Welcome to the Florida Key’s ONLY freshwater lake! The Blue Hole is a local tourist attraction that was born from a former quarry supplying the Florida Key’s with material for road beds in the 1930’s & 40’s along with stones for Henry Flagler’s East Coast Railway. The empty abandoned quarry over the years filled up with rainwater to appear as it does today supplying local wildlife vital freshwater.
Although I was expecting a brighter clearer blue shade of water, I can see how this has become a tourist attraction. If you look at the sign on the blue railing pictured on the left which reads: “Please Do Not Put Hands or Feet Through Railing”… I’ll finish what was left off: “Or You May Lose Them To A Hungry Gator!” Though others and I looked for gators, I’m sad to say we came up empty… but thank goodness, since there’s NO fence or railing stopping the gators from wandering onto the walkways only 6 or 7 feet away from the water’s edge! Don’t even think about going there at night or you might never return from which you came! 🙂 With that said, I saw only a turtle upon a rock and 3 mosquitoes (two of which bit me) 😦 on my journey to the Blue Hole, maybe your visit will produce a greater abundance of wildlife than I encountered! Happy hunting!
You can find this Blue Hole by driving down US-1 to Mile Marker 30.4 bayside and turning onto Key Deer Blvd. Once you’ve turned, simply go down 2.9 miles on your left where you’ll see the 8 car parking lot where you’ll pull in. Oh yeah, it’s against the law to feed the gators either willingly giving them food or being their food… the only difference is that if your their food… you won’t be prosecuted due to lack of remaining evidence!
