Normally a 'hole' on Dartmoor refers to a narrow river valley or gorge and you will already find caches of mine at Tavy Hole, Broad Hole and Sandy Hole. However, Horse Hole is not associated with a similar feature but is just a depression in the ground close to the Summer Brook, a tributary of the West Dart.
IMPORTANT NOTE: This cache is located in the Merrivale Military Range where live firing occurs. You must check out the Firing Notices before entering the range. DO NOT ENTER THE RANGE WHEN THE RED FLAGS ARE FLYING. Never pick up any objects, they may be unexploded devices.
The weather on Dartmoor can change suddenly and unexpectedly and ALL types of weather conditions can be experienced. Please ensure that you have the correct clothing and map & compass (and know how to use them). Please do NOT rely solely on your GPS.
I would like to thank the Dartmoor National Park Authority for their kind permission to place this cache, which has been placed according to the new geocaching guidelines.
