Dartmouth Harbour is a Trust Port in one of the finest natural harbours in the UK. The River Dart whose source is high on Dartmoor flows through the towns of Totnes and Dartmouth, South Devon, England. While the Dart is a busy port for local fishing vessels and naval shipping, it also makes an ideal and attractive stopover for smaller cruise ships and a wide variety of private luxury yachts. The river Dart is navigable from Dartmouth to the weir at Totnes.
