The Yale Nature Preserve is just off of Fountain Street in New Haven, between the bustling Merritt Parkway and the sprawling expanse of the Yale Golf Course. The is no parking lot, only street parking, and there are no signs for the preserve. This hidden gem has an extensive network of trails through the forest and at its southwestern end there is the infamous "foam house" ruins which are whats left of an abandoned experimental housing project from the 1960s.
