Although Warren Woods is quite small, just over 1/2 square mile, most of it is primeval forest. Although the immense beech trees are in a slow decline, there are still many that are close to 5 feet thick, and 100 feet high. There are areas where most of the ground is corded with tree roots. There are several paths through the woods, and a sturdy foot bridge over the Galien River. Bird life is abundant. There are a few picnic spots in a less densley wooded area.
