The link below is a good place to start. I visited the park in April of 1998. It is actually quite a beautiful setting. There are cannons that I believe are original, as well as the Schuyler house, (I think that is the name of it). People jog around its perimeter. There is a tour you can take while staying in your vehicle, stopping at the sequential signs that relate what portion of the battle took place at each site. The trees here and at the area near the battle of Lexington and Concord are very different from the ones I am used to seeing in San Jose, California, where there are plenty of oaks. The trees here seem to have somewhat gnarlier branches, heavier bark; they seem to grow out more horizontally as well; this is obvious because the climate back on the east coast is more severe than where I come from. There is a panorama of the battle as well as some slides with illustrations in the Park Center. Driving around the area was quite ethereal and dreamlike for me, it is located not too far away from a portion of the Hudson River. I think that it is better to go to the site in the summer months because they have special events such as re-enactments and music, and I am sure other interesting things. I don't know if this helps at all, this is my own angle. Walking on a battlefield, you sense a certain sacredness to the ground.
