(S) From Pas de la Case, head due south towards Estany de les Abelletes, following the border as closely as possible. To do this, follow Avenue d’Encamp; at the first junction, turn left (both roads have the same name), then, at the second junction, turn right and continue to Estany de les Abelletes.
(1) Go round it on the right, following the well-marked path which climbs gradually, still within the ski area, and heads towards the Coll dels Isards.
(2) Continue along the path towards a second pass, also called Coll dels Isards, which is clearly visible. You’ll reach it after climbing about 100 metres in altitude, having passed through a sort of hollow between the two passes.
(3) Leave Andorra and cross into France. Continue along the same path and enter the Camperardos Valley alongside the Estany Negre or Estany de les Passaderes.
(4) Walk along the eastern side of this small lake, then head slightly lower down (south-south-west) towards the Portella Blanca d’Andorra, which is effectively a sort of undulating white pass that is very clearly visible and extremely easy to cross.
(5) There, join the GR®107, which heads first westwards and then south-westwards on a gentle descent. You’ll first cross back into Andorra and then quickly enter Spain (Catalonia). Continue on a pleasant descent through the Vall d’Engaït until you reach a junction with the GR®11, near the Cabana dels Esparvers.
(6) Leave theGR®107and follow the GR®11 to the left, heading due east towards the Portella d’Engorgs, situated 600 metres above. The path is very well signposted, but the climb is steep.
(7) Begin the descent, which is a little tricky at first over scree but becomes easier once you’ve cleared the first steep section. Continue, passing along the edge of the Estany dels Minyons and the Estany dels Aparellats. You will then reach the Joaquim Folch i Girona Refuge (E).
