I suggest you do not go near the streets between Old Dixie Highway and the Jupiter Ridge Natural Area alone at night.
This includes west of the natural areas and east of the highway but north of Admirals Cove Boulevard and Commodore Drive.
Those areas are high in miscellaneous and misdemeanor crimes, such as petty theft.
Violent Areas to Stay Away From
Compared to the majority of nearby metro cities, Jupiter is safe.
Still, you should take caution near Delta, an area northeast of the West Palm Beach Airport.
Delta seems to have a high violence rate.
I would check your crime reports and interactive maps out before you arrive.
Do not come here by yourself at night if you do not have a reason to.
