Peña Ten Circular Trail

This trail is considered difficult, requiring a very good physical condition, firm footing, and experience in high-altitude mountain environments. It's rated as a "demanding hiking trail (T3)" due to significant ascents and descents, steep slopes, and varied terrain.

The route is approximately 13.6 km (8.5 miles) long with an elevation gain of about 912 meters (2,992 feet). Komoot estimates the duration to be around 5 hours and 52 minutes, but actual time can vary based on fitness level and breaks.

The circular hike starts from Fuente La Turriente. While the exact parking situation isn't detailed, it's generally assumed that trailheads like this have some form of parking available nearby for hikers.

The terrain is varied and challenging. You'll encounter forest tracks, established paths, and off-trail sections ("campo a través"). Expect steep ascents and descents, green meadows, beech forests (hayedos), and scree slopes (pedreras). The descent from Peña Ten can be particularly challenging with loose stones, potentially requiring some scrambling.

The trail offers spectacular panoramic views. Highlights include the summit of Peña Ten itself, offering 360-degree vistas of the Picos de Europa and Cantabrian Mountains. You'll also pass the View of the Picos de Europa from Collada de las Arriondas and ancient Centenary Oaks. The route traverses traditional mountain landscapes, glacial cirques, and lush forests.

The best time to hike Peña Ten is typically during the warmer months, from late spring to early autumn, when the weather is more stable and snow has melted from higher elevations. Always check the weather forecast before you go, as mountain conditions can change rapidly.

While specific dog regulations for this exact trail are not provided, the route passes through both Parque Natural de Ponga and Parque Regional de la Montaña de Riaño y Mampodre. Generally, dogs are allowed in Spanish natural parks but must be kept on a leash to protect wildlife and livestock. Always verify local regulations before bringing your dog.

Typically, there are no entrance fees for hiking in Spanish natural or regional parks like Parque Natural de Ponga or Parque Regional de la Montaña de Riaño y Mampodre. However, certain activities or access to specific restricted areas might require permits. For general hiking on established trails, permits are usually not necessary, but it's always wise to check with local park authorities for any specific requirements.

Yes, the route also passes through sections of the Puerto de Ventaniella and the Camino a la Hayona de Valdosín. For those seeking a longer adventure, the route can be extended to visit the historic vega and hermitage of Arcenorio or to ascend Pileñes (2,019 m), a nearby sister peak.

Given the trail's difficulty and high-altitude environment, you should pack appropriate gear. This includes sturdy hiking boots with good ankle support, layers of clothing suitable for changing mountain weather, rain gear, plenty of water and snacks, a map and compass or GPS device, a first-aid kit, and sun protection. Trekking poles are highly recommended for stability on steep and loose terrain.

Peña Ten offers a unique experience due to its strategic location directly on the border between León and Asturias, allowing hikers to cross between these two autonomous communities. It's also the highest peak within the Parque Natural de Ponga and is recognizable by its "pyramidal profile" and "isolated character," providing unobstructed 360-degree views from its summit.
