Spain / Aragón
Ordesa · Cola de Caballo
Ordesa rewards a slow reveal: woodland beside the Arazas gives way to cascades, then the valley opens into the meadows of Soaso and the Cola de Caballo waterfall.
SENDA / PYRENEES
Hiking routes in the Pyrenees
When choosing a Pyrenees walk, compare distance, accumulated ascent and time for the same route variant. Different starting points, terrain and return routes can make for very different days at the same destination.
SENDA covers a selection of routes in Spain, France and Andorra, with gaps across the range. Montserrat has a separate directory as a Catalan massif outside the Pyrenees.
Use the filters to narrow your options, then open a guide to check the route variant, sources and visiting conditions. Inclusion in this directory does not confirm that a route is open.
How to compare the routes
| Criterion | What to check in the route guide |
|---|---|
| Area and starting point | Country and region narrow down the area. Check the actual trailhead and how to reach it; several itineraries may lead to the same lake or summit. |
| Variant and distance | Check whether the distance covers one way, an out-and-back or a full circuit. A point-to-point walk needs a plan for getting back from a different finish. |
| Accumulated ascent | This adds up every climb along the route. Read it alongside distance to compare effort; summit altitude is a separate measurement. Unconfirmed ascent remains unknown. |
| Walking time and the whole day | Check what the estimate includes and whether it covers the return. Allow extra time for stops, travel and any transport needed to reach the trailhead. |
| Terrain and difficulty | A short walk may still involve steep slopes, rock or exposed sections. SENDA’s labels give a broad indication for snow-free conditions and are not official technical grades. |
| Season and access | The suggested season helps with planning; it does not guarantee a snow-free trail or access on your chosen day. Check the forecast and notices from the managing body linked in the guide. |

Selva de Irati · Zabaleta
Irati reveals a different Pyrenean landscape, with the forest taking the role usually played by summits.
France / Occitanie
Lac de Gaube
Gaube compresses the transition from woodland to open mountain scenery into a relatively short outing.
France / Occitanie
Néouvielle · Aumar & Aubert
Néouvielle is a strong choice for a day among lakes, granite slabs and mountain pines.
France / Occitanie
Bouillouses · Lacs du Carlit
Bouillouses lets you plan a lake-focused day without making the Carlit summit compulsory.
France / Occitanie
Lac d’Oô
Oô has a clear visual story: a woodland climb ends with water and a tall waterfall across the lake.
Andorra / Ordino
Estanys de Tristaina
Tristaina is a useful introduction to Andorra’s lakes: three bodies of water sit at different levels inside an open mountain bowl.
Andorra / Canillo
Estanys de Juclar
Juclar rewards the transition from the welcoming Incles valley into a more mineral lake basin.
Andorra / Escaldes-Engordany
Madriu · Fontverd
