Grayling
EpicFreshwater
Lives in cold, clear streams and rivers, rising readily to dry flies and small spinners in bright daylight. Its sail-like dorsal fin and wary nature reward a careful approach and a well-presented drift.

Tips
- A well-drifted dry fly or small nymph is the classic, most effective approach.
- Approach quietly and keep a low profile — grayling spook easily in clear streams.
- Focus on cold, well-oxygenated stretches of river rather than warm, still water.
