Summer on the beach

Summer, that time of the year when people have time to "relax", go to the pool, beach, hang out more ofter with their friends...

I like summer and go to the beach but, I'm that kind of person who loves get tone but hate being in the beach more than 2h. When I go to the beach I like to be near the water but sometimes it isn't a good idea because is where there are families with children, so probably you don't have rest.
