To see something of the countryside outside of New York and to see some Fall colour we caught the train to Kykuit. We travelled alongside the Hudson, sit on the left side of the train, then we walked through Tarrytown and Sleepy Hollow to the meeting point for the tour guide and bus. We took the Classic tour, which gave us lots of information, and i would say that for the casual visitor this is more than adequate.
The house and contents were worth a visit and we had an enjoyable day. Doris, the guide, was good too.
