A beautiful 197-acre estate characterized by forest, fields, ponds, streams and wetlands, Welkinweir is an educational center, providing an architectural, horticultural, historical, and environmental sanctuary.

    GVA’s Environmental Education programs strive to raise awareness of the natural world, as well as natural resource issues, by engaging participants in hands-on, nature awareness activities. Programs include stream monitoring, evening and weekend family nature programs, summer nature camp, and educational programs for schools, scouts and other youth and adult groups. Programs are offered at Welkinweir and at community centers.
