Sangro (Alto Sangro)
The Sangro starts high under Monte Turchio inside the Parco Nazionale d'Abruzzo, Lazio e Molise, drops through narrow gorges past Villetta Barrea and the Barrea reservoir, and by the time it reaches Castel di Sangro it has built a reputation that draws fly anglers from well outside Italy — wild brown trout that regularly push two kilograms, big by any Apennine standard.

How to fish it · for Brown Trout
When
Spring through to the late-September close, with the biggest fish most catchable in the low, clear water of early summer and again as the water cools in September. These are wild, wary trout in gin-clear water — overcast light and a lift in the river both help your chances.
Where
The reach between Castel di Sangro and the Ponte della Maddalena is the known water, and it earns its reputation — deep pools and long glides that hold serious fish. Above Villetta Barrea and the Barrea reservoir, the character tightens into narrower National Park gorge water.
Method
These are big, educated fish in clear water — treat every cast as your one shot. Streamers move the biggest trout, especially in low light; nymph the deeper pools methodically the rest of the time. The no-kill water is barbless, fish-from-the-net.
Kit
9 to 10 ft #5/6 for streamer work, 9 ft #4 for nymphing. 10-12 lb fluoro for streamers, down to 5X for nymphs in the clear pools. A net built for careful release — these fish deserve it.
Why this works
Good — water temperature is right today, though time of day could be better.
Backed by regional invertebrate surveys; no sampling on this exact reach yet.

Brown Trout fly box
A fuller Italian trout and grayling box for the southern Alps and northern limestone/alpine systems. It keeps the marble-trout streamer accent, but adds proper grayling dries and bugs, competition nymphs, caddis/olive work, terrestrials, pocket-water dries and alpine lake patterns.

Permits & access
Permit required — see local rules.
Regional Abruzzo fishing concession (tassa di concessione regionale, €22.72/year) plus identity document required as a baseline
Inside the National Park, additional Ente Parco permit and access conditions apply — confirm current terms at parcoabruzzo.it
The Castel di Sangro no-kill/CONI training water is barbless, catch-and-release.
The Sangro starts high under Monte Turchio inside the Parco Nazionale d'Abruzzo, Lazio e Molise, drops through narrow gorges past Villetta Barrea and the Barrea reservoir, and by the time it reaches Castel di Sangro it has built a reputation that draws fly anglers from well outside Italy — wild brown trout that regularly push two kilograms, big by any Apennine standard. A CONI-recognised training water and no-kill reserve runs between the town and the Ponte della Maddalena. This entry covers the upper, National Park reach only — the lower Sangro toward the Adriatic is a different, lowland river outside that scope. Fishing inside the Park boundary is further restricted on top of the regional calendar, so check the Ente Parco's own rules before you rig up.
