FORGET THIS PLACE...unless you want to see nature at its finest. Beautiful throughout and extremely well-maintained. It offers drive-by scenery, wonderful and diverse hiking trails, educational opportunities, a nice little café and gift shop, and a very polite and available staff.
Outdoor sculpture is scattered throughout the more civilized areas. They welcome tourists and the local community equally. And on most weekdays, there is no usage fee. You can spend time in the more developed areas, be somewhat secluded on the back of the lake, or very isolated in the more remote areas as you drive deeper into the park and then hike even farther.
No matter what you choose, one thing is clear...nature is the top priority here. It truly is an absolute treasure.
