Hiking Distance: Approximately 5.6 miles (roundtrip)

Description: On this hike you’ll gain about 1,600′ in elevation.  This trail initially parallels the north side of Stillwater Reservoir, which was constructed back in 1940.  At 0.8 miles you will run into a registration/information board at the junction with trail #1120.  Hang a right at the junction (heading north).  You will reach the Flat Tops Wilderness Area boundary in another .2 miles.  Next, you will pass Little Causeway Lake at mile 1.6.  There is good camping and fishing at the Lake.  From here you climb along and through talus slopes to the Bear River/ E. Fork of the Williams Fork watersheds divide at mile 2.3.  A side trail on your left makes a steep ascent to the Devil’s Causeway.

Please do not attempt to make this hike during a thunderstorm, as we saw many people do last time we were in Flat Tops.  Half of the terrain is above timberline.  The TH is about 10,200′ high and the Causeway is about 11,800′ in elevation.

***CROSSING DEVILS CAUSEWAY IS EXTREMELY DANGEROUS.  DO NOT ATTEMPT TO CROSS IN INCLEMENT WEATHER OR IF YOU HAVE A FEAR OF HEIGHTS!!!  WE TAKE NO RESPONSIBILITY FOR ANY INJURY OR DEATH SUSTAINED BY AN ATTEMPT TO CROSS!!!

Worth Noting: The Devil’s Causeway is one of the most intriguing geologic structures in Colorado.  This basaltic bridge is 50 feet long and a mere 5 feet wide.  However, it appears even thinner when you’re actually on top of it.  It is a 1,000+ foot drop-off on either side of the bridge.  The Devil’s Causeway offers one of the most spectacular views of the Flap Tops Wilderness Area that you could possibly dream up.
