Welcome to the board rellim. It should be called Boring river...well that's maybe a little harsh but as Jamaicarob said it's just "OK", IMO.
I bet the young guys would enjoy Mayfield Falls much more. The name is misleading, it's actually a guided walk upstream in a jungle river. Places to swim and dive along the way and neat cascades to sit under. Very beautiful. Bring water shoes. It's also a scenic mountain drive to reach the river.
