The harbour at Salcombe in the South Hams (South-West Devon) is not on a river but an inlet, as the water-taxi driver told me when I took a walk onto the floating pontoons where people waited to be picked up by water transport. That was the day we went to Burgh Island, and, coming back, we called in at Salcombe for an ice-cream and a stroll around the harbour.
As you can see from the photographs, Salcombe is a well-loved spot for tourists, especially those who enjoy sailing and yachting (and the more sedate folk who simply like to sit on a bench by the waterfront and watch the life on the water).
