Fun Facts About Key Largo, Florida You Should Know Before Going

Key Largo is one of the most amazing places to visit for a sunny beach getaway in the US. There’s always a lot of history and useful information we should before heading to a place, just to not get there clueless and can’t find a lot about it online. That’s why I decided to list all the facts about Key Largo I could find and learn once I was there.

When researching our mini-honeymoon to the Florida Keys, I knew two things.

1. I wanted to do it on a motorcycle, and we did by renting an awesome Harley Davidson from Eaglerider to have the motorcycle road trip of our dreams.

2. To stay on a sailboat. I am not a sailor and have no interest in ever becoming one. But I DO have a huge interest to stay on a sailboat, which is a common rental option for the Florida Keys. We found the perfect one on Key Largo. And I, basically, got it out of my system.

The best part of staying on the sailboat was the evenings at the Marina. Nothing beats sitting on the quiet waters, overlooking the sunsets, and listening to lovely music playing nearby. This was the highlight of the sailboat stay, for sure!

One thing about Key Largo is that it’s completely different from Key West. We rented a bicycle to explore a bit and the trailer house communities, not all white trash but some of these trailers sell for over a mil a piece, have so much character that it was great to see how life moves forward on the largest Key.
