The best part of our trip to Barcelona was visiting Montserrat. The mountain is about an hour (by train) outside of the city, the train takes you to the foot of the mountain but included in your ticket is either a cable car ride or a funicular railway. We took the cable car to get the awesome views going up, and they really were awesome.
At the top of the mountain is a Monastery, there is also a hotel, canteen, and shop where you can buy cheese made by the monks, as well as a host of souvenirs and some terrible postcards.
It was quite hot and boyfriend dragged me on a walk up the mountain which was really tiring but enjoyable! We also had a little looksee in the religious bit and saw some nice candles before leaving to avoid the crowds of pilgramiging tourists and having to pay to go inside. We got lunch in the canteen, which had few signs in English, or signs at all as is the Spanish style, so I got a cheese sandwich and coke which was significantly impressive than our glorious surroundings.
