"Another moderate grade and high altitude climb, the east side of Juniper Pass is very scenic in places. You may find more bikes on this road than autos on many days which is a nice change.  The grade is steady and through thick woods almost all the way up and never steep," (This quote provided with approval from John Summerson from his book, The Complete Guide to Climbing (by Bike) in Colorado pg. 102.). 
4.3% average grade (4.7% climb only). 48% of the climb is at 0-5% grade and 45% is at 5-10%.  The steepest quarter-mile is 7.9% and steepest mile 6.3%.

Roadway:  Two lane highway in good condition with a narrow shoulder much of the climb. 

Traffic:  Mild. 

Parking:  At the park across the highway from the start of the climb - MapStreet View
Provisions:  None on the climb but plenty in Bergen Park where the climb begins. 

Weather and Gear:  We travel to 11,000 (33% less oxygen there than at sea level - we lose 3% every 1,000') - so be sure to consult the PJAMM "Full Forecast" feature for the time you expect to arrive at the finish to assess what clothing to bring on your ride.

Doing Juniper Pass East with Juniper Pass West is a nice out and back - 62 miles gaining 7,210' (Map).  Or, add the last 14 miles of Mount Evans - the turn off to Mt. Evans Road is just 2.3 miles down the road from Juniper Pass and the first 13 miles of Mount Evans and Juniper Pass West overlap.  Mount Evans is the highest paved road in North America.
