Rainbow River heads the list with a median of 509 cubic feet per second. The inn nights for this run are two, in Dunnellon in Marion County, and the car ride from the office to the headsprings takes about 2 hours over 97 miles.
On the water, the outfitter posts a single kayak launched at the headsprings for the whole day at $56 per boat, and the park charges $5 per vehicle to enter. The park asks visitors to hold a day-use slot at the headsprings entrance and shuts the gate once it is full.

Silver River comes second at a median of 491 cubic feet per second. Two inn nights sit in Ocala, also in Marion County, and reaching the river from Orlando means a drive of about 1 hour 45 minutes and 78 miles.
The outfitter leads a two-hour paddle in single kayaks, posted at $55 per boat, and park entry is $8 per vehicle. The launch closes 90 minutes before the park does.

Ichetucknee River ranks third, with a median of 260 cubic feet per second. Its plan runs three nights in Fort White in Columbia County, and the river lies at the longest drive on the list, about 2 hours 55 minutes and 148 miles.
A guide takes paddlers out in single kayaks for about two hours, priced by the outfitter at $55 per person, and the park charges $6 per vehicle. The north launch takes no more than 100 boats a day, and none go out after 3 p.m.

The Wekiva gauge near Sanford sits below the point where Rock Springs Run flows in, and it recorded a median of 214 cubic feet per second. Two nights are spent in Longwood in Seminole County, and the water is about 30 minutes and 17 miles from the office.
Day one puts each paddler in a single kayak on the Wekiva River for a full day at $47 per boat. Day two moves to Rock Springs Run for up to four hours at $54 per boat, and the landing adds $10 per adult; the landing allows no children under two on that run.

Weeki Wachee River is the last of the first-magnitude runs, at a median of 114 cubic feet per second. Its two nights are in Spring Hill in Hernando County, and the launch is about 1 hour 55 minutes and 80 miles away by road.
The outfitter sends a single kayak 2.8 miles one way and brings the paddler back to the launch afterward, at $35 per boat, while the park admits each adult for $13. The park caps launches at 70 an hour, and paddlers stay in the boat so the banks hold.

Chassahowitzka River is the one second-magnitude run, at a median of 53 cubic feet per second, measured as a tidally filtered figure because the river meets the Gulf tide. The three inn nights are at an inn in Citrus County, and the launch is about 2 hours 5 minutes and 87 miles from the office.
The outfitter guides a two-hour paddle in a clear kayak at $79 per adult. It starts from a campground canal, where parking at the launch costs $10 per vehicle.
