INTRO

OH MY! Yes, this is a MUST-DO climb, no doubt about it. This route has been described as one of the most beautiful climbs you've never heard of - though judging from the crowds we found on an early September Monday, the secret may be getting out. From Locana, the climb runs 39.9 km (24.8 mi) and gains 2,040 m (6,693 ft) at a 4.9% average grade (5.6% with the descents factored out), topping out at 2,546 m (8,351 ft) at the Colle del Nivolet - one of the ten highest paved passes in the Alps. The last third of the ride is what earns the reputation. After a roughly 3 km (1.9 mi) tunnel through the mountain (or the refurbished old road around it, if you'd rather skip the tunnel), the road breaks out along the glacial lakes of Serrù and Agnel inside Gran Paradiso National Park, Italy's oldest national park, before a final set of hairpins onto the high alpine plateau at the Colle. We were blessed with perfect weather, clear skies, and blooming wildflowers for our one shot at this jewel - we rank this bike climb as THE World's Most Scenic Bike Climb - see our Top 10 World's Most Scenic page. The upper stretch is also one of the lightest-traffic high-alpine roads you'll find in the Alps: the final kilometers past Lago di Serrù close to private cars on summer Sundays and holidays, and access above Ceresole Reale is capped in peak season - both of which mean a cyclist often has the mountain nearly to themselves.

PLAN YOUR ROUTE

We've partnered with Sherpa-Map.com to bring you the best route planning tool. With a PRO Membership you can use this climb as a reference when creating your route.
The average grade is 4.9% over 39.9 km (24.8 mi) - 5.6% with descents removed from the equation.  44% of the climb sits in the 0-5% band, 41% in the 5-10% band, and 7% in the 10-15% band.  The steepest 500 m (0.3 mi) averages 12.6%, and the steepest kilometer (0.6 mi) averages 11.0%.
Roadway:  A narrow, two-lane road with no center stripe that continues just past the summit before ending.  Pavement is in good condition throughout.  At km 14.8 the road enters a roughly 3 km (1.9 mi) tunnel; the old road around the tunnel has been fully refurbished in recent years and makes a fun, quiet alternate if you'd rather skip riding through it (see Photos & Videos for details). Traffic:  Mild to moderate for the first third of the climb, then minimal for the last two-thirds - and the upper stretch is unusually quiet for a high-alpine Alps road, since the final kilometers past Lago di Serrù close to private motor vehicles on summer Sundays and holidays, and access above Ceresole Reale is capped in peak season.  A free shuttle also runs Locana-Noasca-Ceresole-Nivolet in summer, which keeps casual driver traffic further down. Parking:  There is public parking on the left soon after you enter Locana from the east - MapStreet View.
Provisions:  There are several cafés or bars to eat and get beverages on the way, the last at Lago di Ceresole around km 22.5 (13.9 mi) - nothing beyond that until the summit, so top off water there.  The Colle sits at 2,546 m (8,351 ft), so pack a wind layer even on a warm morning in Locana - temperatures at the pass run noticeably cooler than in the valley.

We stayed in Turin and drove to the climb.  From Turin you can also access several other great climbs such as Colle delle Finestre. The climb passes straight through Gran Paradiso National Park, Italy's oldest national park (established 1922) and home to a protected ibex population, and Ceresole Reale - the small alpine village on the shore of its own reservoir about two-thirds of the way up - makes a good rest stop before the final push to the lakes and hairpins above. If you'd rather ride it car-free, Nivolet Bike Day closes the road entirely to motor traffic for a few hours each summer - check the Comune di Ceresole Reale's site for the current year's date.

CLIMB SUMMARY

Cycling Colle de Nivolet, Italy - panoramic view shows road snaking up green mountain pass, blue alpine lake at top of mountain

Cycling Colle de Nivolet, Italy.

A World Top 10 Most Scenic Bike Climb.


OH MY!  Yes, this is a MUST DO climb, no doubt about it.  This route has been described as one of the most beautiful climbs you have never heard of.  However, judging from the many cyclists we encountered on the route on an early September Monday, the secret is out!  The last third of this climb is among the most spectacular and breathtaking you will ever find.  We were blessed with perfect weather, clear skies and blooming wildflowers for our one shot at this jewel.

We begin in the small, quaint village of Locana at the Parco Nazionale Grann Paradiso Visitor Center.  Here, you can obtain information about the park, including roadway and hiking routes.  There is another Visitor Center in Ceresole Reale (western end of Lago di Ceresole) at about mile 13/kilometer 21, although it was closed at noon when we arrived.

The first set of hairpins encountered on the climb are in Planchette at kilometer 13.4.

This is the longest top climb in Italy.  The first 17 miles (27 kilometers) have their steep sections, but for the most part are not too difficult, averaging 5% over that long stretch.  Once we are in sight of the second set of major switchbacks as we approach the dam at Lago Serro, the grade begins to increase for good, with the final 8 miles(12.8 kilometers) a 50% greater average grade at 7.5% with a fair amount of that approaching and entering double digit territory.

At kilometer 14.8  we enter a very long  3,200m (2 mile) tunnel.  There are no warnings or restrictions for bicycles as you see on some roads and tunnels.  However, the tunnel is dangerous and should be avoided.

Old road -- alternate route around tunnel.

The old road is to the right, about 100 meters before the tunnel – take that!  The tunnel is terrifying and dangerous and is to be avoided at all costs.  Additionally, the old road is unique and interesting - adding to the allure of this climb.

Boulder blocked our way in 2017, but was removed for the 2019 Giro d’Italia.

The old road is an experience unto itself.  We travel along a river to our right on a worn and broken stretch of pavement, previously past a huge boulder that blocks all but a skinny cyclist.  The 2019 Giro d’Italia featured a mountain finish at the Turino dam on the Colle del Nivolet route on Stage 13, meaning that the giant boulder that blocked our way in 2017 was removed.

The extraordinary nature of the climb begins around kilometer 21 as we reach the beautiful lake and recreational area of Lago Ceresole, two kilometers after the end of the tunnel alternate route. We spent at least an extra hour on this climb stopping to take photographs – we kept telling ourselves, “OK, this is the last set of photos, we have to get going,” but inevitably we didn’t travel much further until stopping again to take more photos of spectacular once-in-a-lifetime views.

This is one worth traveling to – it is a Must-Do Bucket List Climb that words simply cannot describe – photos are a good indicator, but not an adequate substitute for climbing what we consider to be The Most Beautiful Climb in the World.
