#55 on the US Top 100 list, this climb travels into the Grand Mesa National Forest (Grand Mesa is the largest flat-topped mountain in the world) and shares its summit with Top 25 US Climb Grand Mesa North (21.4 miles, 6.1%, 5,726' gained - which begins 40 miles to the north of the Cedaredge start for Grand Mesa South).
4.6% average grade - 52% of the climb is at grade 0-5% and 40% is at 5-10%.  The steepest quarter-mile is 9.3% and steepest mile 6.8%.

Roadway:  Two lane Scenic Byway Route 65 is in very good condition with an approximate 2' shoulder most of the climb.  

Traffic:  Mild to moderate traveling at highway speeds (45-55 mph) for the most part.  If you are traffic averse, begin this climb about half-way up the mountain as traffic is milder the further we climb.  We have ridden this climb and the route from the north twice each and have felt safe on each ascent. 

Parking:  In Cedaredge on Main Street at the start of the climb - MapStreet View
Provisions:  There are no provisions on the climb - there are markets and restaurants in Cedaredge at the start of the climb and in Mesa on the backside of the climb, 39 miles from the start - Map.

Weather and Gear
:  We climb to nearly 11,000' and finish about 5,000' above where we begin.  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.
A challenging out and back climb is to tack on Grand Mesa North to this climb - 80 miles and 10,440' of climbing - Map.

Use the “Routes in Area” button on the menu bar above to see other bike climbs in this area.  A fantastic climb not to miss if your are in the area is East Portal, about 50 miles south in the Black Canyon of the Gunnison National Park.

We have stayed in Montrose when we have done this climb, but we would recommend staying in Cedaredge as it seems like a quainter town.

Enter Grand Mesa National Forest at mile 12.

Pass Ward Creek Reservoir at mile 14

Roadway Surface and Traffic Report:  For both the northern and southern approaches to the pass, the roadway is very good and while there is moderate and briskly moving traffic along the first third of the route, the traffic thins as you ascend and was never really a concern for us.

Finish at 10,839’

At the top of the climb, you can take a dirt road to the right to the Land’s End Observatory: 

“Land's End Observatory is a ranger observatory on the rim of Grand Mesa in Colorado. It is accessible from the Grand Mesa Scenic and Historic Byway via Land's End Road, which is about half paved and half gravel. . . . The observatory was built by the United States Forest Service and the Works Progress Administration in 1936-37, with some assistance from two Civilian Conservation Corps (CCC) side camps. A large viewing area outside the building provides a panoramic view of western Colorado and eastern Utah. As of 2014, the observatory building itself is closed and boarded up. . . .”
