How to Hike the Ruta del Cares Trail, Spain: Map, Instructions, and Tips for 2025

The Ruta del Cares, often called the “Divine Gorge,” is one of Spain’s most spectacular hiking trails, winding through the heart of Picos de Europa National Park.

Known as PR-PNPE 3, the trail’s dramatic scenery and moderate difficulty make it a bucket-list adventure for hikers worldwide. In 2025, with improved access and sustainable tourism measures, it’s the perfect time to explore this iconic route. This 2,000-word guide, informed by sources like Anywhere We Roam, Spain.info, and posts on X, provides a detailed map, step-by-step instructions, safety tips, and practical advice for hiking the Ruta del Cares. Whether you’re a seasoned trekker or a first-time visitor, here’s everything you need to plan an unforgettable journey.

Why Hike the Ruta del Cares?

The Ruta del Cares is a marvel of nature and engineering, originally built between 1916 and 1921 to maintain a hydroelectric canal and later expanded in the 1940s. Stretching along a gorge flanked by 2,000m cliffs, it’s dubbed “La Garganta Divina” for its awe-inspiring beauty. Lonely Planet calls it “one of Spain’s most arresting trails,” while X user @TravelSpain enthuses, “The views from Ruta del Cares are unreal—worth every step!” With minimal elevation gain (200m), the trail is accessible yet thrilling, passing through tunnels, over bridges like Puente de Los Rebecos, and alongside mountain goats. Its 300,000 annual visitors attest to its popularity, yet strategic planning ensures a serene experience. This guide covers the standard 22–24km out-and-back hike, with options for shorter or one-way treks.

Is the Ruta del Cares Safe in 2025?

Spain ranks 29th in the 2024 Global Peace Index, and Picos de Europa is a low-crime area, making the trail safe for hikers. The U.S. State Department rates Spain as Level 2 (exercise increased caution) due to general tourism risks like pickpocketing, but no specific concerns apply to this remote region. The trail itself poses moderate risks: uneven terrain, narrow sections (1–3m wide), and sheer drop-offs without guardrails. Anywhere We Roam notes it’s “safe with caution, even for those with mild vertigo.” X user @HikeEurope advises, “Stick to the wall side and watch your step—gorgeous but no place for distraction.” Recent trail maintenance and regulated parking enhance safety.

Key Safety Tips

Terrain Awareness: Rocky paths and polished surfaces can be slippery when wet. Wear sturdy hiking boots with good grip.
Weather Preparedness: Weather shifts rapidly (5–25°C in spring/fall; hotter in summer). Pack a waterproof jacket and warm layers. Avoid hiking during heavy rain or snow due to rockfall risks.
Vertigo Caution: Narrow sections with 500m drops may unsettle those with height fears. Walk close to the cliff wall.
Emergency Prep: Mobile coverage is spotty; carry a charged phone for 112 (emergency service). Inform someone of your plans.
Hydration and Nutrition: No facilities exist on the trail. Bring 2L water and high-energy snacks (nuts, bananas).
Group Hiking: Solo hiking is fine, but groups enhance safety. Guided tours via Frontera Verde ($50–$80) offer expert support.

Los Collaos: Highest point, 3km from Poncebos, with views of Mount Urriellu.
Bolín Bridge: 8km from Poncebos, 60m long, crossing the river.

Navigation Tip: The trail is clear and impossible to lose, per Moonhoneytravel. Carry a map (AllTrails or Komoot) for reference, as mobile signal is weak.

Step-by-Step Hiking Instructions

Starting from Poncebos (Recommended)

Preparation: Arrive by 8 AM to secure parking or take the shuttle. Pack 2L water, snacks, sunscreen, and a raincoat. Wear hiking boots.
Trailhead: From Poncebos, walk 10 minutes along the main road (AS-264), keeping the Cares River on your left. Pass Puente La Jaya (leads to Bulnes; ignore). At the information booth, turn right onto the signed “Senda del Cares / Caín” path (PR-PNPE 3).
First 2km (0–45 min): Ascend a steep, cobbled path (200m gain) through rocky terrain. Pass a falling rocks sign. Views of limestone peaks emerge. Pace yourself; this is the toughest section.
2–8km (45 min–2h): The trail levels at Los Collaos, offering panoramic views. Follow the flat, 1–3m-wide path carved into cliffs. Pass small caves and the canal (non-drinkable water). Spot goats and vultures. The gorge widens, with Mount Urriellu visible on clear days.
8–12km (2–3.5h): Cross Bolín Bridge (60m), then Los Rebecos Bridge. Enter tunnels (some wet; watch your head). The gorge narrows, with waterfalls and greenery. Descend slightly to Caín, arriving at the village’s gorge entrance.
In Caín: Rest at cafes (try cachopo, $10–$15) or dip in river pools (cold!). For round-trip, retrace steps (2.5–3h back, faster downhill). For one-way, arrange a taxi/4×4.
Return (Round-Trip): The return feels easier, with new perspectives. Start back by 3 PM to finish before dark. Total: 6–7h.

Starting from Caín (Alternative)

Why Choose Caín?: Narrower gorge, more tunnels/bridges, and fewer hikers early, per Roads-and-Rivers. Ideal for shorter hikes (e.g., 4–6km out-and-back).
Instructions: Park in Caín by 8 AM (easier than Poncebos). Start at the gorge entrance. The trail is flat, following the river closely. Pass tunnels and Los Rebecos Bridge early. Turn back at Culiembro (hut, 5km) for a shorter hike or continue to Poncebos (3–3.5h). Return or book transport.
Note: Caín’s section is more dramatic but less accessible by public transport.

Must-Know Trail Highlights

Puente de Los Rebecos: A green bridge at 8.4km, framed by cliffs, is Instagram-famous. Much Better Adventures calls it “northern Spain’s most photographed spot.”
Tunnels and Caves: Near Caín, 71 hand-carved tunnels add adventure. Some drip water; bring a headlamp for fun.
Mountain Goats: Friendly goats roam cliffs, unbothered by hikers. Keep distance to avoid rockfalls.
Los Collaos Viewpoint: At 3km from Poncebos, spot Mount Urriellu (Naranjo de Bulnes), a 500m climbing icon.
Cares River: Its turquoise waters, 500m below, create a hypnotic backdrop. Spain.info highlights bridges like Bolín for dizzying views.
