Piave

Veduta dal Parco del Piave a Fener (BL)

Two hundred and twenty kilometres of water, and the stretch that matters for fly fishing runs through Belluno and down to Longarone, where the Piave settles into cold, clear Dolomite limestone current — proper marble trout water, with brown trout on the seams and grayling showing in the Belluno currents for anyone patient enough to spot them.

How to fish it · for Grayling
When
16 April to 28 September — a later opener than the trout season. Autumn afternoons through September are prime before the close, but check your permit type before assuming you can keep one.
Where
Faster currents and riffle heads through Belluno, where the pipam.it fishing reports describe grayling holding among rainbow trout in the central flows.
Method
Euro-nymph the faster water; small dries when naturals show on calmer afternoons. Daily and multi-day permit holders cannot retain grayling on the Busche-to-province-end reach at all — treat it as catch-and-release unless your permit says otherwise.
Kit
10 ft #3 nymphing rod, 4 to 5 lb fluoro tippet; 9 ft #4 for dries. 12 ft leader.

Ranked for today
Grayling 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.

About this water

Two hundred and twenty kilometres of water, and the stretch that matters for fly fishing runs through Belluno and down to Longarone, where the Piave settles into cold, clear Dolomite limestone current — proper marble trout water, with brown trout on the seams and grayling showing in the Belluno currents for anyone patient enough to spot them. It's a big river with a gorge country temperament, wide in places, tight in others; read it in sections rather than treating it as one long run.

    Temolo (grayling) closed from the last Monday of September to 15 April (R.R. 1/2023 art. 29) — later opener than trout. Minimum size 30cm. On the reach from the Busche dam to the end of the province, capture and retention is banned outright for anyone fishing on a daily or multi-day permit, regardless of season — check which permit type covers your beat before assuming grayling are fair game.

    Rules are set at province or association level — check locally.
