This is a fabulous park! My first visit was today; we took our one year old basset hound with us. Our first stop was the Nature Center (well-behaved dogs are allowed inside!) where I spoke with the friendly and incredibly helpful staff behind the desk. I wanted to see the Robinson Rockhouse Ruins so the staff member gave us great detailed directions, explaining the trails and a few landmarks and even told us about some of the programs that they have there too. (They do a lot of programming that I think I may take advantage of, especially in the Fall.) We took Umbrella Trail to South Fork then to Robinson Rockhouse Trail to get to the Rockhouse Ruins. Make sure you loop to the right back corner of the house (from the trail) to see the huge Osage Orange tree. I plan to return to the park to take advantage of more trails and maybe the dog park when it isn't quite so busy (what a popular treat for our canine pals!).
