My husband and I are planning a celebratory trip to Spain this summer. We have 3 or so days to travel from Barcelona to the Pyrenees and back to Barcelona for some moderate hiking, walking, possibly some biking - really taking in the beauty of the mountains, villages, countryside, etc. It's challenging to figure out our itinerary. Everything sounds so beautiful - I want to do it all, but we don't have a lot of time. Any suggestions of an intinerary, "must see"/"don't miss" places? There are national parks and some gorgeous sounding hikes. I"ve seen suggestions about Olot, Ripoll, Andorra. Any suggestions/ideas would be great! Thanks!
