The ride begins on Hwy 36 on the outskirts of Boulder, Colorado, and heads north to the town of Lyons. Lyons has a visitors center in a small park (with a water fountain), a brewery, and a nice coffee shop on the back street (The Stone Cup, 442 High St). The real climb begins in Lyons and continues up S. St Vrain Canyon (Hwy 7), through a beautiful winding rock canyon, with a river. There is car traffic on this road, but the shoulder is wide enough.
Take a left turn off of Hwy 7 to the town of Raymond and be sure to buy water, there isn't much more until you reach the town of Ward. After the discovery of Gold nearby, Ward was one of richest towns in the State of Colorado in 1860. Today Ward is a small shabby town, well-known for it's General Store (and picnic table outside) and the tickets given to cyclists who don't stop at the town's 2 stops signs.
SuperJames is another steep ride above Jamestown; more info at map and photos on Bicycling.
