It is only about 1,140 acres (460 hectares) [2] in comparison to its larger neighbor, Big Pine Key, which lies about half a mile (800 m) to its west.

It is accessible by a concrete bridge from Big Pine Key and was the terminus of a car ferry that existed before the present Overseas Highway was built on the remains of Flagler's Overseas Railroad.

[3] No Name Key was known for not being connected to the commercial power grid, for a local county ordinance prohibited this.

Residents mostly used a combination of solar energy and diesel or gas generators.

[4] This prohibition of commercial electricity sparked a lawsuit between Monroe County and the No Name Key property owners.
