What are some cute hairstyles when swimming?

I'm going to a gorge tomorrow with a couple of my friends but I don't know what to do with my hair. I want to pin my bangs down but I can't do a french braid. I'm thinking abut doing a twist braid and ending it behind my ears. My hair is long, brown, and has a couple of long layers. It's naturally wavy s I can do just about anything with it. Thank you so much!!!! :)
