The GR2 Trail is one of Spain’s most ambitious long-distance walking routes, a staggering 870-kilometre odyssey that cuts a definitive line through the heart of Catalonia. Stretching from the high, jagged peaks of the Pre-Pyrenees to the sun-drenched Mediterranean hinterlands, this trail offers a profound immersion into the diverse landscapes, ancient cultures, and rugged topography of northeastern Spain. Unlike shorter, more commercialised routes, the GR2 is a journey of endurance and discovery, requiring between 45 and 55 days to complete in its entirety. It is a path that transitions from the alpine majesty of the Berguedà region, through the volcanic scars of La Garrotxa, across the rolling central plateaus, and eventually towards the coastal sierras that overlook the Balearic Sea.
With a cumulative elevation gain of approximately 12,400 metres, the GR2 is classified as a moderate but physically demanding undertaking. It does not rely on extreme technical climbing, but rather on the sheer persistence required to traverse hundreds of kilometres of varying terrain. Walkers will find themselves navigating limestone ridges, ancient Roman roads, medieval mule tracks, and dense forests of cork oak and beech. The trail is a masterclass in geographical transition, where the crisp, thin air of the mountains gradually gives way to the humid, herb-scented breezes of the Mediterranean. It is a route designed for those who seek to understand the soul of a region through the rhythm of their own footsteps, moving far beyond the tourist hubs of Barcelona into the silent, stone-built villages where time appears to have slowed to a crawl.
The GR2 Trail is more than just a hiking path; it is a geographical narrative of Catalonia. The journey begins in the shadow of the iconic Pedraforca mountain, a twin-peaked massif that serves as a beacon for Catalan mountaineers. From the trailhead at Refugi d'Estasen, the route plunges into a landscape defined by dramatic limestone escarpments and deep, forested valleys. This initial section sets the tone for the first two weeks of the trek, where the elevation remains high and the weather can be temperamental. As the trail progresses eastward and then southward, the high-alpine character softens into the unique volcanic landscape of the Garrotxa Volcanic Zone Natural Park. Here, walkers traverse over forty dormant volcanic cones, their slopes now covered in lush vegetation and the famous Fageda d'en Jordà beech forest, which grows on a prehistoric lava flow.
The middle section of the GR2 explores the "Catalunya Central," a region of high plateaus (altiplans) and deep river gorges. This is the agricultural and spiritual heartland of the region, where the trail passes through historic towns like Vic, known for its medieval centre and vibrant markets. The terrain here is undulating, offering wide-open vistas across the Plana de Vic towards the distant, serrated silhouette of the Montserrat massif. The physical challenge of the GR2 lies not in individual steep climbs, but in the cumulative fatigue of daily 20-kilometre stages. The path is well-marked with the characteristic red and white blazes of the Grande Randonnée network, yet it retains a sense of wildness, particularly in the remote sections of the Collsacabra and the Guilleries mountains.
As the trail nears its final third, the influence of the Mediterranean becomes undeniable. The vegetation shifts from deciduous beech and oak to evergreen holm oak, pine, and aromatic shrubs like rosemary and thyme. The air becomes warmer, and the light takes on the golden, hazy quality typical of the Spanish coast. The final descent towards the terminus involves navigating the coastal ranges, where the trail offers occasional glimpses of the sea from high ridgelines. Throughout the 870 kilometres, the GR2 maintains a balance between natural solitude and cultural connection, ensuring that every few days, walkers descend into a village to resupply, share a meal of local "botifarra" and beans, and experience the legendary hospitality of the Catalan countryside.
The GR2 Trail follows a network of paths that have existed for millennia. Many segments of the route are built upon "Camins de Transhumància"—ancient seasonal migration routes used by shepherds to move livestock between the high mountain pastures of the Pyrenees in summer and the warmer lowland plains in winter. These paths were the lifelines of rural Catalonia, facilitating not only the movement of animals but also the exchange of news, goods, and culture between isolated mountain communities. Walking the GR2 is, in many ways, an act of historical preservation, as modern hikers keep these traditional thoroughfares alive in an era of high-speed rail and motorways.
The cultural heritage along the trail is immense. The route passes through numerous medieval villages, such as Santa Pau and Rupit, where the stone architecture has remained largely unchanged for centuries. These towns were often fortified during the Middle Ages, serving as defensive outposts during the various conflicts that shaped the Iberian Peninsula. The trail also intersects with significant religious history; the presence of Romanesque hermitages and grand monasteries, such as the Monastery of Sant Joan de les Abadesses, highlights the spiritual importance of these mountains during the 10th to 12th centuries. These structures, often perched on seemingly inaccessible crags, provided sanctuary for monks and travellers alike and remain some of the finest examples of Romanesque art in Europe.
