Arista Mowgli

Pared de Bozuelo, Baños de Panticosa · Aragonese Pyrenees (Tena & Canfranc valleys) · Spain

Easy to bailBolting confidence: high

An easy granite ridge above the Bozuelo meadows, low-angled and never exposed. Two smooth friction slabs at 5a, on pitches 1 and 6, are the only real difficulties; the rest is steps and short walls at grade 3 to 4. Ideal for a first multipitch, and you can step off rightwards onto ledges almost anywhere.

The route

Overview

Seven short pitches up a low-angled granite ridge on the left of the Llanos de Bozuelo, on the way from Baños de Panticosa to the Bachimaña refuge. The difficulties are isolated: a smooth friction slab in the middle of pitch 1 and another at the start of pitch 6, both 5a and both well protected. Between them the ridge is stepped and easy. The opening team designed it as part of a way to climb, not walk, up to the Bachimaña refuge, linking the Vía del Nano, Espolón Rebollón, this ridge and the Espolón del Pino. It has 18 logged ascents on camptocamp and consistently good reviews.

PitchGradeLengthBoltsNotes
P15a30 m6 boltsA short wall of about 4 m with an awkward move, some 10 m of walking, then a smooth easy-angled slab with a thin friction move in the middle where you have to trust your feet. One writer suggests skipping the first little wall.
P24b30 m6 boltsSteps to a pine, which you use to get over the small roof above it (the 'pine move'). Then easy-angled steps to the belay.
P34a25 m4 boltsSteps, then a small slab after a pine. Belay at a pine.
P43a25 m3 boltsA small, easy-angled crest.
P53b25 m7 boltsSteps, left across an earthy gully, up a small slab, then a horizontal traverse left to the belay. One source gives 30 m.
P65a30 m6 boltsA fine smooth slab with friction moves at the start, very well protected, finishing up an unusual 'wrinkled' slab. Belay at a big pine, which is better for communication than the next belay 5 m further on (R6 bis).
P74c30 m4 boltsFrom R6 bis: a short vertical slab, easiest by its left edge, then an easy-angled friction slab with a small bulge and a last slab to the final belay at a pine.

Getting there

Approach

To the parking

Base is Baños de Panticosa (Balneario de Panticosa, about 1,640 m) at the head of the Tena valley. Park near the Casa de Piedra refuge; parties in 2024 report no trouble parking there.

On foot · about 40 min

35 to 45 min. Take the GR11 behind the Casa de Piedra refuge towards the Bachimaña refuge. After about 15 min you pass one of the Caldarés waterfalls; another climb brings you to the flat Llanos de Bozuelo. The ridge is clearly visible on the left. Follow cairns to its base, where a cairn marks the start.

Getting down

Descent

From the last belay follow the cairns to the right. A good path reaches the GR11 in about 10 min, above the Llanos de Bozuelo. Allow about 40 min back to the car park.

Retreat

Bailing off the route

Easy to bail

A Basque guide blog notes that you feel you could abandon the route at any moment by using the terraces and gullies on the right. The ridge is low-angled and never exposed, and the pitches are 25 to 30 m between bolted or tree belays.

Retreat from
Almost any belay, by walking or scrambling off right onto the ledges and gullies.
Point of no return
None.
Carry
Nothing special; a 50 m rope if you prefer to abseil a pitch (not described).
Basis
Stated in the sourcesThe Eskalatzencas description states the escape options; the detail of the ground on the right is not described further.

Safety

Hazards

  • The 5a friction slabs feel hard for the grade to people not used to granite: 'quite cheeky for 5a' in one 2023 report.
  • Some belays are on trees.
  • A July 2026 party noted fine weather turning stormy during the day; start early in summer.

Sun and weather

Conditions

South-east facing at 1,850 to 2,050 m. A summer route: reports run from early July to early October. Friction slabs, so wait for dry rock.

What to carry

Gear

Camptocamp says a 50 m rope and 8 quickdraws plus belay gear, including two 60 cm slings to reduce drag. A Basque guide blog says 7 quickdraws; a 2023 party found 5 enough. Cams and nuts are not needed. Slings for the pine belays.

Worth knowing

Tips

  • Allow 1.5 to 2 hours; fast parties link it into two or three long pitches.
  • Climbed in approach shoes by confident parties.
  • Popular combinations: Vía del Nano and Espolón Rebollón first, or Lady Lister before and the Mur de la Cascade de Bachimaña after.
  • Make the belay at the big pine at the end of pitch 6 so you can hear each other.

Open questions

Where sources disagree

  • Name: spelled Mowgli, Mogli and Mogly in different sources.
  • Pitch lengths: camptocamp gives 25 m for pitch 5 and 30 m for pitch 6; the Eskalatzencas blog gives 30 m and 25 m.
  • Quickdraws: 8 (camptocamp), 7 (Eskalatzencas), 5 (a 2023 report).
  • Approach: 45 min (camptocamp), 35 to 40 min (Eskalatzencas), 30 to 40 min in reports.

Vía del Ibón

A mountain-style line on dark, weathered granite twenty-five minutes above the spa of Baños de Panticosa. It links ramps, a short overhanging break, slabs and a rounded boulder, with one well-bolted 5c move and the rest 4b to 5b. The rock between the good sections is earthy and lichenous, but the friction is excellent and the bolting generous.

Switzerland · Wiwanni (Baltschiedertal)

Salamander

Eight short pitches of 4b to 5a on compact, grippy gneiss slabs above the Wiwannihütte, finishing on a 2880 m summit. Pitches 3 and 4 climb a big steep slab that is the heart of the route. Chained belays and an abseil descent make it the gentlest introduction to the Wiwanni routes, though the starting pitches feel stiff for 4b.

A short, friendly pillar of wonderfully rough, sculpted limestone above a Pyrenean village, bolted in 2022 as a first multipitch. Five pitches of grade 3 and 4 with single moves of 5a (4c obligatory), fifteen minutes from the car. Ideal for learning rope work; experienced parties move together and are up in an hour.
