The Little Red Schoolhouse is located on the northern (lake) side of Metairie Road between Beverly Garden Drive and Helios Ave.  The marker on this map provided by Google might appear slightly too far to the east -- the building is actually located between Dorrington Blvd. and Atherton Drive (not between Atherton and Jefferson). 

To access the front of the school from I-10, take the Bonnabel exit, travel south (away from the lake) until you reach Metairie Road, and then take a right and the school will be located on the right-hand side of the street.

Please note that the drop-off and pick-up spot for carpool is behind the school on Metairie Ave.
