Thawv txais ntawv is the Hmong term for letterbox. Welcome to this new series of London Letterbox caches honouring many different countries and languages around the world. This cache contains a stamp that is not a trade item and should remain with the cache.
From the listed coordinates, you will be hiking southwest into the field. You can find the final cache coordinates by projecting a waypoint 49 m away, at 238 degrees true.
