Where's a great, not-so-challenging place to hike if I live in Rolla?

Last week, Carrie Bellue asked us this on our Facebook page:
I'm in south central missouri near rolla, and new to the state. I love nature but don't know where to start exploring. I'm in my 50s so I'm NOT looking for a backpack trip or anything too strenuous. Give me a day trip assignment...where's a good place to begin????

We asked some of the folks who adminster parks in that area for their very best recommendation. Here's what they came up with: Montauk State Park, which is about 50 miles from Rolla has a nice 1/2 mile trail called the Montauk Lake Hike. The trail circles a small lake with catch and release for trout. Bluff Spring feeds the lake. One can see wild life out and about along the trail. Montauk also provides peaceful fishing along the headwaters of the Current River which is stocked daily with trout. The park also offers lots of goodies in the retail store and a full service restaurant.
