I live in the NE of the Dartmoor National Park.
Exeter is 25 mins away. Plymouth a little more. Bristol a tad under 90 mins. Lot’s going on locally, and quite a few similar businesses, and we’ve just got fibre in the village. Direct access to the high moor in one direction and forests and river the other. Great MTB and road riding from the door. North Cornwall and South Devon coasts both within an hour. Loads of decent pubs in the area too!
I really wouldn’t live anywhere else.
350K would get you an average sized property of a good standard in the National Park itself but if you venture north of the A30 then you’d get something really quite substantial with views of the moor for that sort of money (5 bed detached place with views recently went near Winkleigh for under 300K).
