The Annapurna Circuit is best known as one of the world’s classic long-distance treks, but a growing number of mountain bikers now take on all or part of the same route by pedal, covering in days what trekkers spend weeks completing on foot. The route climbs from subtropical lowland villages through pine forest, past traditional Manang stone houses, and over the 5,416-metre Thorong La pass into the dry, high-desert terrain of the Mustang region beyond.

Riding the circuit is a serious undertaking, combining sustained high-altitude climbing, technical singletrack and jeep-track descents, and the same acclimatisation demands faced by trekkers on the same route. It rewards riders willing to take it seriously with one of the most varied, spectacular multi-day mountain bike routes anywhere in the world.

This guide covers how the Annapurna Circuit route breaks down for mountain bikers, what to expect stage by stage, and how to plan a trip.

Route Overview

The full Annapurna Circuit runs roughly 160 to 230 kilometres depending on the exact start and end points chosen, climbing from around 800 metres near Besisahar to 5,416 metres at Thorong La before descending into the Kali Gandaki valley and the town of Jomsom. Most mountain bikers complete the route in 7 to 10 days, considerably faster than the 15 to 20 days typical for trekkers, though the pass crossing itself still demands the same careful acclimatisation regardless of pace.

Best Time of Year to Ride

October to November and March to April are widely considered the best windows, offering stable weather, clear mountain views, and manageable trail conditions on both sides of the pass. Winter brings snow that can close Thorong La entirely, while monsoon, June through September, turns lower sections of the route to mud and raises landslide risk on several exposed trail segments.

Stage-by-Stage Trail Breakdown

The Thorong La Pass Crossing

At 5,416 metres, Thorong La is the highest point on the circuit and the section that demands the most respect regardless of riding ability, given the genuine risk of altitude sickness at this elevation. Most riders push their bikes for a significant portion of the final approach, since the thin air and steep, loose terrain near the pass make sustained riding impractical for all but the strongest, best-acclimatised cyclists.

Permits and Logistics

Riders need both a TIMS card and an Annapurna Conservation Area Project permit, the same documents required of trekkers on the same route, obtainable in Kathmandu or Pokhara before departure. Most riders base out of Pokhara for pre-trip preparation and post-ride recovery, with transport typically arranged to Besisahar or Chame to begin the route.

Bike Setup and Gear

A full-suspension mountain bike: Strongly recommended given the technical, often rocky and rutted terrain throughout the route

Wide-range gearing: Essential for both the sustained high-altitude climbs and the punishing final push toward Thorong La

A comprehensive spare parts kit: Bike shops beyond Pokhara are extremely limited, particularly past Manang

Cold-weather riding gear: Temperatures near Thorong La can be well below freezing even outside winter

Where to Stay Along the Route

Teahouses line the entire route at regular intervals, the same lodges used by trekkers, offering basic rooms and meals without requiring riders to carry camping equipment. Booking ahead isn’t typically necessary outside peak trekking season, though riders should budget extra time in case a teahouse in a planned stop is unexpectedly full.

Altitude and Acclimatisation

Because mountain bikers cover ground faster than trekkers, there’s a real temptation to skip the acclimatisation days trekkers typically build into their itinerary, a mistake that significantly raises the risk of altitude sickness near Thorong La. Riders should plan at least one rest or acclimatisation day around Manang, regardless of how strong they feel, and should not attempt the pass with any symptoms of altitude sickness present.

Tips for Planning Your Trip

Build in acclimatisation days despite the faster pace: Speed on the bike doesn’t reduce the body’s need to adjust to altitude

Ride with a guide or experienced local support: Particularly valuable for navigation and altitude monitoring near the pass

Service your bike thoroughly before departure: Mechanical support becomes very limited past Manang

Choose the October-November or March-April windows: These offer the most reliable trail and weather conditions

Common Mistakes to Avoid

Rushing the itinerary to save time: The pace advantage over trekking shouldn’t come at the cost of proper acclimatisation

Underestimating the hike-a-bike sections near the pass: A significant portion of the final approach is unrideable for most riders

Skipping a bike service before the trip: Mechanical failures far from Pokhara can end a trip early

Ignoring early altitude sickness symptoms: Continuing toward the pass despite symptoms is a common and serious mistake

Conclusion

The Annapurna Circuit remains one of the most complete multi-day mountain biking routes anywhere in the world, moving riders through subtropical forest, high alpine terrain, and finally the dry, dramatic landscape of Mustang, all connected by a single continuous trail over one of the highest bikeable passes on earth. It demands real fitness, careful acclimatisation, and solid mechanical preparation, but rewards all three generously.

For mountain bikers looking for a genuine Himalayan expedition rather than a single scenic ride, the Annapurna Circuit offers a route that few other trails in the world can match.
