How to fish it · for Brown Trout
When
Through the Castilla y León trout season. The Villagonzalo II beat fishes the lower Tormes — cooler than the Salamanca-end water but warmer than the Gredos headwaters.
Where
Villagonzalo II beat through the lower river. Pool tails, riffle heads, and the seams behind boulders.
Method
Upstream dry to risers; dry-dropper through the riffles. The Tormes runs clear granite water — long leader, fine tippet, careful approach.
Kit
9 ft #4 — Spanish granite spate default. Floating line, 12 ft leader to 4 lb fluoro. Studded boots — granite cobble runs slick.
Why this works
Excellent — water temperature is working for you, but time of day is the limiting factor today.

Directions
Seasons & zones
- Barbel 1 January → 31 December
Barbel is fishable year-round in Castilla y León's aguas libres, but a mandatory catch-and-release (zero-kill) window applies 1 May–15 July each year to protect spawning — anglers must release all barbel caught in that period (Orden MAV/1506/2025). This is a harvest rule, not a closure, so the season stays open throughout the year.
