The local pub is within walking distance, it's down by the water. For groceries, Totnes is the nearest proper town, about three miles away. It's got a market and everything you'd need.
Dartmouth is about five miles. You can get boats from there. The coast isn't far, maybe a 20-minute drive to beaches like Blackpool Sands. The South West Coast Path is accessible from there if you want a long walk.
For National Trust places, Greenway (Agatha Christie's house) is nearby, just up the river. Dartmoor is about a 30-minute drive inland for a different kind of walk.
