Is the walk there difficult?

Going down is easy, coming back up is bit difficult. It is all downhill from the top of mountain /parking lot/ vista point to the lake shore. The trail is basically a wide paved road, which was closed to vehicular traffic when we visited. There are several other dirt trails along the perimeter of lake/hills/creek etc, once you reach the bottom.

If you are out of shape like me, then yes. Lol. The walk down was fine but after a long day the walk up was brutal for me.its about 1.5 up hill

It is a moderate uphill 1 mile walk on the way up. Going down is piece of cake. Its not too steep... Take your time, enjoy the views and it would be worth the effort.

It's a very steep, Rocky, long path.
