This is the 2nd time we've visited Three Creeks and it was great, as usual. This time we took the 3 mile Interpretive Trail which was very well marked and highlighted the many different terrains in Missouri. Several really great spots for the kids to take a break and cool off in the creek. On our previous visit, we took a different trail, which was more strenuous and not as well marked but my family really enjoyed that one as well. If you are a semi-experienced hiker, you would have no trouble on the trail. I would recommend a minimum of 2 hours to do the hike.
