Unfortunately, rural North Carolina is not pedestrian friendly and offers no public transportation. Cars, bikes, hover boards, etc. are necessary to get around. The street festival is being held in downtown Pink Hill which is most readily accessible by NC-11. Parking will be available both at the street festival location and around it.
If you are coming to the street festival from another city or state, you can take the Amtrak/Bus route into several cities, a bus directly into Kinston (the neighboring city), or an airplane into either Raleigh-Durham International Airport, Wilmington International Airport, or Albert J. Ellis Airport.
