Going to Wales, know any good routes there?

Help, i'm staying in Corris for a week after the bank holiday. The missus hopefully won't notice when I chuck the bike in the boot on top of the wellies and raincoats. Does anyone do any riding in mid wales/snowdonia and have any GPX tracks i can punt in the Garmin? Ta.