In the 20th century, the GR2 was formalised as part of the European long-distance path network. The "Senderos de Gran Recorrido" (GR) system was established in Spain in the 1970s, inspired by the French hiking tradition. The Federació d'Entitats Excursionistes de Catalunya (FEEC) has been instrumental in waymarking and maintaining the GR2, ensuring that it remains accessible to a global audience. Today, the trail stands as a symbol of Catalan identity, connecting the rugged independence of the mountain regions with the cosmopolitan energy of the lowlands. It is a route that honours the labour of the past—the stonemasons, the shepherds, and the charcoal burners—while providing a modern sanctuary for those seeking to reconnect with the natural world.

Timing is the most critical factor when planning an 870-kilometre trek across Spain. The GR2 traverses regions with vastly different microclimates, from the sub-alpine conditions of the Berguedà to the Mediterranean heat of the south. Consequently, the "best" time to walk is a compromise between avoiding deep snow in the mountains and escaping the oppressive heat of the plains.
Spring (April to June): This is arguably the most spectacular time to experience the GR2. In the high sections, the snow begins to melt, feeding crystal-clear streams and waterfalls. The meadows are carpeted in wildflowers, including wild narcissus and gentians. Temperatures are generally mild, ranging from 10°C to 22°C, making for comfortable walking conditions. However, late spring can bring "tempestes de tarda" (afternoon thunderstorms), particularly in the mountains, so hikers must be prepared for sudden downpours.
Autumn (September to October): Autumn offers a different but equally beautiful palette. The beech forests of La Garrotxa and Collsacabra turn vibrant shades of copper, gold, and ochre. The air is often crisper and clearer than in summer, providing the best long-distance views. This is also the season of the "caçadors de bolets" (mushroom hunters), a deeply ingrained Catalan tradition. The temperatures are stable, though the days begin to shorten significantly by late October. This is the ideal window for those who prefer cooler weather and the dramatic colours of the changing forest.
Summer (July to August): Walking the GR2 in mid-summer is not recommended for the faint-hearted. While the high-altitude sections near Berga remain pleasant, the lower plateaus and coastal ranges can experience temperatures exceeding 35°C. Water sources in the central and southern sections may dry up, and the risk of forest fires often leads to the closure of certain trail segments. If you must walk in summer, an extremely early start (05:00) is essential to finish the day's stage before the midday heat becomes dangerous.
Winter (November to March): Winter transforms the northern sections of the GR2 into a serious mountaineering prospect. Snow can block the passes near Refugi d'Estasen, and many high-altitude refuges operate on a limited basis or require advanced booking for heating. Conversely, the southern sections of the trail can be quite pleasant in winter, with daytime temperatures around 12-15°C, though nights are cold. A full winter traverse requires specialised equipment and advanced navigation skills.
Given the 870 km length, this itinerary is broken into eight major stages. Most walkers will take 45 to 55 days, including rest days in major towns.
Stage 1: The Pre-Pyrenean Highs (Days 1–7)
Stage 2: The Volcanic Heart (Days 8–14)
Stage 3: The Collsacabra Escarpments (Days 15–21)
Stage 4: The Central Plateaus (Days 22–28)
Stage 5: The Holy Mountain (Days 29–35)
Stage 6: The Wine Country (Days 36–42)
Stage 7: The Southern Sierras (Days 43–48)
Stage 8: The Final Descent (Days 49–55)
Important Notes:
Preparing for an 870-kilometre walk requires a different mindset than a weekend trek. Physical fitness is paramount; you should be comfortable walking 20-25 kilometres per day with a 12-15 kg pack for multiple consecutive days. Training should focus on leg strength and cardiovascular endurance, ideally on varied terrain similar to the Catalan hills. Logistics are the second pillar of preparation. You must coordinate your start date with the seasonal weather windows and ensure you have a strategy for resupplying food and water.
Barcelona serves as the primary international gateway. From Barcelona, you can take a Renfe train or an ALSA bus to Berga. From Berga, local taxis or occasional shuttle services can take you to the Refugi d'Estasen trailhead. It is wise to spend a night in Berga to finalise your gear and buy your initial food supplies. Ensure you have a "Credencial" or a hiking log if you plan to stay in certain pilgrim-style hostels, though the GR2 is less formalised than the Camino de Santiago.
The GR2 offers a mix of accommodation types, reflecting the diverse regions it traverses. In the northern mountains, you will primarily rely on "Refugis" (mountain huts). As you move into the central and southern areas, you will stay in "Hostals" (small guesthouses), "Turisme Rural" (farmstays), and occasional campsites.
