Learn
Place-based education, taught where the place is.
Our programs explore the unique ecology of the Sierra foothills — through games, hikes, field study, and the kind of direct experience with real phenomena that turns kids into scientists and adults into naturalists.

Featured · Nature Camp
Riparian ecology, taught by the river it explains.
Each summer ARC explores the Coloma-Lotus valley with kids from kindergarten to high school. Campers learn riparian ecology through games, crafts, hikes, and music. Older kids raft the South Fork, sleep two nights under the oaks, and run a rope course. Members get $20 off any session. Scholarships are available — call us.
Registration for Nature Camp 2026 opens February 6. Camp Counselor applications close April 13.

Featured · School field trips
A field trip that holds up to the science teacher next door.
Each Field Trip is 2.5 hours, $10 per student with a $300 minimum, and runs rain or shine — a covered pavilion handles inclement weather. Curriculum is NGSS-aligned by grade band, from Patterns in Nature (K) to Wonderful Watersheds (3rd) to Spectacular Senses (4th). Students are using nature journals before they know what a nature journal is.
