A reincarnation of a previous cache hide.
Marble Arch and Hyde Park are renowned throughout the globe. So here's yet another reason to pass by. The Royal Parks DO NOT allow caches within their boundaries.
So this traditional, but cache is hidden outside the park and is NOT on the perimeter fence. But close to it.
Due to possible problems over caching in this vicinity please avoid acting suspiciously whilst searching for the cache, and if challenged, explain about geocaching.
