INTRO

Pozza San Glisente translates to "sandy slippery", but it should be called ripido e impossibile (steep and impossible)!  This is the hardest bike climb in Italy and the fifth hardest bike climb in the entire world.  Only 6 cyclists have climbed this monster according to the Strava segment for it. This is an epic climb that should be on every serious bike climbing cyclist's must-do list.

Roadway:  This is an extremely narrow roadway.  The majority of the route is paved with no center line or shoulder and in fair condition with debris.  The last couple of kilometers is paved narrow strips where the tires of a car would run with dirt or weeds in between and the final segment is large rock and dirt in a rough cobblestone arrangement.  This climb can be done on a road bike but is best suited for a gravel bike. 

Traffic:  Minimal, but be careful on tight turns for descending vehicles because the roadway is extremely narrow. 

Parking:  There is a spot for 2-3 vehicles at a trial head 180 meters up the road from the start - MapStreet View
Provisions:  There are no locations for food or water on this route.  There are many places to get food and beverages in Esine just to the northeast of where our climb begins.

Gear:  This is an almost impossible bike climb.  If you try this on a road bike, be sure to use a bike with gearing to fit your ability, or a mountain bike with small chainring and large cassette.
We suggest you include this climb (if you are up to the challenge 👍) in a trip to the magnificent cycle climbing area of Bormio - see PJAMM Cycling Bormio, Italy climb page; the start of Pozza San Glisente is only about 100 kilometers from Bormio - Route Map

This is the Top Ranked Italian Bike Climb and the fourth hardest in the world. Many online argue that this is the hardest bike climb in the world (see the writeups on Pozza San Glisente on ClimbByBike.com, CyclingToday.com, and Road.cc to hear why they think so).  We agree that this climb is definitely among the toughest around.

How do you get to be the top dog in one of the greatest cycling countries in the world?  STEEEEEPPPP and more STEEEEEPPPP!!  Only the extraordinary Scanuppia with its average 17.8% gradient rivals Pozza San Glisente’s extreme gradient, and Pozza actually edges out Scanuppia for steepest 500 meters at 26.7% versus 24.1%.

First segment of the climb is on a narrow paved roadway.  The next portion is on a one-lane road with two narrow paved sections separated by a grass (and at times rock) center divider, which can be seen in the photo above.

The final segment is very rough cobble or cobble-dirt.  Makes for an extremely bumpy descent.
