Explore Rambla de Canaletes
This famous street is lined with larger stores, but the middle is filled with the perfect souvenir shopping experience. From colorful scarves to sweets to the ever important shot glasses, this is one fun attraction.
Pro tip: Right off of this street is La Boqueria Market, which is a must-do all its own. There's locally-made meats, fruits, and cheeses and you'll only spend a couple euros.
