The Ocklawaha River was dammed up when the Cross-Florida Barge Canal was being built. You can only go as far as the Rodman Dam. Upon entering the river, we felt like little kids seeing Disney World for the first time. The scenery was breath taking and I can't adequately describe it. It was like being in Florida before it was settled. The Cypress trees, alligators, many species of birds, etc. were sights to behold. The only signs of civilization until the Rodman Dam were some pontoons and other shallow fishing craft. There is a landing just before the bridge at Rodman Dam, and this is a good time to break for a picnic lunch before returning to the St. Johns.
