Hwy 7 begins in Lyons, Co and heads southwest up the St Vrain Canyon until it meets with CO 72 the Peak to Peak Hwy.
As you leave Lyons, Hwy 7 passes through some red rock hillsides before winding up the St Vrain canyon. There are spots alongside the road where you can pull off and enjoy the rushing waters of the creek. Further up the canyon it widens out, where in spots you can see the hills of the Front Range. Finally at the top, there is a wide T intersection where motorcyclists typically pull over for a break.
Hwy 7 got repaved in 2010, so it's smooth as a baby's butt. Most turns have good sight lines, and the road has a great flow and rhythm to it. On summer weekends it can get crowded with traffic, so pass with care or ride it early or late in the day.
Gas and food are available in Lyons. Oskar Blues has been serving up great bar food for years. There is also the Stone Cup cafe if you want a low key vibe. Gas is at the Diamond Shamrock. One more thing, observe the posted limit in Lyons city limits; the local LEO are onto motorcyclists.
