Routes round Llandindrod

[Mark_h]

Hello. I'll be popping over your way next weekend. Will be based out of Llandindrod and looking for some good routes.

I know north to Newtown, then hanging a left to Aberystwyth is a good series of roads, but not sure where to go from there. Last time it was some tight twisties past some waterfall/valley/bridge affair whose name I can not remember.

So any "must do" roads round that area?

Thanks in advance,
Mark
