As per previous advice, you will find some nice trout fishing on the Ericht, and the town water is as good a place to start as any. It's not, in many places, the easiest beat on the river to fish with a fly rod, unless you can roll/spey cast with the single hander, but in other spots you will find easy access to some good runs and pools. It is relatively inexpensive too. As per previous, speak to Kate Fleming, and have a wee look through her clearance stuff if you are looking for some new equipment.
