Mornings start early along the waterfront in Key West.

The predawn boarding call aboard the Yankee Freedom ferry is met with breakfast as we set our sights west to a cluster of Florida islands even farther west than Key West.

"Welcome aboard," snaps the public address system, as folks hunker down for the two-hour ride across turquoise blue waters. About 70 miles west of Key West awaits Garden Key in the Dry Tortugas, home to Fort Jefferson.

"It rivals Yosemite, Yellowstone and the big parks," Park Manager Glenn Simpson said.

Accessible only by boat or seaplane, this cluster of islands predates the Civil War.

Visitors arrive in this coral reef eco-system to explore a brick fortress, rough it at the campground and snorkel at this national park.

"My mom said, 'Let's go to the Fort. It's so cool! Blue Water!'" said Shannon Straub, who was visiting from Michigan. "So, we're here."

Construction began in 1845 in an attempt to protect cargo vessels sailing through the Straits of Florida.

"It's very protected for large ships," Simpson said, speaking about the cluster of islands.

By the Civil War, Fort Jefferson was a union prison. It was where Dr. Samuel Mudd, the man who conspired to assassinate President Abraham Lincoln, was imprisoned.

"It was a location that was isolated," Simpson said. "Pretty hard to get away from."

Recent restoration projects — and more to come — will shore up Fort Jefferson's future as a place to get a history lesson and peek under the surface.

"Under the water, filled with fish, coral, all types of sea life," snorkeler Andrea Sierra said.

A look under the surface shows a tropical reef system with corral and fish. Stray bricks from the fort also line the sandy bottom.

Yet all too soon, it's back aboard the Yankee Freedom for the long ride back to Key West. In all, visitors will get almost five hours on the island and lunch served back on board.
