ABBA Gold is a series of nineteen puzzles, plus a bonus, inspired by the song titles on ABBA's best-selling album, "Gold: Greatest Hits". The caches form a circuit of roughly five miles, on some pleasant footpaths around Pirbright. Be prepared for wet and muddy conditions!
See ABBA Gold (the bonus puzzle cache) for an overview of the series.
