Clear Creek Trail

if you only have time to do one hike in the Cimarron Canyon State Park, this is the one I highly recommend.  It is very scenic.  The trailfollows Clear Creek to numerous waterfalls.  These falls are a great place to relax.  The trail is well-maintained, so it's impossible to get lost.  I was pleasantly surprised, however, to find the trail keeps going beyond the falls and takes you up a large hill before finally running out/ending.
