This trail is known mostly as 'Cool', but it's official name is 'The Olmstead Loop'. Once known as 'The Knickerbocker Trail', it was renamed in memory of a local mountain bike advocate, Dan Olmstead, who succeeded in gaining access to what was previously a horse trail.

This trail is well suited for all levels. Beginners will have to be careful, in a couple of spots, but should be able to ride all of the trail except for several slippery rock up-hills. This trail is very popular with equestrians, so always be on the lookout and remember that they have the 'right-of-way'.

The trail has several stream crossings, a couple of challenging climbs and of course... 'Cool' down-hills. One other thing that you may really appreciate, at the end of the ride... There's a hose in the parking lot, which allows you to wash the mud off of your bike and equipment.

All 'n all, a 'Cool' ride!


The trail is ridden by most, as a counter clockwise loop. The trail-head is to the right of the parking lot, across the road that you came in on.

At the left end of the parking lot is the other end of the loop... This goes to the infamous stream crossing that attracts spectators, during the Cool MTB Race. There are several ways to take the loop, with plenty of signage... Enjoy your ride!

Note: You will encounter several cattle gates, along the trail... Please be sure to close them, after you pass through.
