What to Do in the Aragonese Pyrenees and Jaca (Beyond the Ski Slopes)

Updated: 5 days ago

The Aragonese Pyrenees are where serious skiers and adventurous families go when they want real mountains without the crowds. Formigal is the crown jewel -- the largest ski resort in Spain -- but Astun, Candanchu, and the quieter Panticosa round out a region that offers something for every level. And beyond the ski runs, you have medieval Jaca, the ghostly Canfranc train station, and some of the most dramatic gorge country in Europe.

This region rewards the curious. Here is how to make the most of it.

Ski Tours and Guided Runs

Formigal alone has over 140 kilometers of marked runs. Hiring a local guide is the best way to unlock the mountain -- whether you are a first-timer or chasing off-piste lines.

Formigal: Group and Private Ski Lessons

Formigal's ski school is well organized, with English-speaking instructors available. Private lessons are worth it if your group has mixed ability levels -- instructors can tailor the pace and terrain.

Astun and Candanchu: Family Ski Days

Astun and Candanchu sit side by side near the French border and are fantastic for families. Astun has a gentler learning area and excellent beginner slopes. Candanchu is the oldest ski resort in Spain and has serious character -- old stone buildings, a classic mountain-village feel, and surprisingly good terrain for intermediates.

Portalet: Backcountry Ski Touring

For experienced skiers, the Portalet pass area and the slopes leading into France are prime ski touring territory. The high-altitude snowpack stays reliable well into spring. Always go with a certified mountain guide -- the terrain is serious and conditions change fast.

Medieval Jaca: The Heart of the Aragonese Pyrenees

Jaca is the base camp for most visitors to the Aragonese Pyrenees, and it has much more to offer than a place to sleep. This is one of the oldest cities in the medieval kingdom of Aragon, and it wears its history well.

The Citadel of Jaca

The 16th-century pentagonal citadel is one of the best-preserved Renaissance military fortifications in Europe. It is still an active military facility, so access is by guided tour -- worth scheduling ahead.

Tapas and Local Food in Jaca

The tapas culture in Jaca is lively -- especially after a ski day. The calle Mayor and the streets around the cathedral fill up in the evenings with locals doing the ronda de pinchos. Chistorra sausage, ternasco lamb, and locally cured meats are the things to try.

Canfranc: The Abandoned Station That Survived

About 30 minutes from Jaca, the Canfranc International Railway Station is one of the most dramatic places in Spain -- a massive Belle Epoque station built in 1928 that once connected France and Spain by rail. It was abandoned in 1970 after a bridge collapsed on the French side and has been slowly crumbling (and equally slowly being restored) ever since.

The station is now a luxury hotel in one wing and a museum in the other. Even if you do not stay there, the guided history tours are excellent -- the story involves gold smuggled from Nazi Germany, secret wartime intelligence operations, and decades of political battles over its restoration.

Hecho and Anso: The Wild Western Valleys

Most visitors never make it to the Hecho and Anso valleys, which is exactly why you should go. These are among the least-visited valleys in the Pyrenees -- traditional stone villages, dialects (Benasque Pyrenean) still spoken by older residents, and wilderness that feels genuinely remote.

Snowshoeing in the Selva de Oza

The Selva de Oza forest in the Hecho valley is a winter wonderland on snowshoes. The trail through the beech and silver fir forest following the Aragon Subordan river is accessible to most fitness levels and spectacularly beautiful after a snowfall.

Canyoning and Nature in Spring

Come spring, the meltwater turns these valleys into canyoning paradise. The Boca del Infierno gorge near Hecho and the Foz de Biniés near Anso are two of the best in the region -- dramatic limestone walls, cold green water, and rappels that will be talked about long after the trip.

What to Wear

Pack for cold, wet conditions and dress in layers. The Aragonese Pyrenees sit at serious elevation -- Formigal's top runs are above 2,250 meters -- and the wind can make it feel much colder than the thermometer reads.

Base layer: Merino wool or synthetic thermal top and bottom. Skip the cotton entirely.

Mid layer: Fleece or softshell jacket for warmth that breathes.

Outer layer: Waterproof ski jacket and pants. Rentals are available at all resorts if you do not want to travel with bulky outerwear.

Footwear: Ski boots are rented at the resort. For village walking, bring insulated waterproof boots with grip -- Jaca streets get icy.

Extras: Helmet (required for children at most Spanish resorts, strongly recommended for adults), goggles, UV-blocking lip balm and sunscreen -- the sun at altitude is intense even on cold days.

