Hidden in the lush Belgian Ardennes, the Lesse River is a fly angler’s dream—crystal-clear waters winding through dense forests and dramatic cliffs. This picturesque setting isn’t just for hikers; its gentle currents and thriving trout and chub populations make it ideal for wading with a rod.
Tactics vary by season: dry flies dance on summer evenings, nymphs tempt in cooler flows, and even oversized wooly buggers surprise feisty trout. Start your adventure near the village of Lesse (note: ignore Google Maps’ mislabeling—it’s the Lesse, not "Lomme"). Park by the BBQ spot, gear up, and wade upstream for easier access or downstream for secluded riffles—just watch for rocks and shifting water levels.
Licenses Made Simple:
- A Wallonia fishing permit is mandatory (details here).
- For this stretch, secure a day (€5) or annual (€25) pass from Amicale Des Pecheurs de Redu—email Manu (French-friendly via Google Translate) at fhpsbl.be.
Beyond This Beat:
Explore more of the Lesse and Ardennes’ rivers via fhpsbl.be or maisondelapeche.be. While some public spots allow fishing with just the regional license, prime fly waters often require local permits—persistence (and translation apps) unlock secluded gems.

Pro Tip: Evening hatches near picnic areas can yield surprises when crowds thin. Pack light, tread carefully, and let the Ardennes’ beauty hook you as deeply as its fish.
