If you come to Barcelona this place is a must, be it day or night. In the morning you can sit in the terraces protected in the long shadows of the arcade or under the palm trees. At night trendy bars or night clubs await. You have hostels and restaurants, you have concerts, you have small thieves and police cars. You name it.
During my many incursions in Las Ramblas I like to hide from the sun and steal some back light pictures like these.
