Spain: Sea Trout and Atlantic Salmon in Northern Spain



Over the years, we’ve come to the conclusion that Spanish fish take a perverse pleasure in producing the unexpected, and so it is we are able to offer you sea trout on the dry fly in the midday sun and the southernmost population of Atlantic salmon.
Sea Trout

If you’re prepared to throw out the rulebook and every preconception you have about sea trout fishing, and in return have the opportunity to bask in Spanish sun and hospitality while you flick fluff (yes, fluff, not nymphs), Asturian sea trout are for you.

Spanish sea trout have cultivated adaptations that defy the natural order (at least as we fishermen perceive it). That means turning the tables to become day-feeding, surface-rising silver fish with a suspicious, sceptical bent that makes them a challenge to catch. Even when you can see where you’re going without the British sea trout fisherman’s requisite night vision gear.

Crystal clear water and sunlight makes it easy to see pods of sea trout as they migrate upstream, feeding as they go. But as ever there’s a trade off: they can see you, too. These migratory trout rise to mayfly, ants, caddis, midges and more, just like their non-migratory cousins the brown trout.

The fishing is challenging: leaders in excess of 20 feet, thin tippet and tiny flies require technique to present naturally.

Fortunately, our local guide is an expert and innovator who is only to happy to teach the intricacies of presentation.

Atlantic Salmon

At the southern extreme of their range, Atlantic salmon are thriving in crystal clear cool waters of Asturian rivers where more consistent water flows have meant a plentiful historical run.

Fished for using nymphs and swung traditional flies and double handed rods as one would in Scotland, these silver visitors offer the opportunity to hone ones skills or hook a big fish while getting a tan.






The rivers we fish are managed with a complex system of open pools and ticketed waters that is peculiarly Spanish. In a big to encourage fly fishing tourism, the Spanish have extended special privileges to foreign fishermen pursuing sea trout and salmon.

To get access to the best pools, you need to book by January when the fishing lottery takes place. We can guarantee good fishing, fabulous scenery and gourmet regional food, but the specific pools are down to the luck of the draw in the lottery.

Most of this salmon and Sea trout fishing involves wading. We strongly recommend that you use a wading belt and wading stick when wading. On rivers which present difficult wading, or where the flow makes wading challenging, we also recommend wearing a life jacket for your safety and peace of mind.
Polarised sunglasses and a hat will not only provide protection, but make spotting of fish easier.

It is standard practice to tip the fishing guide at the end of the day or trip. The size of tip varies depending on the river (the more famous the river the bigger the tip expected), the number of days fishing, the number and size of fish caught, the amount of coaching and assistance requested of the ghillie, whether you are the host or the guest, and how much fun you’ve had.
Of course tipping and the amount tipped are at your discretion, but there are a couple of different ways to work this out. One school of thought is to tip between 10 and 20% of what you are paying for your fishing. Others calculate it on a flat rate per day (usually somewhere between £30 and £100), still others on a lower flat rate and then an additional £10 a fish for each one caught.
