The highest point of the GR11 is the Senda de Camille.

The Eriste Pass or Forqueta Pass (2,862 m) It is the highest point of the GR11. It is located on the variant GR11.2, between the Biados refuge and the Ángel Orús refuge or El Forcau.

In the main route, the highest altitude is reached next to the Pic Superior de la Vaca (2,820 m), in the eastern Pyrenees, between the Sanctuary of Núria and the Ulldeter refugeStage 38).

Furthermore, there are another 15 places where the GR11 runs above 2,500 metres, meaning 15 places where snow tends to linger into early summer.

Therefore, if you are thinking of undertaking the trek at the start of the season – May or June – it is worth keeping them very much in mind. Under normal conditions, many of these passes can retain snow patches well into June, and it is not uncommon for the use of an ice axe and crampons to be necessary.

Here they are, ordered from West to East, with their ranking position in parentheses:

• (5) Tebarray or Piedrafita Neck 2,782 m – Stage 14
• (12) Puerto Viejo de Brazato 2,566 m – Stage 15
• Chistau Pass or Estós Pass (2,572 m) Stage 20
• Eriste Pass or Forqueta Pass (2,862 m) – Stage 20v (GR11.2 variant)
• (3) Collada de Ixalenques (2,812 m) – Stage 22v (GR11.5 variant)
• (7) Pass between Estany de la Cap de la Vall and Estany Negre (2,715 m) – Stage 22v (GR11.5 variant)
•  (16) Collada de los Ibones (2,521 m) – Stage 22
• Caldes Pass (2,568m) – Stage 24 (GR11.18 variant)
• (14) Pòrt de Ràtera (2,534m) – Stage 25
• (6) Port de Baiau (2,757m) – Stage 31
• (9) Collet de Sant Vicenç (2,573 m) – GR11.10 Variant
• (13) Coll de Vallcivera (2,544m) – Stage 34
• (8) Portella de Calm Colomer or d’Engorgs (2,697m) – Stage 34
• Alongside the Pic de la Fossa del Gegant (2,800 m) – Stage 38
• Next to the Pic Superior de la Vaca (2,820 m) Stage 38
• (15) Coll de la Marrana (2,533 m) – Stage 38
• Roca Colom (2,506 m) GR11.6 Variation

However, while these are the 17 points that exceed 2,500 metres in altitude, they are not necessarily the only sections problematic with snow. Aspect, gradient or accumulation can make other locations even more treacherous. This is the case, for example, of the Añisclo Pass (2,485 m) or the GR11.4 variant itself through Ezkaurre, which, despite being close to 2,000 metres, can be quite tricky when there is snow due to the slope and north-facing aspect.
