We pass this spot many times going in and out of Colwall. Roadside parking is available throughout the village, which is also well-served by bus and train. There is no parking alongside the cache site, however.
Subterfuge and patience will be needed if cars are queueing at the nearby traffic lights.
Cache is easily reachable from pavement. You are looking for a black magnetic container: please bring your own pen/pencil. Tweezers may be required. Please tightly wrap log and replace in lid before screwing this into base.
