Was just there tonight and looked at two different ramps. Only one looks like it can be used by non airboats.
Ramp with water:
I75 exit 368
East on 318
North on Hwy 441
East on NW 191 St Pl (BP gas staition on NE corner)
Heagy Burry Park at end of road
Weeded up canal
CR 325 just south of Cross Creek in park
