It is an easy going community only 16 mi/25.8 km away from Boulder. One of the most popular sports in Boulder is motorcycling. A great spot for motorcycling is Jamestown loop. It is a 9.5 mi/15.3 km loop that follows the river, while you ride high into the mountains.
At many points the river passes through the trail, making you step on footpaths that have been built over the river. The road has loose gravel. The trail makes you work on the ascents, but the technical descent is the one that will blow your mind. The trail starts as a dirt road and turns into a four wheel, drive road that skirts the river.
At 1.5 mi/2.4 km, the water has washed out the entire trail, so you have about 100 ft/30.5 m of water to drive into or by. At 3 mi/4.8 km, there is an intersection with a private property, where you need to cross the stream. Continue on this road and after 3.3 mi/5.3 km go straight up the mountain.
At 4.6 mi/7.4 km, you meet a 3 way intersection. It is suggested to take 509 up a short, rocky section. Continue on a difficult, technical trail part and 5.5 mi/8.8 km further, you meet another 3 way intersection, where you should keep on left. Get off 509 and start an insane downhill, that is extremely difficult.
At the next 6.1 mi/9.8 km, you meet an abandoned mine. You can stop there and relax. At 8.1 more mi/13 km, you meet a well maintained service road; turn right and head to Jamestown. After 8.6 mi/13.8 km, you are back again on the paved road. The trail is regarding physical level, difficult and as for technical level, moderate.
