The 10 Hardest Cycling Climbs in the World

World’s #1 Bike Climb -- Mauna Kea

Sign at the Visitor Center: Still 8.3 miles to go at 10.4% average grade to 13,712’.

PJAMM Cycling has personally documented all of the World’s Top 10 Bike climbs, an adventure that has taken us all across the world and to four different continents.   In reverse order, the following is a summary of the Top Hardest World Bike Climbs as defined by the PJAMM Difficulty Index.

#10 OF 10

LLANO DE LAS ANIMAS, SPAIN

Ride 15.6 kilometers (9.7 miles) gaining 2,000 meters (6,560’) at 12.6% average grade.

Dani Avila, Spain, tard0d lifestyle.

The gradient profile for this climb says it all - there are several segments of extraordinary steepness.  Add the length and altitude of this climb and you have the legitimate runner up to Mauna Kea for World’s Top Bike Climb.

Remaining:  2.9 km @18%.

#9 OF 10

ALTO DE LETRAS, COLOMBIA

The hardest climb in the cycling crazed country of Colombia clocks in at number 9. This extremely long (almost 50 mile) climb snakes through lush rainforests to over 12,000ft above sea level.

#8 OF 10

EL TORNEADO, ECUADOR 

Cycling El Torneado - World #9

Ride 32 kilometers gaining 2,716 meters at 8.4% average grade.

Some of the world’s hardest climbs are in the Andes Mountains of South America, and this is surely one of them.  As with the other top 10 World Bike Climbs in Ecuador (3 in all), this climb is through extremely lush surroundings and finishing in foul weather - nice at the bottom, bad at the top!

#7 OF 10

Al Jaadah Pass, SAUDI ARABIA

Ride 7.7 miles gaining 5,820’ at 14.5% average grade.

The first of 2 top 5 world bike climbs in the Asir Mountains.  This climb is undiscovered by the cycling world (no Stava segments when we climbed it in November, 2021 (here is our segment - Al Jadaah (PJAMM World #2).

The climb is one of the most epic we have ever done - it is extraordinarily challenging, very scenic and untouched by cycling wheels.

We had the great honor of riding with Saudi Arabia’s first women's national cycling champion (2020; and reigning champ 2021), Ahlam Zaid (center of above photo).

#6 OF 10

PUNTA CALLAN, PERU

If we were to know of all the cycling roads starting at the Pacific and reaching up into the Andes, South America would completely dominate the world’s hardest and longest climbs list (more than it already does). Punta Callan is no exception - this is a remote climb on a monster scale, ending at nearly 14,000ft above sea level, (higher than all but 2 climbs in the United States)

#5 OF 10

DEATH ROAD, BOLIVIA

Cycling the Death Road, Bolivia

Ride 39 miles gaining 11,640’ to elevation 15,200’ at 5.5% average grade.

The Death Road is our all-time favorite climb by road bike.  We included the Death Ride in our 2017 South American Cycling Adventure (which also included Alto de Letras, Colombia, Atacama, Chile and Uturuncu, Bolivia). We spent three days on the Death Road and enjoyed every minute of it -- this is the cycling adventure of all time!

#4 OF 10

APAGUA PASS, ECUADOR

Cycling Apagua

Ride 41 miles gaining 11,854’ at 5.4% average grade.

A World Top 20 Road Bike Climb.

This is the hardest climb in Ecuador and that is saying something - Ecuador has an unparalleled 3 climbs in the World Top 10 - more than any other country.  After finishing the climb, be sure to continue on to the magnificent Laguna Quilotoa (a crater lake) 24 kilometers north of Apagua.

#3 OF 10

BABUSAR PASS, PAKISTAN

Ride 26 miles gaining 10,354’ to elevation 13,688’ at 7.5% average grade.

Pakistan’s hardest bike climb and the world’s #3.  The Babusar pass is one of the highest paved road passes in Pakistan. The high-reaching pass is at an altitude of 4173m. The Babusar Valley comes on the road passing from Kaghan Valley.  This road soars through Naran, Batakundi, Besal, to the Babusar top -- the highest point of the valley.  The road  goes down to Chilas (altitude 1265m), situated on the Indus Riverbank surrounded by barren high scale mountains.  The temperature is pretty hot down there as well.

#2 OF 10

LA MUERTE, ECUADOR 

Ride 45 miles gaining 14,670’ to elevation 13,595’ at 5.4% average grade.

With a name that instills fear, this beast is 72.5 kilometers up to 4,144 meters at 5.4% average grade.  Unfortunately, on the day we climbed this one, the weather conditions were horrendous and could get almost no scenic photographs from our ride.

#1 OF 10

MAUNA KEA, BIG ISLAND, HAWAII

TOP RANKED CLIMB IN THE UNITED STATES AND WORLD

40% less oxygen at 13,000’ than sea level . . .

. . . makes 12% feel like 20+.

The hardest bike climb in the World is Mauna Kea, Big Island, Hawaii, and is also by far the most difficult bike climb in the world.  Mauna Kea has it all: length (42.5 miles), altitude (sea level to nearly 14,000’), and gradient (the last 10 miles are from 8,120’ to 13,779’ at 10.7% average grade).

Enough said  😟😟

The gradient ramps up at mile 30 and averages 10.4% for the final 12 miles from 7,200’ to 13,811’ at the finish.

We have climbed Mauna Kea 4 times - 2011, 2013, 2014, 2018.
