Geocache Description:

This second cache of the Caerphilly Collection involves walking on paths that are likely to be muddy. The nearest lanes do not lend themselves to parking and approaches from north or south necessitate 300' or more of ascent - but the effort will be rewarded with good scenery and fine views. This cache is close to the Rhymney Valley Ridgeway Footpath and is contained in a large plastic storage box.

The Caerphilly Collection is distinguished with a unique CC number and is made up of 50 caches. The caches vary in difficulty and type and usually have other "C" word connections - castle, cheese, coal, canal, etc. There may even be Cryptic Clues for Clever Clogs! The current Caerphilly unitary authority grew out of the former Rhymney Valley and Islwyn Councils and stretches from the outskirts of Cardiff and Newport in the south to the Brecon Beacons, north of Rhymney. Despite a past dominated by coal and heavy industry, it has a diverse history and varied and dramatic scenery. We hope you will enjoy exploring it with us.
Towards the end of the Collection is CC48 The Accumulator, the location of which is given in coded form. The translation details of the code are distributed around the whole Collection, but only about a third of the caches will contain a piece of the code, which is on the back of the Log Book. To do the Accumulator, you will need to keep a note of each piece of code that you find. Unless you are very lucky, you will need to find the majority of the Collection in order to do the Accumulator. The Accumulator cache is hidden in an area of difficult terrain and demanding navigation, with a 5, 4½ rating.
CC2 is also the second of a subset of the main series around the Rhymney Valley Ridgeway (RVR) Footpath. In this case, CC could stand for calcite crystals or calcium carbonate, of which they are a form. This section of the RVR Footpath follows a ridge of carboniferous limestone, the southern outcrop of a strata that is down-folded under the coal measures of the Valleys and re-appears along the southern edge of the Brecon Beacons. As at this quarry, the southern outcrop is often dolomitised (having a significant percentage of magnesium carbonate) and interspersed by mineral veins. At the quarry, you may find good examples of clear or opaque white calcite crystals with their characteristic rhomboidal (square pushed sideways) shape - but not to be confused with similarly coloured quartz crystals, which are harder and more complexly shaped and can also be found here. On a clear day, the ridge in this area offers views north to the main peaks of the Brecon Beacons or, south over Cardiff and across the Bristol Channel.
This cache may be linked with CC1, which is less than a mile away. The nearest lanes do not lend themselves to convenient parking - this is partly deliberate, as it is our hope that people will take the opportunity to incorporate the RVR Footpath into circular walks in the area. Possible starting points are Caerphilly Mountain, Rudry Common or Cefn Onn Park. If you choose one of these, be prepared for a 3-5 mile walk with a few hundred feet of ascent. However you approach, paths and tracks may be rough, wet or muddy in places, except during the most favourable weather conditions.
