This cache is one of many that I have placed in Ciliau Aeron. It can be done as a stand alone or as part of a curicular. There is plenty of room to park near this cache.
Hidden up in these woods is a lovely little park for the geokids. Firstly you'll come across a castle-like wooden tower. Go further up and you'll find some things for the kids to balance along and to climb. There also some picnic tables up there. It's quite steep to get up to the park, but worth a visit.
You are looking for a 35mm container. Trees could be a problem for gps.
