Virtually every visitor to Tijuana has to experience at least a brief stroll along raucous Av Revolución, also known as 'La Revo'. It's a mishmash of nightclubs, bellowing hawkers outside seedy strip bars, brash taxi drivers, tacky souvenir stores, street photographers with zebra-striped burros, discount liquor stores and restaurants.
If you're walking north to south but find the sensory assault from high-tech sound systems too overwhelming to return the same way, try the more conventional shopping street of Av Constitución, paralleling La Revo one block west. It has a far more local flare.
