Trying to plan a hike in Brecon Beacons, camping over one night on route. Wondered if anyone has any advice on how you would/could get to start from finish points? Train looks like a no go, park and taxi or is there any transport companies etc.?

Any help appreciated 

Depending on where you are planning on starting. The T4 bus runs from Cardiff to Brecon and stops at Story Arms which is basically in the middle of the beacons

Head a bit further east and you could do a circular route from Crickhowell.  Could stop over in the bothy near Waun Fach. Plenty to go at around there.
