Well not quite, but something we talked about with regard to the Galaxie MTB Lift Pass
and looks quite interestings. Half the Pyrenees ski resorts now belong to groups and with a season pass you can ski in any member station.
i. Neiges Catalanes gives access to 8 resorts including, in France, Font-Romeu, Les Angles, Porté-Puymorens and Cerdagne-Puigmal.
ii. N’Py groups Gourette, Peyragudes, Pierre Saint-Martin, Domaine du Tourmalet - Pic du Midi, Luz-Ardiden and Piau-Engaly
iii Altiservice: Font-Romeu Pyrénées 2000, Saint-Lary, Artouste, Luchon-Superbagnères and Guzet.
Font Romeu seems to be in there twice, I guess it depends on whether you want to cross the border into Spain or not.
Season passes cost between 470 à 550€. It is an idea that we would like to see adopted by more second tier resorts.
