Buckingham Palace, it is a place you cannot miss if you go to London, and if is possible you should see the Changing Guard. After you can walk from Buckingham Palace to St. James Park, it is very nice to see.
Sant Martí d´Empuries, near to L´Escala in Costa Brava, small village with a romanic church, very quiet during the winter, and crowded at summer. Also the typical “MASIA” catalan house it is like a farm.
From time to time I go to Andorra , if I have time I normally try to go to Aix les Thermes, the distance from Andorra la Vella it is about 60 kms, it depends on the season Andorra is crowded because of the Ski. In the way of curves you can see the snowy mountains, once you reach Ax-les-Thermes in France you can see a town, with a beautiful church. Ax-les-Thermes is well known because of the thermal waters, so if you like you can sit in the “Cuenca of the Ladres” and have a relaxing foot bath.
