I 
Geocaching and I a bit of geoart! I also think geocaching by bike can be a fun way to cache which got me thinking.......
So here we go.... a mix of caches along the cycle routes between Pontyclun to Pontypridd. Some 'Swiftie' puzzles in the middle purely to make the simple geoart. All intended to be easy finds so you can just hop off the bike (no need to go too far off the path) and hop straight back on the bike with a smile or at least a smiley 
!! There's also plenty of parking along the way if you dont fancy the whole P2P and back (30km) in one trip
