Sean,
Yes, Yelverton has expansive views onto Dartmoor. There is hardly a tree on the course and it can be very windswept. Gorse abounds! Thick, punitive stuff! There is an unusual obstacle in the series of Leats, drainage channels cut in the 18th century to gather water from the moors to feed down to the naval bases at Plymouth and Devonport. This was also a tin-mining place in the 19th century and Fowler's utilisation of the rubbish left behind was clever, providing him with any number of mounds and depressions around the greens. I have played it in mid-winter and the condition was excellent. There are a number of good short two-shotters.
If you are in the area, at the other end of Dartmoor, is Bovey Castle, formerly Manor House Hotel - an Abercromby layout. I am aware that there have been alterations since the place was taken over by Peter de Savary, including the construction of a new 1st hole. Its predecessor was bonkers! I imagine the place is now expensive. It was cheap in the past, not brilliantly maintained, but lots of fun. I hope the fun hasn't been taken from it.
Also if you happen to be down on the south coast of Devon, there are some magnificent views to be had from Thurlestone, high on the cliffs overlooking the sea. It's a Colt course with three very good par 3s in the first 6 and a hilarious opening hole of 268 yards on which you drive over a road and ditch with out-of-bounds left and right, deep seaside bunkers and a raised green angled across the line of approach. What makes it all so fearsome is that it is all too easy to misplonk the tee shot and clatter into the club house or car park. It's not a great course, but if you happen to be there you should not avoid it.
Saunton and RN Devon obviously are the biggest names in Devon but Bigbury, Churston and Ilfracombe are places I must revisit some day. Anyone know them?
