The cache is located on one of the roads leading up to Valdemossa, one of the most charming cities on Mallorca Island.
The box is a blue plastic container. It holds a logbook, a pen and an air-pipe.
Valldemossa, just up from Palma de Mallorca is rather dominated by the Chopin and George Sand visit, especially as Sand wrote a rather uncomplementary book about that winter stay in Majorca. Seems the pigs worried her a little! Her book 'Winter in Majorca' is well worth a look.
Charterhouse, where Sand and Chopin stayed, is well worth a look. It does get crowded, and it can turn into a bit of a comedy act as you look round. You'll be quietly contemplating Chopin's cell, when suddenly either a Spanish, German or English band will cram into the cell for a talk by their guide. Note the tiles in Charterhouse, easily missed these on the floors as they're quite worn. There's some superb designs here.
