How to fish it · for Grayling
When
Autumn through November prime.
Where
Faster runs and gravel reaches through the middle and lower stretches.
Method
Euro-nymphing through the deeper pockets is the daily default; switch to dries on autumn afternoons when sedges and small olives come off. Long fine tippet for the clear water.
Kit
10 ft #3 nymphing rod for the deep pockets; 9 ft #4 for dries. 4 to 5 lb fluoro tippet, 12 ft leader.
Why this works
Good — water temperature is working for you, but time of day is the limiting factor today.
Likely species
Stoneflies

Beats · 2 · 1 reaches

The Andelle is mostly association water under AAPPMA permits, not a chain of estate beats. The one well-documented fly reach is a public, bookable no-kill parcours; a private stretch at a country-house hotel is fished by its guests. Always confirm rules and availability with the controller.

The 2 beats
Radepont fly parcoursDay tickets
AAPPMA La Mouche Charlevalaise
A public, no-kill fly reach through a château park at Radepont, run by the local fishing association. It is booked in advance online, by the day, rather than through a beat agent.
Fly only and no-kill. Hook and streamer rules were not confirmable from a primary source, so check them when you book.
Visit official site ↗
Manoir de Malvoisine (hotel guests)Private
Manoir de Malvoisine
A private beat of roughly a mile belonging to a country-house hotel and, as far as we can tell, fished by hotel guests rather than sold to the public.
Permits & access
Permit required — see local rules.
  • AAPPMA permits
  • Some beats are private/estate water — verify access.
