There is no subway. You can take the train to Jamaica and then a bus or Uber. There are buses daily from crown heights right outside the Kingston avenue stop of the 3 train. The bus goes daily at 10.30am and costs around $10 for a two way trip. There are also other buses from crown heights and from boro park and Williamsburg. Google ohel bus to see full schedules.
