We heard that there is a lovely walk between Espot & Boi. Apparently there are jeeps that get one into the park from Espot to Estany sant Maurici to reduce the distance of the walk, and likewise at the other end from Aiguestortes to Boi. We are thinking of doing this walk but have not been able to work out how to get back from Boi to Espot after the walk, assuming we are staying in Espot. If someone has done the walk this way I would very much appreciate if they can advise what to do. If not where am I able to obtain this information. From google map it is about 2 hours drive.
