Once a thriving settlement along the St. Lucie River, the community of Spruce Bluff vanished long before this 97-acre patch of green was hemmed in by subdivisions. The interpretive trails at Spruce Bluff Natural Area lead you back in time not just to the 1890s settlement site, but to the largest mound known to left behind by the long-forgotten Ais, a 20-foot-tall, 180-foot diameter structure on an island in the marshes.

From the trailhead, the Pioneer Trail heads north along an abandoned entryway to a thwarted development through scrubby flatwoods and scrub, terminating in a loop around a pioneer-era cemetery circa 1891.
