#1 OF 10
MAUNA LOA, HAWAII, USA
We have ridden this magnificent climb twice from Hilo (the southern and steeper route), and twice from Waikoloa (northern and longer route). Mauna Loa is one of the great bike climbs in the United States and the world. How often can you say you have ridden the “#1” of anything in the world? From the Waikoloa side, at just over 62 miles, Mauna Loa is the longest and most epic bike climbs in the world - it will just flat out wear you down, but it is well worth the effort you’ll put into it. And, after riding the longest climb in the world, spend another day climbing Mauna Kea which is not only the world’s hardest climb by bike, but the 6th longest as well. These two volcanoes are just across the road from each other and each are clearly visible from the flanks of the other.

#2 OF 10
This is an extremely challenging road bike climb and the second longest in the world, behind Mauna Loa, Hawaii, USA (100.1 km/62.2 miles). At 87.4 kilometers (54.3 miles), gaining 3,459 meters (11,349’) to a peak of 3,158 meters (10,361’) at 3.6% average grade (a mile near the top averages 10% at around 8,500’ altitude), this is a beast of a climb.
We travelled to Asia in 2019 in part to climb the second longest bike climb in the world.
We LOVE Wuling Pass!!!!!
#3 OF 10
ALTO DE LETRAS, COLOMBIA
ALTO DE LETRAS, COLOMBIA - Often incorrectly referred to as the longest bike climb in the world.
Climbed by PJAMM on 9-12-17
And the top two adjectives to describe this climb are: Beautiful and Lush. The climb is also very, very long (third longest in the world behind Mauna Loa from the Kona side and Wuling Pass East). It is a bit of a trek to get to - we fly first to Bogota (there are many nonstop inexpensive flights from the U.S. and even Europe [Heathrow has nonstop to Bogota], but most travel from Europe requires a layover), then drive 175 km/110 miles to Mariquita where the climb begins.
82 km later . . .
#4 OF 10
LA MUERTA, ECUADOR
La Muerta, Ecuador
4th longest and 3rd hardest bike climb in the world.
Ride 72.5 kilometers to 4,144 meters gaining 4,470 meters at 5.4% average grade.
#5 OF 10
TRAIL RIDGE, COLORADO, USA
Cycling Trail Ridge, CO
43.9 miles (70.6 km) to 12,151’ (3,704m) gaining 7,770’ (2,367 m) at 3% average grade.
At 43.9 miles, Trail Ridge is the second longest bike climb in the United States (behind #1 US/#1 World Mauna Loa), and 6th longest in the world. Trail Ridge is also the highest continuous (i.e., not a dead end) paved road in the United States. Traversing Rocky Mountain National Park, this climb offers spectacular views along the giant switchbacks 20 miles below a summit that tops out at a whopping 12,000'.
#6 OF 10
MAUNA KEA, BIG ISLAND, HAWAII
The 6th longest and uncontested hardest bike climb in the world is Mauna Kea, Big Island, Hawaii. 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).
#7 OF 10
TEIDE FROM SANTA CRUZ DE TENERIFE, CANARY ISLANDS, SPAIN
Teide from Santa Cruz de Tenerife is 63 kilometers/39 miles - longest bike climb in Europe.
#8 OF 10
DEATH ROAD, BOLIVIA
Cycling the Death Road
#5 hardest bike climb in the world and the 8th longest.
The Death Road is our all-time favorite climb by road bike. We included the Death Ride in our 2017 South American Cycling Adventure (also included were 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!
#9 OF 10
PASO PELHUENCHES, CHILE
Cycling Paso Pelhuenches
60 km (37.7 m) to 2474m (8,117’) at 2.6%
#10 OF 10
HALEAKALA, MAUI, USA
Haleakala Crater as seen from the road near the top of the climb.
Ride 35.6 miles/57 km, gaining 9,988’/3,069m to 10,068’/3,044m at 5.3%
We have ridden Haleakala four times from Paia, and once up Highway 37 from near the airport in Kahului. We recommend the Paia route as it is more scenic with less traffic. This climb is so difficult because it just wears you out: 36 miles of straight climbing and generally between 5-7% average grade (the steepest mile averages only 7.8%). There are some of the greatest hairpins in the US on this climb, most of which are unobstructed (we are on a volcano after all), and the eight starting at mile 25 rival the Horseshoe Meadows Hairpins in length -- the five longest average 1.25 miles each! The wind is almost always blowing along the big hairpins, causing you to ride into the wind suffering for one leg, then turn and are loving life for the next mile and a quarter with the wind at your back.
