St. John's River is unique among rivers, and not just Florida rivers. It's one of the very few major rivers to flow north in the world. And at three hundred miles long and often two miles across, St. John's River is certainly a major river.

It's also a very houseboat-friendly river. Since the elevation change is negligible (there's only a 30-foot difference between the river's highest and lowest point), the St. John's River flows very, very slow, and very, very wide. You'll have plenty to see while cruising at these extremely leisurely paces. The river winds through rich green basins, partly preserved through the state parks system, that birds flock to by the hundreds and thousands.
