I put mine next to the cliffs. I'd say either the top left stretch like TheGreatBrain said or on the landmass your house is on
Whatever you do, don't rush it. Take your time. I played for about a year before I finally settled on a spot.
I think the upper left corner next to the train tracks looks like a nice spot. Some people like placing cedar trees around their campsite. If you put the camp too close to the beach, they will die. This way, you can have cedars around it. ( If you want them ).
