The west bank of the St. Johns river meets Orange Park just South of I295. It also feeds the inlet of Doctors Lake. The name Doctors lake can be a bit deceiving it actually is just a very large inlet (13 square miles) and it's water is brackish.
The South end of Orange Park meets Doctors Lake while the North End of Fleming Island meets the south end of Doctors Lake. To the west is an area of Jacksonville called lakeside.
Orange Park doesn't provide any creek front homes but the riverfront on Doctors Lake is considerably less expensive than St. Johns riverfront living.
