A fleeting, mercurial taste of mountains...that's the quicksilver feeling you get on the Siltstone Trail. I am sure any kid with imagination will see these knobs of nearly 400-ft (of vertical relief) as cold and forbidding summits.

I am sure any kid with imagination will see these knobs of nearly 400-ft (of vertical relief) as cold and forbidding summits. Unlike eastern Kentucky's summits, the pine beetle hasn't molested the piney tops of this park. If only sandstone outcroppings existed. If you start at the Welcome Center and hike the Siltstone trail as an out-and-back, then you've climbed 3,630 ft of elevation over 12.6 miles. The forest has over 30 miles of trail with an approx. 10,000 ft of cumulative elevation change. This urban forest is so amazingly close to downtown Louisville that you could grab a Heine Brothers coffee, drink it still-warm at your first step on the Siltstone, and have a post-trail Wick's pizza and not spend more than 6 hours.
