Audubon Greenwich — Establishment and park at 613 Riversville Road, Greenwich, Connecticut.

This is an excellent place to take groups to visit and tour. I went to this place as part of a school sponsored trip for elementary students. The staff and volunteers did a superb job of engaging the students and the students loved the hiking and exploration (both indoor and outdoor) activities that were planned for them. I strongly encourage anyone who is looking for an outdoor nature exploration experience for a group of kids to include this place as one of the sites they visit.
