Places and how to pick up girls

You could say:

" heyy, my name is ---, would you want to walk with me for a little? "
" heyy, my name is ---, do you want to maybe do something later? "
" heyy, my name is ---, wanna hang out tonight or something?"

Things like that.. but maybe don't shake their hand if you know what I mean.. maybe just make it more casual and If they are with a friend.. then say something like hello ladies as a joke to make them laugh ;) Good Luck.. remember girls love when guys make them laugh.. so say stupid stuff or be like umm this is going to be retarded because I don't even know you but your really pretty so would you wanna hang out?

You should ask her if he would like to hang out with you sometime.

Ask them anything! Girls usually like to talk about themselves, so ask them any question, like why they come to the beach or what they do when they're not at the beach. Don't ask yes/no questions because it's too easy to just say those little words. If there's a vendor around, offer to buy her a snowcone or a lemonade or something. And above all, be confident!

Ask them if they want to hang out... if you are willing to talk to strangers you should be able to ask them anything.
