Can anyone point me in the direction of some gentle, non-damaging lanes in N/Wales?

I am taking my Disco into the Snowdon area for a week, next week, and would like to take in a couple of drives whilst we are there. They need to be fairly gentle lanes as the Disco has an LPG conversion, of which the undersill tanks mean marginally reduced ground clearance (think side-steps). In terms of driving ability though, anythings on!!! Just need to be careful with the car...

Just bumping the thread.....

If anyone does have any ideas, I'd love to hear them too... North Wales is my nearest potential plaground too, and I would love to hear about any potential tracks of a similar diff level....

The 'wayfarer' route has been mentioned to me (google it if you're not sure) but would love to hear any experiences or advice?

Thanks in advance!
