The Sella Ronda is cycling’s perfect loop. Four spectacular Dolomite passes encircling the Sella Group massif, 55 kilometers of pristine tarmac, 1,800 meters of climbing, and scenery that will have you stopping every kilometer for photos. It’s bucket-list Dolomites cycling—manageable in a day yet utterly spectacular.
What Makes Sella Ronda Legendary
The Four Passes:
- Passo Pordoi (2,239m) - Highest pass in Dolomites
- Passo Sella (2,244m) - Dramatic lunar landscape
- Passo Gardena (2,137m) - Green valleys and vertical walls
- Passo Campolongo (1,875m) - Gentlest of the four
The Loop: Unlike most alpine routes that go point-to-point, Sella Ronda circles back to your start—perfect logistics.
The Scenery: Vertical Dolomite towers, green valleys, ski villages, UNESCO World Heritage geology.
The Accessibility: Strong intermediate riders can complete it. You don’t need to be a pro.
The Culture: Italian rifugios, espresso stops, Ladin villages, and cycling-mad locals.

Counter-Clockwise Route (Starting Arabba)
Same passes in reverse order:
- Campolongo (warm-up)
- Gardena
- Sella
- Pordoi (save hardest for last)
Advantage: Starting with easiest pass (Campolongo) allows thorough warm-up.
Disadvantage: Finishing with hardest pass (Pordoi) when you’re tired.
Reality: Both directions work great. Choose based on preference or wind direction.
Best Starting Point
Arabba: Most popular, central location, good services
Alternatives:
- Canazei: Larger town, more accommodation options
- Corvara: Charming, less crowded
- Selva: Large resort, many facilities
Truth: Start anywhere on the loop—it’s a circle.
Best Time to Ride
Season: May through October, sometimes into November.
Peak Perfection:
- June: Spring scenery, fewer crowds, snow on peaks
- September: Autumn colors, excellent weather, fewer tourists
Avoid:
- July-August weekends: Mobbed with tourists, cars, motorcycles, cyclists
- Monday-Thursday in peak season: Much quieter
Time of Day: Start early (7-8am) to:
- Beat traffic
- Have more time
- Avoid afternoon thunderstorms
- Get better light for photos
Duration: Budget 4-5 hours for riding + 1-2 hours for photos/food stops = full day.
Practical Strategy
Fitness Required: Strong intermediate to advanced. It’s not easy, but manageable for fit cyclists with climbing experience.
Gearing: 34x32 minimum. Some ramps exceed 12%.
Pacing:
- Conservative start: Four passes demand pacing
- Save energy: Especially if doing clockwise (Pordoi first)
- Enjoy: Don’t race—savor the experience
Food Strategy:
- Breakfast: Large breakfast before starting
- Mid-Loop: Stop at rifugio around pass 2 or 3 for proper meal
- Snacks: Carry bars/gels for between passes
- Hydration: Carry two bottles, refill at rifugios
Photo Stops: Budget time—the Dolomites demand photography. Every pass offers incredible views.
Rifugio Culture: Stop at at least one mountain hut for espresso or meal. It’s part of the experience.
The Four Passes: What to Expect
Passo Pordoi (2,239m):
- Hardest climb (665m, some sections 14%)
- Most dramatic views (Marmolada glacier visible)
- Busiest summit (largest facilities)
- Cable car option to Sass Pordoi viewpoint
Passo Sella (2,244m):
- Lunar landscape, less vegetation
- Spectacular rock formations
- Less crowded than Pordoi
- Dramatic descent views
Passo Gardena (2,137m):
- Green valleys contrast with vertical rock
- Perhaps prettiest pass
- Charming rifugios
- Technical descent
Passo Campolongo (1,875m):
- Gentlest (lowest, easiest gradients)
- Forest sections
- Quick ascent/descent
- Good warm-up or cool-down
Difficulty Rating
Advanced to Intermediate: Accessible to strong riders with mountain experience. Not trivial, but achievable.
Comparison:
- Easier than: Three-Pass Swiss Alps days (lower, shorter)
- Harder than: Single-pass rides (cumulative fatigue)
- Perfect introduction: To multi-pass cycling
The Stats: 55km, 1,800m is substantial but not extreme. Pacing is everything.
What to Expect
Physical: You’ll be tired by pass 3-4. The cumulative climbing and mental focus add up. But it’s manageable—thousands of recreational cyclists complete it annually.
Scenery: Prepare to be overwhelmed. Every corner reveals new Dolomite spires, green valleys, and postcard views.
Traffic: Heavy in peak season, especially between 10am-4pm. Cars, motorcycles, buses, and cyclists share narrow roads.
Cultural Immersion: Stop at rifugios, order cappuccino, eat speck and strudel, practice basic Italian/German/Ladin greetings.
Satisfaction: Completing four passes in one day is genuinely satisfying. The bragging rights are earned.
Pro Tips
Weather Check: Thunderstorms develop quickly. Check forecast and have rain gear.
Cash: Some rifugios don’t accept cards. Carry euros.
Bathroom Breaks: Use rifugio facilities. Don’t wait for perfect moments—they’re infrequent.
Bike Mechanicals: Carry spare tube, basic tools. Bike shops exist in base towns but not on passes.
Emergency Bailout: If needed, all passes have descent options to towns with bus service.

Note: In winter, this becomes a famous ski tour—skiers do the circuit using lifts. Summer is cycling season; winter is skiing season.

The Bottom Line
Sella Ronda is cycling’s perfect loop. It’s hard enough to feel accomplished, easy enough to be achievable, scenic enough to be unforgettable, and cultural enough to be enriching.
When you complete the circuit and roll back into your starting town, tired but elated, with 1,800 meters of Dolomite climbing in your legs and hundreds of photos on your camera, you’ll understand why Sella Ronda is considered one of the world’s greatest one-day rides.
The combination of four spectacular passes, UNESCO World Heritage scenery, Italian alpine culture, and the satisfaction of completing a loop makes this absolutely essential.
Book your accommodation, check your gearing, charge your camera, and go ride the Sella Ronda. You won’t regret it.
