Had a wonderful experience renting two kayaks from Kayack Jacks. I called and confirmed the time a few days before and upon arriving the kayaks were ready at the launch point. We received waterproof maps, paddles, and life jackets. Did not see any manatees, but did see many mullets jumping out of the water. It's easy to get turned around without the map so it was great to have it and they even offered me a dry bag to borrow as well to keep my phone in. We turned around at about 45 minutes in since we had other plans that day, so it took us about 90 minutes total, but the rental is up to 4 hours. We've been kayaking before so we opted for self guided. If this is your first time kayaking, I recommend going on a guided tour and whether you have a guide or not, bring lots of ice water to drink, snacks, sunscreen and a big hat. You will likely get tired and hot from all the paddling. Wonderful experience! Gorgeous scenery. Can't wait to get out on the water again!!
