Easy trail at the outset though there are some technical spots. Very scenic as you follow the river initially. At the start you'll be riding through areas that are frequented by campers and you'll essentially be riding through campsites (though the trail is distinct and separate from these areas for the most part). Eventually the trail will get more technical with some difficult climbs (trail will branch. Left = big climb and loose rocks, right = less climb but more aggressively technical for a short spurt). Both directions will lead to Miller's Rock, a local landmark. Recommend climbing to the top for a dramatic view of the surrounding area and mountains (Long's Peak, etc.). ATV and dirt bike trails intersect at the "top". Lots of oppurtunities to make a semi-epic ride of it. Options include riding down to the town of St. Vrain, heading west towards the Peak to Peak highway, or east to who knows where.... Be careful, easy to get confused what trail one's on if not familiar with the area near Miller's Rock. Boulder Mountain Bike Alliance is planning to reroute portions and clean up areas prone to erosion fall of 2009 which should improve trail quality and signage...
