North Shore Kayak

The mid-point of the river from a standpoint of "which way does the tide flow?" seems to be between the railroad bridge and the 128 bridge, so if you are going clockwise, you want to be there at exactly high-tide.  The worst thing to do would be going on the north stretch of the river against the tide – this is painfully slow. 

People in the know say that the direction (clockwise or counter) is not as big an issue as the tide.  The route shown below goes counterclockwise, leaving from Rockport Harbor.

Good luck - bring plenty of fluids!
