Drumradoch Estate - River Belvaig

The Upper River Balvaig is a striking and underrated fishery in the Balquhidder glen, offering intimate fly water in one of the most scenic parts of the Trossachs. The river flows out of Loch Voil and winds through a landscape rich in history and wildlife, including water overlooked by Rob Roy's grave. This is primarily a salmon river, but it also offers excellent brown trout fishing and the chance of sea trout later in the season. For anglers prepared to walk, learn the access and fish a little differently, it is one of the most rewarding smaller rivers in the Teith system.

The Upper Balvaig is best known for salmon, especially spring fish that may appear as early as February or March when water levels are right. Brown trout are an important part of the fishing and can provide excellent sport throughout the season, while sea trout are fewer but possible. The upper tree-lined pools and runs are classic salmon water and suit short-line fly presentation, while the slower downstream farmland sections can offer trout and occasional sea trout. This is a river where anglers should come prepared to target all three species, adapting method and fly choice to water height, season and pace.

This is a lightly managed river in a working rural landscape, so careful access and respectful behaviour are essential. Anglers are expected to use gates properly, respect livestock, keep to riverbanks and fence lines where advised, and fish with sensible catch-and-release practice. Nets are encouraged for all species, including salmon, and anglers should move carefully on gravel bars and higher banks. The fishery's value lies partly in its natural state, so good rivercraft, gentle access and responsible behaviour help preserve both the fishing and the special character of the Balvaig valley.

The Balvaig rewards a planned approach. Access can be awkward at first for new anglers, with layby parking, some fence crossing, rough ground and high grass in places. The river is usually clear because it is fed mainly from Loch Voil, so water levels and timing matter more than colour. Around 2ft on the bridge after a flood, as the river drops, is considered especially good for salmon. Bring a wading stick, rubber-soled boots and a floating line with sink tips. A morning on the upper pools for salmon followed by trout fishing downstream later in the day can make an excellent plan.
