There are lots depends what you want- strenuous or easy. The tourist centre in Crickhowell has detailed leaflets for about 50p . Table top mountain is good . A few hours and lovely views over the valley
I'm doing the holiday ticket and I'm looking into a few walks too.
Am I right in thinking that one can walk from Glanusk park to Llandgnidr via a canal? It's a bit difficult to tell from the map I've got. Also does anyone no what sort of shops are in Llandnidr, as I'm goning to need some food stuffs.
