Ocean Boulevard (alternatively called 'O Street') is a street in Havana, Cuba that runs from the edge of Downtown Havana all the way through East Havana to the city limits at Rosslyn. The boulevard, which is almost seven and a half miles long, is known as a major tourist destination due to the prevalence of luxurious hotels at its western end, the world-famous Ocean Beach along much of its central span, and the pockets of nightlife, expensive apartments and shopping centers all along the road, culminating with extremely affluent beachfront neighborhoods at its eastern end before it diverts into the Cuba Coast Highway or turns inland at Rosslyn.
