Arch over the start of the MIGHTY and merciless Zoncolan!

Summit -- PJAMM reaching the pass from Ovaro.
OUCH!!! After Scanuppia, the Monte Zoncolan bicycle climb (from Ovaro and Priola) may be the most difficult (at least the most painful) of climbs in all of Italy. No wonder it has only been included in the Giro six times! But, the Giro returns to Monte Zoncolan with a mountain top finish on May 22, 2021 (stage 14) from the Sutrio side of the summit (PJAMM Cycling Monte Zoncolan from Sutrio)

Ride 9.9 kilometers gaining 1,157 meters at 11.8% average grade.
2021 GIRO D’ITALIA
After a 2 year hiatus, the Giro d’Italia returns to Monte Zoncolan May 22, 2021 for a Stage 14 mountaintop finish. However, while the traditional route up Zoncolan is from Ovaro, the Giro features the mountain from the Sutrio side in 2021.
Below is a table from Wikipedia showing the previous 6 Giro d’Italia appearances for Monte Zoncolan in the Giro:

Chris Froome (GBR)
There are three routes up Zoncolan, two of which (Ovaro and Priola) are beasts -- murderous, punishing ascents. The third, Sutrio, is quite manageable and a “pleasant” climb up the mountain, until its fatal intersection with “The Old Road” from Priola, and thence we spend 2.1 miles / 3.3 km at a punishing 12.7% average grade.
Pass through Liariis at kilometer 1.6,
400 meters from here the climb begins in earnest.
Bring your climbing legs for this extraordinary road bike climb -- Monte Zoncolan from Ovaro is the thirteenth most difficult climb in Italy (which is saying something, as Italy is home to an unbelievable 26 of the World Top 100 bike climbs, more than any other country!). Monte Zoncolan is also the and #52 most difficult climb in the world. This is also the tornanti (hairpin) route up to the pass, with roughly 24 hairpins in the brief 9.9 km / 6.2 miles we are on the mountain.
24 tornanti (hairpins).
Traffic and Roadway Surface Report: The roadway is in excellent condition along this climb, and there is generally not much traffic on it. Keep in mind that there are three fairly short but dark tunnels near the top, so be sure to bring lights for your climb.
Tunnel - Bring flashing taillights and a high lumen headlight.
There are three tunnels at the top of Zoncolan from Ovaro, and,
while they are fairly short you should bring lights to be safe.
Below are all of the kilometer signs on the Monte Zoncolan climb. If a year for a Grand Tour is listed, that means the rider won the event that year, unless specified otherwise (e.g., if he was KOM).

Wikipedia provides an excellent summary of the three Zoncolan ascents:
“The mountain can be climbed on three roads: One from Ovaro, another from Sutrio, and a third from Priola.
West from Ovaro: This is a very demanding climb, and one of the most difficult in Europe, usually compared to the Alto de El Angliru. It was featured for the first time in the 2007 Giro d'Italia. The climb starts in Ovaro in the Gorto valley, and is 10.1 kilometres (6.3 mi) long at an average of 11.9% with an elevation gain of 1,210 metres (3,970 ft) and a maximum gradient of 22%. The real climb however starts at Liariis, 8.5 kilometres (5.3 mi) from the summit. Shortly after the village, the road disappears into forest and gains 900 metres (3,000 ft) in the next 6 kilometres (3.7 mi), averaging thus 15%. After this section, the road passes through three short tunnels, before a series of steep switchbacks immediately beneath the summit. The former rough asphalt between Liariis and the tunnels was replaced in 2007; that between the last tunnel and the summit had already been resurfaced by autumn 2005. The tunnels are now lit.”
Plenty of evidence of the Giro on the climb.
