The activity of Letterboxing originated on Dartmoor – it was started in 1854 when James Perrott of Chagford set up a small cairn at Cranmere Pool on north Dartmoor. Inside he put a glass jar where visitors who had ventured to the lonely, bleak spot could leave their visiting cards.
From this hikers on the moors began to leave a letter or postcard inside a box along the trail, hence the name "letterboxing". The next person to discover the site would collect the postcards and post them.
Letterboxing combines orienteering with treasure hunting and puzzle solving and is a great way to introduce children and young people to the joys of exploring Dartmoor and improve navigation skills.Here’s how you can find out more
