Miami's Riverview Park does get VERY crowded when the spoonbills are there (can be very entertaining!). You might also go upriver to Stepp's Ford Bridge (west of North Miami/Commerce). You can bank fish from there. Or, head out east of Miami 6-7 miles on highway 10 (Steve Owens blvd) to Spring River. You can bank fish along/under the bridge area. I believe there is a small camping area/boat ramp there.
