If you want to see downtown Miami from a different angle this is your trip!
You can launch your kayak near Brickell Key and paddle upstream Miami River for almost 4 miles. The river is not as polluted as they say and the view of downtown and many cargo and river boats is great.
Be sure your stability control is good. You don't want to fall on this river since it has heavy traffic sometimes.
Restaurants on the way: GARCIA SEAFOOD...very good
No, river police approached me curious of seeing a kayak that far upstream but they were only that...curious
Take I-95 to calle ocho downtown Miami. park as close as Brickell Key as possible. launch from any of the edges facing Biscayne Bay
