U.S. National Park Series (2) - Dry Tortugas National Park

Dry Tortugas National Park is the tiniest national park that I have been to. It is also one of the remote national parks that I have been to. (The other one that I have been to and would consider remote is the Katmai national park in Alaska.) 

Located about 70 miles west of Key West, this national park is composed of some small islands. People usually go to the biggest one - Gardden Key - which has only 100-square miles and is accessible only by boat or by seaplane. The park is the home of Fort Jefferson, which is a unfinished coastal fort. I went there in 2008 when I was still in my graduate school in Florida.
