'To return to my trees' is a Welsh idiom describing a 'balanced state of mind'.
To find this cache you must 'return to our trees' by completing the 'Dod yn ôl at fy Nghoed' Adventure Lab. LINK
Each completed Lab will provide you with two numbers, take these as:
Derwen Meurig = A B
Yw Llanddeiniolen = C D
Masarnwydden Nant Peris = E F
Ffawydden Plas Newydd = G H (Access Fee)
Derwen Lucombe Paxton = J K
The cache is hidden somewhere in Parc y Dre, Caernarfon. A very apt location for a cache about trees, and you'll surely notice why!
You'll find the cache at N53 0(C+H).(J+A)G(E-J) W004 1(B-F).K(D/A)(F+J)
