The American River Natural History Association (ARNHA), an education non-profit, operates the Effie Yeaw Nature Center within Ancil Hoffman Park in Carmichael.
The Nature Center is open Tuesday - Sunday features native animals, a nature gift shop, and a museum.
The Nature Center includes a 100 acre natural area with access to the Lower American River where visitors can get close to deer and turkey plus have access to one of the most protected oak woodlands of this region.
There are several easy walking trails available to visitors. The Nature Center offers a variety of year round natural science and cultural history programs to the general public, adults and primary school classes.
ARNHA is a membership organization which also publishes books and information about the Lower American River region. People interested in ARNHA can call 489-4918 or visit the Nature Center during business hours (except Mondays).
Admission to the Nature Center is free but vehicles coming into Ancil Hoffman Park must pay a parking fee (usually $5) or have a Sacramento County Parks Annual Pass.
