Cycling in Southern Passes
Southern Andorra: Coll de la Gallina — the hardest climb in Andorra at 8.7% average — plus Creu de Batlle and gravel into the Spanish Pyrenean frontier.
Last updated: 15 March 2026
The southern zone of Andorra, anchored by Sant Julià de Lòria — the country's southernmost parish at 909m — is the principality's most demanding climbing territory in terms of raw gradient. Coll de la Gallina, rising from below 900m to 1,910m in 12km, averages 8.7% and reaches 13.8% on the defining central section, making it the hardest sustained ascent in Andorra and one of the most demanding HC climbs in the eastern Pyrenees. The 2015 Vuelta a España used it as a summit finish stage, which brought it to the attention of the professional peloton, but the climb remains largely unknown outside Andorra — an extraordinary oversight given that its gradient character places it above many celebrated Spanish climbs in terms of difficulty.
The approach to Coll de la Gallina from Sant Julià de Lòria follows the CG-1 south briefly before turning east onto a narrow road that becomes progressively steeper over its 12km length. The lower section passes through terraced stone walls and chestnut woodland at gradients between 6 and 8%; the middle section, from approximately 4km to 8km, reaches the defining 13.8% maximum on a series of tight hairpins above the Valira del Sud gorge; the upper section moderates to 7–9% through open pasture terrain as the col approaches. The Vuelta stage that finished here in 2015 saw the peloton shattered by the gradient, and the Strava segment from the Sant Julià junction to the summit remains one of the most competitive HC climb leaderboards in the principality.
Creu de Batlle, 6.8km at 7.6% average with ramps to 12%, is the south zone's second climb and one of the least-known ascents outside Andorra despite a gradient profile that rivals the best Category 1 climbs in Catalonia. Starting from 1,410m — already at altitude — and rising to 1,930m on a remote border road above the Spanish parish boundary, the climb passes through high-altitude forest before reaching open pasture terrain without road markings, distance signs, or tourist infrastructure of any kind. Its remoteness is the point: this is Andorra at its most raw, the country before the shopping centres and the ski lifts, a mountain road that exists because shepherds needed to move flocks and that has been sealed for cycling without losing its character of authentic isolation.

- Coll de la Gallina hosted a 2015 Vuelta a España summit finish. The southern zone is used by Andorra-based professionals for strength-building sessions on account of its gradient severity at lower altitude than the northern passes. The roads between Sant Julià de Lòria and the Spanish border are part of the standard professional training loop from Andorra la Vella south.

Best Time to Cycle in Southern Passes
The southern passes are accessible earlier than the northern HC climbs — Coll de la Gallina clears of winter conditions by late April in most years, and the lower start elevation of both climbs means cold temperatures are less of a constraint than at Arcalís or Envalira. May through September represents the full season; October is viable for fit, acclimatised riders but the higher reaches of Creu de Batlle above 1,800m can be cold and wet. The Gallina is a genuine all-day enterprise in terms of physical demand — plan accordingly in terms of nutrition and hydration, as services on the climb itself are non-existent.
Temperature: -5°C (winter) to 28°C (summer)
Insider Tips
- Coll de la Gallina is the most physically demanding climb in Andorra and should not be attempted until you have completed at least two full days of altitude acclimatisation. The 13.8% maximum gradient sections arrive at a point in the climb where accumulated fatigue from the lower slopes is already significant, and the thin air at 1,700–1,910m reduces power output by 8–12% compared to sea level. Riders who have not acclimatised will find themselves in difficulty at a point where there is no support, no café, and no quick descent route available.
- Creu de Batlle is the secret climb of Andorra — a genuine Category 1 ascent that appears on no "best of" list in English, receives perhaps 30 cyclists per week in peak season, and delivers a quality of Pyrenean mountain isolation that the more celebrated northern passes cannot match simply because of their fame and traffic. The road surface above 1,700m has some rough sections but is rideable on 25mm tyres without difficulty. If you can do only one "discovery" climb in Andorra beyond the headline passes, this is it.
- The Spanish border crossing at the foot of the approaches to Coll de la Gallina and in the wider southern zone involves no formality — the Schengen area means riders can cross freely. This opens practical route options: the road from La Seu d'Urgell in Spain to the Andorran border and then up to Coll de la Gallina effectively triples the climbing available on a single day by adding the approach from the Spanish valley floor, producing a 1,400m day of exceptional quality for strong riders.
How to Get to Southern Passes for Cycling
Nearest Airports
Barcelona El Prat Airport(BCN)
Transfer: 2 hours to Sant Julià de Lòria by car
The southern zone is the closest Andorran cycling area to Barcelona — entering Andorra via La Seu d'Urgell and the N-145, Sant Julià de Lòria is the first significant town encountered at the Spanish-Andorran border. The transfer is shorter than to Andorra la Vella and the border crossing is fast. Sant Julià is the natural base for Coll de la Gallina and Creu de Batlle without requiring navigation through the capital.
Toulouse-Blagnac Airport(TLS)
Transfer: 3 hours to Sant Julià de Lòria by car
Toulouse is a longer approach to the southern zone than Barcelona, requiring the full Andorra traverse from the French border at Pas de la Casa through Andorra la Vella and south to Sant Julià. The extra 30 minutes over Barcelona is partially offset by the quality of the Ariège valley approach road from Foix — one of the finest mountain drives in the French Pyrenees.
Getting around: Car Recommended — Sant Julià de Lòria, at 909m, is the practical base for the southern passes and has a small selection of hotels and restaurants serving the town's Andorran residents rather than a tourist trade. The CG-1 south from Andorra la Vella to Sant Julià carries moderate traffic on weekdays; cycling this corridor is manageable but the main road shoulder is narrow in places. The turn-off for Coll de la Gallina is 3km south of Sant Julià — from here the road is essentially traffic-free. Creu de Batlle is accessed via the southern parish of Sant Julià on a road that requires careful navigation on first visit; download the GPX in advance and confirm the route before departing the valley.
