Hey mate, sorry it took em so long to reply.
Sand jumps is in a diss used lead quarry east of Aberystwyth. ITs about a 20 minute drive from there. Go on the B4340 past trawscoed and the turning to llanafan, a few minutes after that turning, u turn tightly across a bridge then there is a 90 degree junction left. Take that and u should be on the road to pont-rhyd-y-groes. About half way along that road u should see the jumps down to the left which looks like sand. Hope this hlped cya