Mountain Huts (Refugis): These are often managed by the FEEC. They provide dormitory-style sleeping, communal meals, and basic washing facilities. Booking in advance is essential, especially on weekends. Most provide blankets, but a silk liner or light sleeping bag is required. Costs range from €15 to €25 for a bunk, with "mitja pensió" (half board) costing around €45-€55.
Village Accommodation: In towns like Olot, Vic, and Vilafranca, you will find a range of hotels and pensions. These offer a chance for a private room, a hot shower, and laundry facilities. Prices vary widely but expect to pay €40-€70 for a mid-range room.
Camping: Wild camping is generally restricted in Catalonia, especially in Natural Parks. However, there are official campsites along the route, particularly near the coast and in the Garrotxa region. If you plan to camp, ensure your tent is lightweight and has good ventilation for warm nights.
One of the great advantages of the GR2 Trail is that no formal permits are required to walk the route. The trail is public and open to all. However, there are specific regulations you must follow, particularly when passing through Natural Parks such as the Garrotxa Volcanic Zone, Sant Llorenç del Munt i l'Obac, and Montserrat.
Natural Park Regulations:
Hut Bookings: While not a "permit," booking your spot in the FEEC refuges is essential. During the peak months of May, June, and September, the huts can fill up weeks in advance, especially on Friday and Saturday nights. You can book most Catalan refuges through the central portal at refugis.cat. If you are a member of a mountaineering federation (like the BMC or AAC), bring your card to receive a discount on hut fees.
Hunting Season: Be aware that hunting is a popular activity in rural Catalonia, typically from September to February. While the GR2 remains open, it is advisable to wear bright clothing (high-visibility orange or yellow) when walking through forested areas during these months, especially on Thursdays and Sundays.

If you have extra time before or after your 870 km journey, Catalonia offers a wealth of experiences:
Weather Extremes: The primary safety concern on the GR2 is the weather. In the northern sections, hypothermia is a risk even in spring if you are caught in a cold rainstorm at altitude. Conversely, heatstroke and dehydration are genuine threats in the central and southern sections. Always check the local forecast via "Meteocat" (the Catalan meteorological service) before starting your day.
Water Scarcity: In the limestone regions and the southern sierras, natural water sources are rare. Never pass a reliable fountain (font) without topping up your bottles. In summer, carry a minimum of 3-4 litres if you have a long stage between villages.
Terrain and Navigation: While the GR2 is well-marked with red and white paint, markers can be obscured by vegetation or lost during forestry work. Always carry a GPS backup. Some sections involve walking on narrow ridges or steep scree slopes; take your time and use trekking poles for stability.
Wildlife: Wild boars (senglars) are common throughout Catalonia. They are generally shy but can be aggressive if they have young or feel cornered. Keep your food sealed and never feed them. Ticks are also present in long grass and ferns; perform a daily tick check on your body.
Emergency Services: The emergency number in Spain is 112. Mobile signal is generally good in the villages but can be non-existent in deep gorges or remote mountain sections. Consider carrying a satellite messenger (like a Garmin inReach) for a trek of this length.
Pedraforca Ascent: Before starting the GR2 at Refugi d'Estasen, many hikers take a day to summit Pedraforca (2,506 m). It is a challenging scramble but offers the most iconic view in the Catalan Pre-Pyrenees. The "Enforcadura" (the notch between the two peaks) is a classic destination.
The Submerged Church of Sant Romà de Sau: When the water levels of the Sau Reservoir are low, the 11th-century Romanesque church of Sant Romà emerges from the depths. It is a haunting and beautiful sight, easily accessible via a short detour from the main trail.
Castellfollit de la Roca: A spectacular village built on a narrow basalt crag, over 50 metres high and nearly a kilometre long, formed by the erosion of two rivers against ancient lava flows. The GR2 passes nearby, and the detour into the village is highly recommended for photography.
The Hermitages of Montserrat: While the main Abbey is famous, the real magic of Montserrat lies in the scattered ruins of ancient hermitages hidden among the rock spires. A few hours spent exploring the paths above the monastery will lead you to silent, spiritual places with incredible views.
The Roman Ruins of Olèrdola: Located in the Penedès region, this strategic hilltop has been occupied since the Bronze Age. You can see Roman walls, a medieval castle, and rock-cut tombs, all while overlooking the vineyards you will walk through the following day.
The GR2 passes through some of the most ecologically sensitive areas of Spain. As a long-distance walker, your cumulative impact over 50 days can be significant. Adhering to Leave No Trace principles is essential to ensure the trail remains pristine for future generations.
