To flock to something describes the movement of large groups of people towards a destination.

Examples:

Thousands of people flocked to the shopping centre when the mega-sale started.

Youngsters flock to cinemas to watch the latest blockbuster action movies.

Take note:

Birds of a feather flock together is an expression which means that people who are similar or have similar interests tend to be close or support each other.

Example:

Dictatorial presidents tend not to criticise each other’s regimes. Birds of a feather flock together.
