As earlier stated, there are a number of bus routes from the Farmindale, NJ area that terminate at the Port Authority and Wall Street in NYC. There are also Park & Rides along the Garden State Parkway at most exits and the Monmouth Service area.
There is also train service on the North Jersey Coast Line, which joins the Northeast Corridor in Avenel, into NYC. The nearest station is likely Belmar, about 20 minutes away. You can transfer to PATH at Newark Penn Station or continue into NYC Penn Station on most trains.
