Metro North is the easiest way to get to Beacon from New York. It departs from Grand Central every 30-60 minutes and you can buy tickets at the station or on via app (MTA eTix). Tickets range from $23-$35 roundtrip per person, and there are big discounts for kids. It seems intimidating but is super easy, feel free to reach out to us to help you with coordinating!
Flight
NYC has many airports but LaGuardia is definitely the easiest to get into the city via train, taxi, or Uber. JFK and EWR are also good options, but may take you a bit longer to get into the city!
