Trivia: What was the first national park east of the Mississippi River?
Acadia
Shenandoah
Voyageurs
Isle Royale
The correct answer is Acadia
So why is this answer correct? : While Yellowstone may hold the title as the first national park in the United States, Maine’s Acadia National Park was the first national park established east of the Mississippi River in 1916. And it’s been a hit ever since: Today, Acadia is the second-most visited national park east of the Mississippi.
