When is the best time?

Peak: 15 Sep – 5 Oct. Second half of September into the first days of October; 2026 started early (first days of September) after a hot dry summer

Active from 5 Sep to 15 Oct (September to October) in a typical year.

Time of day

Roaring starts at dusk and runs through the night, with the second peak from an hour before dawn to sunrise. Cold, still nights after rain are best. Note that sensitive sectors of the Saint-Hubert forest are closed from 17:30 to 08:00 during the rut, so evening listening there is from the signed public listening spots and roads.

What will you hear?

Stags roaring in the beech and spruce valleys of the Ardennes — long, hoarse groans answered across the ridges, antler clashes in the dark, boar grunting, tawny owls; valleys give long reverb.

Binoculars?

No binoculars needed. You listen; stags are rarely seen in the forest. The DNF observation platforms at Saint-Hubert give occasional views at dusk; no torches.

Where to go

How to go on your own, and what it costs

Go to the signed public listening spots in the Grande Forêt de Saint-Hubert (the regional environmental-education centres publish a map of free listening spots in the season) in the last hour of light, by car to the marked car parks then on foot along forest roads; sensitive sectors are closed at night and battue days are posted. Sectors closed at night can only be entered on the public listening evenings organised by the forest service and the regional environmental-education centres.

Cost: Free from the public listening spots; public listening evenings run by the forest service / environmental-education centres charge a few euros (check current dates and prices).

Free or no-guide alternative: Use the free marked listening spots around the Saint-Hubert massif and forest roads outside the closed sectors in the hour after sunset — no guide needed; respect closures and keep torches off.

Who runs access

Field-recording notes

Wallonia's forests are public but during the rut the DNF closes sensitive sectors (17:30–08:00 in the Saint-Hubert massif) and marks the open listening points — respect the pictograms, stay on roads and tracks, no torches (the deer flee and the rut stops), no calling or playback. Stand-hunting opens around 21 September and battues from 1 October with signed closures: read the yellow notices before going in at night. Noise: the N89/E411 corridors are audible in parts of the Saint-Hubert forest; Anlier and the Lesse valleys are quieter. Frost brings the clearest nights and the longest carry.