Practical Tips

Getting here: Jaca is about 1.5 hours from Zaragoza and 4 hours from Barcelona or Madrid. A rental car is essentially required -- public transport to the ski resorts is limited.

Best months for skiing: December through March. Formigal typically has the best snow reliability in the Spanish Pyrenees thanks to its north-facing slopes and altitude.

Book ahead: Spanish school holidays (particularly Semana Blanca in February) fill up the resorts and lodging fast. Book 6-8 weeks ahead if your dates overlap.

Three-day itinerary idea: Day 1: Arrive Jaca, afternoon walk through old town, dinner on calle Mayor. Day 2: Full ski day at Formigal or Astun. Day 3: Morning at Canfranc station, afternoon drive through Hecho valley, return to Jaca.

Language: Spanish works everywhere. Some locals also speak Aragonese or French -- you will be warmly received either way.

When to Visit the Aragonese Pyrenees: A Seasonal Guide

The Aragonese Pyrenees are a mountain destination in every season, not just winter. Jaca is a proper medieval city that operates year-round, the gorges and river valleys of the region are best in spring and autumn, and the ski resorts at Formigal, Astun, and Cerler anchor a winter season that runs from November through April. Here is what each season looks like.

Winter (December -- April): Ski Season

The Aragonese Pyrenees receive the most Atlantic snowfall of any ski region in Spain. The Somport and Portalet passes channel moisture-laden air from the Bay of Biscay directly onto the main ridge, producing reliable and often heavy snowfall from December through March. Formigal's season is one of the longest and most consistent in the country, regularly running from late November through late April, with peak conditions in January and February when base snow depths on the upper mountain can exceed 2 meters.

Jaca, the natural base city for the region, sits at 820 meters in the Aragon river valley and receives significantly less snow than the resorts above. This makes it a practical base even in mid-winter -- accommodation, restaurants, and the city's medieval center are all fully accessible regardless of conditions on the mountain. The drive from Jaca to Formigal takes about 45 minutes on well-maintained road; Astún and Candanchú are closer, about 30 minutes on the road to the Somport tunnel.

Spring (April -- June): Canyons and River Valleys

Spring in the Aragonese Pyrenees belongs to the river valleys. The Ordesa and Monte Perdido National Park is at its most dramatic in May and June, when snowmelt fills the Arazas river and the waterfalls -- particularly the Cola de Caballo at the head of the Ordesa valley -- are running at their most powerful. The canyon walls of Ordesa are sheer and theatrical, and the main valley trail is manageable for reasonably fit hikers without technical equipment.

The Hecho, Ansó, and Benasque valleys are also excellent in spring. Wildflowers carpet the high meadows by late May, and the beech forests in the western valleys are especially beautiful when the new leaves are out in early May. May and June are genuinely among the best months to visit the Aragonese Pyrenees if outdoor activities beyond skiing are your priority -- trails are clear at lower elevations, the light is long and gentle, and the summer crowds have not yet arrived.

Summer (July -- August): High Mountain Season

July and August open the high mountain trails and refugios of the Aragonese Pyrenees fully. The GR11 long-distance trail crosses the region from east to west, and the section through the Benasque valley and over into the Ordesa area is one of the most spectacular multi-day hiking routes in Spain. The Aneto summit (3,404 m, the highest point in the Pyrenees) is approached from Benasque and is a challenging but non-technical ascent that draws serious hikers from across Europe. Book refugio beds in advance for any overnight route in July and August -- they fill quickly.

Afternoon thunderstorms are a summer reality in the Pyrenees. The standard advice applies: start hikes early, be off exposed ridges by early afternoon, and carry a waterproof layer even on days that start perfectly clear. The storms pass quickly but can be intense, with lightning over exposed terrain above 2,500 meters.

Autumn (September -- October): Beech Forests and Quiet Trails

Autumn is the best-kept secret of the Aragonese Pyrenees. The beech forests in the Hecho and Ansó valleys turn brilliant gold and amber in October, the mountain huts close for the season but the trails are still open and dry, and the region empties of summer visitors almost overnight after the first week of September. Temperatures are mild by day and cool by night -- ideal walking conditions -- and the gorges and river valleys are at their most photogenic under autumn light.

Jaca runs its annual medieval market and several autumn festivals through October, and the city's restaurant scene takes on a more local character once the summer tourism season winds down. If you want to experience the Aragonese Pyrenees as the people who live there experience them, September and October are the months to do it.
