The sea trout is a migratory brown trout. Like the salmon, it spends the winter months feeding at sea and runs into freshwater rivers in the summer months prior to spawning in the autumn. The best of the fly fishing in the British Isles is to be had during the hours of darkness throughout the summer months, particularly in June and July. This website aims to present a beginner’s guide to sea trout fishing, focussing primarily on night fly fishing on British rivers. Topics include articles and advice on where and when to fish, fly fishing tactics, tackle and flies, with a section devoted to fly tying and pages showing maps and information on the main British sea trout rivers.
