The main beaches in Benidorm are Levante and Poniente.
Levante has more bars, cafes, shops and clubs - it is where most of the action is - especially at night.
Poniente is by no means quiet - but it has less going on, especially at night than Levante.
There is also a small beach below The old Town - and a nice little beach - La Cala - at the western end of Poniente.
For gay men, the main attraction is Raco de Conill at the western end of La Cala.
