Turf Lock is that which marks the end of the Exeter Ship Canal. Thanks to its location on a popular foot and cycle path, as well as its excellent views across the estuary, it makes a lovely place to stop.
There's also a hotel/pub here, the Turf Hotel, which has a fantastic lawn between the river and the lock. With a cluster of pontoons and some little cruising yachts, the whole place is very picturesque.
