My 11 year and I did Turner River in December. Took us 4 1/2 hours. It was amazing. First half has several mangrove tunnels where you need to use arms to maneuver kayak. Directions easy to follow. Saw one person during whole trip. Saw several alligators, including one in front of us swimming towards us. Only downside was hard to find places to park to go to bathroom.
Put in on Tamiami Trail just past Turner River Road. Tight in some areas going thru tunnels in the mangroves. South to Hurdles Creek and East to spend the night on the platforms for camping. Kinda tight had company on the other half. Check tide charts for currents, kinda breezy in the winter but no bugs. 2 day trip out and back.
