1. Introduction to Pico Tesorero

Pico Tesorero (2,570 m / 8,432 ft) is one of the most recognizable peaks in the Picos de Europa National Park in northern Spain. While not the highest (Torre Cerredo holds that title), its distinctive pyramidal shape makes it a highly sought-after summit for hikers and mountaineers. Its name, which translates to "Treasurer's Peak," stems from a legend that treasure was hidden near its summit. The peak provides stunning panoramic views of the surrounding Central Massif (also known as "Urrieles") of the Picos de Europa.

2. Location and Geography

• Region: Asturias and Castilla y León, Spain
• Mountain Range: Picos de Europa (Central Massif or Urrieles Massif)
• Nearest Towns: Sotres, Bulnes, Espinama.
• Coordinates: 43°12′48″N 4°51′51″W
• Prominence: Relatively high within the Urrieles range, offering commanding views.
• Notable Features: Sharply defined pyramidal shape, rocky terrain, proximity to other iconic peaks like Torre Cerredo and Naranjo de Bulnes (Picu Urriellu).

3. Hiking Routes and Access

• General Difficulty: Strenuous. While not requiring technical climbing skills in good conditions, the ascent involves steep slopes, loose rock, and exposed sections. Experience in mountain hiking is essential.
• Best Time to Visit: July to September (summer months). Snow can linger at higher elevations well into the summer, and winter conditions are extremely dangerous. Check weather forecasts closely before departing.

• Starting Points & Route Options:

  • From Refugio de Urriellu (Naranjo de Bulnes): This is the most popular starting point. Reaching the Refugio requires a hike itself (typically 2-3 hours from the nearest road access). The route from the Refugio involves following marked trails and then scrambling over rocky terrain. Expect a full day hike (6-8 hours round trip) from the Refugio to the summit and back.

    • Accessing Refugio de Urriellu:
      • From Poncebos via the Canal del Texu: A very steep and classic but long hike through a river gorge. (Around 3 hours)
      • From Sotres via Pandébano and Collado Vallejo: A longer and less steep approach (around 4 hours)
      • Cable car from Fuente Dé to El Cable, then hike: This considerably shortens approach time, but requires a further hike (approx 2.5 - 3 hours)
  • From Collado Jermoso: A more challenging route, often involving traversing exposed ledges. Requires greater mountaineering experience.
  • From other Refugios (e.g., Refugio Vega de Urriellu): Several other refuges exist in the area and longer routes can be planned involving overnight stays in multiple refugios.

• Route Description (Typical Route from Refugio de Urriellu):

  1. Start at Refugio de Urriellu (1,960m).
  2. Follow the marked trail towards the base of Pico Tesorero.
  3. The trail becomes steeper and more rocky.
  4. Ascend a scree slope, carefully traversing towards the ridge.
  5. The final ascent to the summit involves scrambling over rocks, sometimes requiring the use of hands.
  6. Be cautious of loose rocks and exposure.
• GPS Tracks/Maps: Essential. Obtain accurate GPS tracks or topographic maps (IGN Spain maps are recommended) before your hike. Download offline maps to your smartphone or GPS device.
