Situated within 5 minutes from junction 48 of the M4 on a footpath that forms part of St. Illtyd's Way, this can be a quick cache and grab if you're just passing or if you've got about an hour to spend in the area, you could complete all three in the Trinity series.
As the name suggests, the Trinity caches are a set of three caches placed in the nearby area. Within this cache you'll find one half of a coordinate. Trinity suggests a three that is also one and in this case, you will need to complete this and Bont Trinity Micro (GC1A70C) to find the much larger container at Bont Trinity Part Three (GC1A70F).
Make a note of this coordinate (it's written twice on the paper strip for clarity) and combine it with the other half for a much bigger reward at Bont Trinity Part Three.
The difficulty rating represents not only how tricky it is to sometimes find a nano if you're not used to looking for something so small (though hopefully this one should be easy), it also represents the trickyness of actually getting to the location in the first place...
