Hey kids! Are you ready for a treasure hunt at the Arboretum? GeoKids is a fun-filled activity consisting of a brief classroom presentation on maps, directions and how to use a compass, geared for young participants. Kids then head out on a compass-based treasure hunt for prizes, with educational stops along the way. Ages 7 to 11 (adult presence required). Registration is required.
