The Dartmoor Loop is a great Ride Out route for bikers who like plenty of variation in their scenery. It starts and ends in the large village of Yelverton, on the edge of the Dartmoor National Park, and basically does a large figure of eight through and above the moor from there.
From Yelverton the route cuts across Dartmoor to Moretonhampstead, via the B3212. Be careful of livestock and also be aware of the 40mph speed limit. On a clear, bright Autumn or Winter day, the views are stunning and there are plenty of stop off points if you want to stretch your legs.
At Moretonhampstead, you can do a slight detour, via the A382, and head over to Trago2Wheels just off the A38, for a cuppa and a bacon sarnie. Then head back up to the northern tip of Dartmoor near Okehampton before riding down the A386 towards the ancient market town of Tavistock.
From Tavistock, take the B3357 towards Two Bridges/Princetown, where you can pick up the B3212 (via the small Stone Age standing stone avenue and hut circles at Merrivale) back to Yelverton. The Dartmoor Inn at Merrivale and The Rock Inn at Yelverton both serve delicious lunches and there's hard standing for bikes.
