When road cyclists talk about riding heaven, the high Alpine passes of France or the jagged peaks of the Italian Dolomites immediately dominate the conversation. And within the Dolomites, no loop is more iconic, revered, or breathtaking than the Sella Ronda.
The Sella Ronda circles the majestic, fortress-like Sella Massif (Gruppo del Sella), connecting four world-famous valleys and ski resorts: Alta Badia, Val Gardena, Arabba, and Val di Fassa. Thanks to a seamlessly paved network of mountain roads connecting four legendary passes, cyclists can orbit this giant limestone monolith in a single, unforgettable day.
🚴 Sella Ronda on a Road Bike: Key Stats and Profile
Cycling the paved Sella Ronda means conquering 4 iconic mountain passes, two of which soar well above the 2,000-meter mark.
- Distance: approx. 52–55 km (32–34 miles)
- Total Elevation Gain: approx. 1,750 m (5,740 ft)
- Route: Arabba ➔ Passo Pordoi ➔ Passo Sella ➔ Passo Gardena ➔ Passo Campolongo ➔ Arabba (or vice versa)
- The 4 Mountain Passes:
- Passo Pordoi – 2,239 m (7,345 ft)
- Passo Sella – 2,240 m (7,349 ft)
- Passo Gardena – 2,121 m (6,958 ft)
- Passo Campolongo – 1,875 m (6,151 ft)
🔁 Clockwise or Counter-Clockwise?
One of the greatest advantages of the Sella Ronda is its compactness. Packing over 1,700 meters of climbing into just 50-plus kilometers means constant action, smooth switchbacks, and jaw-dropping vertical rock faces towering above you at every turn.
- Clockwise (Orange Route): The more traditional and popular direction. The climbs flow naturally, offering a rhythmic effort with rewarding descents.
- Counter-Clockwise (Green Route): Offers slightly different gradients and pitch lengths, but delivers equally spectacular panoramic views.
💡 Pro Tip for Peace & Quiet: To avoid heavy motorcycle traffic and tourist campervans, avoid visiting in peak July and August. The best windows for riding are June or September, when the weather is crisp, alpine colors pop, and traffic is minimal.
🚵 Sella Ronda on MTB & Gravel: Singletrack and Cable Cars
If you prefer dirt, dust, and fat tires over smooth tarmac, the Sella Massif offers a completely different adventure. Surrounding the massif is a vast, world-class network of singletrack trails, gravel paths, and high-altitude fire roads.
- Lift-Assisted (Hero Style): You can use the extensive summer cable-car network to haul your mountain bike to the top of the passes, saving your legs for technical singletrack descents down into the valleys. (Note: Requires a regional summer bike-pass).
- Pure Muscle Power: For endurance-hungry mountain bikers, the official off-road Sella Ronda MTB track covers around 58 km with over 3,300 meters of climbing if done entirely without lifts.
We rode our XC bikes up several mountain trails to the chairlifts and back down. In the afternoon, we changed into our hiking shoes and walked the mountain trail from Paso Pordoi to Marmolada.
The singletrack trails on the Sella Ronda are very well maintained. Their downside is that they run from the chairlift to the lower station. If you’re a tourist and you came with a mountain bike, you’ll have to pay.
🟡 Sella Ronda Bike Day: Car-Free Paradise
Every June, the region hosts the famous Sella Ronda Bike Day. On this day, all four mountain passes are completely closed to motorized traffic. Handing over 50 kilometers of pristine alpine asphalt exclusively to tens of thousands of cyclists.
If you enjoy a festive atmosphere, vibrant crowds, and the rare luxury of descending Alpine passes without checking for oncoming cars, it is an absolute bucket-list experience. However, if you seek quiet solitude and nature’s silence, choose any regular day outside of the event.
🏡 Where to Stay: Why Arabba is the Perfect Base
Arabba serves as arguably the best hub for riding the Sella Ronda. Nestled right at the base of both Passo Pordoi and Passo Campolongo, it offers excellent cycling-friendly accommodations and reasonable rates outside the winter ski season.
Furthermore, staying in Arabba puts you within striking distance of other legendary Dolomite rides. Such as the brutal Passo Fedaia / Marmolada Loop or the scenic trek over Passo Valparola towards Cortina d’Ampezzo.
📝 Rider’s Summary:
- Difficulty: 3.5/5 (Thanks to the short 50 km distance, it is manageable for any well-trained amateur cyclist).
- Gear Essentials: Pack a windproof jacket for the chilly high-altitude descents, keep a camera handy, and make time for an authentic Italian espresso at the top of every pass.
