The Corvallis Environmental Center’s Avery House Nature Center focuses on early learning through nature-based education. We run the NaturePlay Preschool (for ages 3-5) M-F from 8:00 to 4:00 and our Exploradores de la Naturaleza (Bilingual NaturePlay Preschool) program (for ages 4-6) which runs T & Th from 1:00 to 4:00.
