Very nice road, though usually clogged with four wheelers. Avoid rush hour (plenty of Boulder workers live in Nederland) and try for mid-day during the week, not weekends. Who knows, though? It's a crap shoot what kind of traffic you'll encounter. There are some side roads worth noting: Four Mile Canyon up to Gold Hill is a very nice ride. Likewise Magnolia Rd.(turns gravel before you reach Peak to Peak Hwy. south of Nederland.) Sugarloaf Rd. is great: it starts paved and eventually turns gravel, but the scenery is great. Roads like this are why Boulder is heaven for bikers.
DecimusLiving in Denver, I can ride this route 6-8 times a year. Can be crowded with hikers, tubers, rock climbers and gawkers, with their cars parked in the turnouts, so be careful. Nice curves. Well worth the ride.
bkingA wickedly twisty 20 mile section of curves leading down to the lake at Nederland. Try not to get distracted by the climbers on the steep granite faces!
