I had a great time kayaking in Key Largo! There are many kayaking spots where you can rent kayaks and paddle boards. It cost us around 50$ per kayak for the afternoon and we were able to park them and swim in the mangroves! I loved this experience but I did do it with someone who was very knowledgeable about the area and the sea. I would suggest knowing about the Key largo waters before adventuring into the sea. We did sea a barracuda and some nurse sharks so being aware of your surroundings is crucial! Would definitely do it again !
