Hi. Why the hell are you going to Jaca? :-) Must have a gig... Well, while you are in Catalonia (a nation invaded by the French and Spaniards 300 years ago):
Barcelona: go the La Sagrada Familia, El Parc Güell, Les Rambles. There is a service called "Bus Turístic", which leaves from La Plaça de Catalunya and does a good cricular tour for not much money. You can get hop off, walk around, explore, etc., then get back on later.
The rest of Catalonia: (look these up) Montserrat Besalú La Garrotxa Tossa de Mar (Costa Brava) La Seu d'Urgell Tarragona
That's a good start. I live in Sant Cugat del Vallès, near BCN.
-Heather P.S. We speak Catalan in Catalonia, and it is more important than Spanish here to most people; Spanish has been imposed for many years, but if you really wanna make an impression, just learn to say a couple of things in Catalan, and at least know what it IS before you get here. There are plenty of websites. Apa! Que vagi molt bé!! hhayes@inicia.es
