Meadowcroft is a relaxed family site with an Indian village, gift shop, snack food, 19th Century town, hand-on activities, and often historic re-enactors. It could easily take several hours to get through. This tour serves as a good way to make the trip back to civilization seem much shorter.
Raccoon Creek State Park has a swimming lake, trails, picnic and camping areas, and all the usual park facilities. Oh, and it's free.
This trip takes about an hour, so make sure you will have enough daylight to see everything.
Please drive carefully and obey the rules of the road.
