Hi ya. Been there many times. If you are facing the sea front at Sitges and head right for the gay nudist beach, which is for cruising, you will have a very long walk of a few miles and have to walk through a railway tunnel so I've been told! However, if you head in the left direction along the sea front, past the church towards the hotel at the end you will find a nice family gay friendly beach. Nude at the one end, but nobody seems to mind if you wander nude into the clothed bit!! I say family but most of the men there are gay. There is no cruising but I think its a really great beach. Hope this is of any help to you, have a great holiday.
