Bring your bikes and ride alongside the canal from bridge to bridge to bridge  (6.5 miles end to end; go as far as you like - just remember you have to get back to where you started).  Catch the fresh catch being loaded from fishing boats right into refrigerated trucks.  Buy some fresh fish directly at Fisherman's View, or try one of a few restaurants - see Eats below.

There's a Visitors Center which 55 has not yet visited.
