Hello! you are more than welcome to snorkel. We are not on a canal, but directly on the Withlacoochee River. Now, we are an active marina, and Yankeetown is definitely a fishing village with lots of commercial crab and shrimp boats that travel the river daily. So you would need to be aware of any boat traffic that is on the river; but as far as us "allowing it", you are fine to snorkel if you wish!
Snorkel in the gulf a few miles out. Starfish, snappers and lots of sponges. Watch some YouTube videos they are very helpful.
