A friend of mine insisted Mum and I go check out the Dry Tortugas while we were in Key West, and frankly, I wasn’t sure what to expect. An island 70 miles out at sea? A historic costal (unfinished) Civil War-era fort? The island itself is a national park, housing not only the fort but coral reefs that make for a great snorkeling spot. We took a two-hour long boat ride to the island and spent the day exploring; snorkeling; and sadly, getting sunburnt. It was worth it, though.
