How to fish it · for carp
When
Carp are highly active in warm water, feeding confidently on the surface and in the shallows. This is the golden window for fly fishing — visible fish, aggressive feeding, surface takes. Dawn and dusk are magic.
Where
Peak season for carp on the fly. Early mornings and evenings are best — carp cruise the margins, surface-feed, and tail in shallows. This is pure sight-fishing: walk, spot, stalk, cast. Keep low, tread softly, wear drab clothing. 5-6wt rod, 15ft fluorocarbon leader for sub-surface; floating line for surface. Have both a bread fly and a nymph rigged and ready.
The plan
Plan A

Peak season for carp on the fly. Early mornings and evenings are best — carp cruise the margins, surface-feed, and tail in shallows. This is pure sight-fishing: walk, spot, stalk, cast. Keep low, tread softly, wear drab clothing. 5-6wt rod, 15ft fluorocarbon leader for sub-surface; floating line for surface. Have both a bread fly and a nymph rigged and ready.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

About this water

Quirky urban carp-on-the-fly option in Madrid. The park lake is one of the city’s better-known urban carp venues, with fishing explicitly listed among the park’s permitted activities. Carp are the main draw, especially when warm weather brings fish into shallow margins. An accessible, low-barrier entry point for anyone curious about sight-fishing carp on fly — but always check current park and water-condition notices before travelling.
