Forget checkered blankets and soggy PB&Js packed in plastic bags. Luxury is redefining the picnic. The stuff of Instagram and Pinterest dreams, luxury picnics are curated experiences, usually featuring gorgeous place settings, a low-sitting table, pillows, flower arrangements and soft, romantic lighting. Host one at a park, in a forest, by the beach or along the Hudson River with views of the city.

There are two luxury picnic companies based in North Jersey and several more in other parts of the state. Here’s what you need to know about each.
