Frongoch is the Aberystwyth AA's headline water — eight hectares roadside above Pont-rhyd-y-groes, fly-only, four boats, and a stocking policy that puts decent rainbows over a steady head of wild browns. Caravan-holders get priority Monday, Tuesday, Thursday and Friday, which is worth knowing if you're planning ahead. The fishing is honest and the access is straightforward — it does what a small Welsh stillwater should do.
