The Coxheath and Back walk is approx 9KM and has 31 caches. There is other caches in the area/almost en-route. You have to walk down a big hill and there is a slight incline at the end of the walk. The walk is mostly on foot paths and a small amount of road walking on quite lanes. You cross one relatively busy road twice. Please take care. There are two styles and can get muddy in places. Tweezers are recommended on this series.
