Jean Williams, who runs Sweets Fishing Tackle, is something of a legend in the world of fly-fishing. She provides, as well as the permits, an information service about the state of the river, a warm welcome for visiting fishermen and regulars, and enthusiastic appreciation of any fish caught. Jean can also tell you about about the private salmon fishing beats in the area and put you in touch with owners.

Her shop in Porthycarne Street is an Aladdin’s cave of fishing flies, boxes of feathers and other fly-tying paraphernalia, rods, reels and landing nets, as well as photos of many past fishing triumphs.
