How to fish it · for Brown Trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.

Arundell Arms water — Tamar & tributariesAccess varies
The Arundell at Lifton holds many miles of private fishing across the Tamar and its tributaries (Lyd, Thrushel, Wolf, Ottery, Lew), the classic hotel-water base for the system.
Visit official site ↗Endsleigh water — Hotel Endsleigh / Endsleigh Fishing ClubAccess varies
Hotel Endsleigh, through the historic Endsleigh Fishing Club, offers guests around eight miles of bank on the Tamar for fly-fishing salmon and sea trout — among the better-known salmon water in England, though the run is now autumn-weighted and conservation-sensitive.
Visit official site ↗Westcountry Angling Passport beatsAccess varies
Sections of the Tamar system are open through the Westcountry Angling Passport (via the FishPass app) — the simplest no-booking visitor route.

Directions
Seasons & zones
- Salmon 1 March → 14 October
- Trout 15 March → 30 September
Sea trout: Variable seasonal (2026)
Salmon: Negligible (2026) — EA 2024 Salmon Stocks Assessment classifies the Tamar 'at risk' — egg deposition below Conservation Limit, mandatory C&R. The Gunnislake fish counter has charted a long-term decline since the 1980s. The river still produces salmon every season, with autumn runs more reliable than spring fish; the sea trout (peal) run is the more dependable draw on the middle and lower beats.
