Key West City Cemetery, Key West, FL

Morbid as it might sound, you will enjoy wandering through this cemetery that happens to be a historic landmark. It was built in 1847 and covers nearly 20 acres. Here, you'll find the graves of sailors killed in the USS Maine in 1898, and many unique headstones, including one shaped like a ship's mast, and the famous one that reads: "I told you I was sick." Self-guided tours are free, and for a $10 donation in US Dollars, a 90-minute tour departs at 9:30 am on Tuesdays and Thursdays.
