the lake is making that beautiful reflection of the trees on its surface!
Note: for those who are mountain biking, this is a good spot to ride!
