Bargoed Park is the unlikely one — a restored post-industrial park fishery in the Taff Bargoed Valley just outside Trelewis, on Coal Measures geology that's wholly different from every other water in this batch. Two lakes, four-acre top and one-acre bottom, stocked with brown and rainbow trout, with platforms, disabled pegs and a snack bar. Year-round access. Fly and worm permitted. The opposite of the high Carneddau llyns but exactly what some days call for.
