Dartmoor National Park is clearly renowned for its upland moors, but a large part of the National Park is lowland heath and farmland, particularly in the east.
The lowest place of all in the Park is Doghole Bridge in the lower Teign valley, and the cache is hidden nearby.
This is a cache and dash. There is space for one car right at GZ, but please don't block the lane which is in constant use. GPS reception is poor so the clue is detailed.
This cache is part of the Heart of Dartmoor Series. The original cache is long lost, but for reference, B=5. This may help you find the Heart of Dartmoor Bonus
