The lake has a large parking lot near the park entrance and a 1 mile trail that goes all around it. The far end of the trail is a bit trickier with a path that goes thru the rocks. Gorgeous trail and very clean. More

This is our favorite lake to go fishing in, and it is so beautiful. Go in the morning, when there is no wind, the water is a mirror reflecting the rocks out in the lake, picturesque!!!!!!!!!!!!!!! More

This is the place to go for swimming. It's big, and open, and tons of people go there. It's a tourist spot no doubt. . More
