Sandspur Island (Raccoon Island): Miami's Wildlife & Island Paradise
Discover the official story, ecosystem, and wildlife etiquette of Sandspur Island — Biscayne Bay's famous uninhabited sanctuary inhabited by friendly island raccoons.
History & Geographic Facts: How Sandspur Island Was Formed
From an artificial Army Corps spoil mound to a lush maritime hammock ecosystem in Biscayne Bay.
Dredging Creation & Man-Made Origins
Sandspur Island originated as an artificial spoil mound created during 20th-century navigation dredging projects by the U.S. Army Corps of Engineers. Millions of cubic yards of dredged sand, limestone, and sea shells were deposited until emerging above sea level. Over decades, natural mangrove seed dispersal and ecological restoration by Miami-Dade DERM transformed the barren mound into a 15-acre tropical maritime hammock.
Official Geographic Name vs. Nicknames
On official NOAA nautical charts and federal surveys, the island is designated as Sandspur Island. However, local boaters, commercial captains, and international travelers universally refer to it as Raccoon Island due to its habituated wild wildlife population. Historically, it was also colloquially nicknamed "Beer Can Island" by mid-century boaters before environmental cleanup programs were instituted.

The Island Raccoons: Wildlife Facts, Health & Safety
Learn how the raccoon colony established itself on the island, their health monitoring, and safe viewing tips.
Understanding Miami's Island Raccoon Population
The resident raccoon community on Sandspur Island consists of roughly 40 to 60 diurnal raccoons. Unlike mainland urban raccoons that forage strictly at night, the island raccoons are active during daylight hours, frequently wading into shallow tidal waters along the beach to greet arriving paddlecraft and boats.
Local environmental authorities and wildlife biologists conduct regular Oral Rabies Vaccination (ORV) bait drops across Biscayne Bay spoil islands. Wildlife monitoring confirms the population is healthy and rabies-free.
Raccoons are proficient natural swimmers. Decades ago, founder raccoons swam across narrow channels from mainland mangrove forests during low tides or rafted across during major storms.
