Nice climb up to Nippara. Lovely scenery and you can even see on old abandoned mine works rail track running above you. There is a 1km+ long tunnel on the way so ensure you have lights (there is a footpath too). On holidays the road can get quite busy and the road is narrow in areas so cars have to stop to allow passing. I hear the caves are great too but I wouldn't go in wearing sweaty cycle gear - it's quite cool in there!!
