Can you take paddleboards in the spring? Is there a shuttle to get you back after your ride?

No paddle boards. Inflatables only. No shuttle either, but, it is not a far walk back. You can do as someone else suggested and go in at Kings Landing and paddle to Wekiwa Spring or Wekiva Island. These you would definitely want someone to pick you up at

You can probably take them but with the amount of people that are in the area, it would not make sense.

That question may be answered by the Park Ranger! I am not sure, but there are lots of people when the weather is warm!

I dont know rally, but inflatables yes.

Try kings landing

I don't think so

I'm sure you can take paddle boards, no there isn't any shuttle.
