From the carpark take the track at the listed waypoint to the cache.
This cache contains some additional copies of the detective notes you will need to solve the mystery. Please only take a copy if you have not brought a printed copy with you and only one copy per caching group - It would be great if they could be left in the final (Bonus) cache so I can recycle them again.
To solve the mystery and find out "who done it", you will need to collect the information contained in each cache secured to the lid of each container. By process of elimination of suspects, weapons and locations you will solve the mystery and with it discover the location of the final bonus cache.
Full details of the trail can be found on the listing for the Bonus cache. It is a walk of approximately 4 miles mostly on forest tracks and paths but most of the caches are hidden a few metres off the trails and will potentially require negotiation some steep or rough ground. Please take note of the attributes and terrain rating of individual caches.
The cache is placed in woodland managed by Natural Resources Wales (formerly Forestry Commission Wales) with their permission. See the agreement in the UK Geocaching Policies Wiki.
