Although named Big Tree Loop, only a small section of this trail is a loop, the rest heads south and only forms a loop if combined with other trails.
The loop section of Big Tree Loop connects Spook Rock Trail
with Peggy's Way Trail
, and (via a very short connector) the Old Croton Aqueduct Trail. Old Croton Aqueduct Trail is in a different park.
The "handle" of the "lollipop" trail heads south and connects to the Pocantico River Trail
before ending at Peggy's Way Trail
and another connection to the Old Croton Aqueduct Trail.
