Permits & access
Permit required — see local rules.
- Permis de pêche (fishing permit) — locally issued
- Foreign anglers should contact the local HCEFLCD delegation or a Moroccan fishing guide for the area they plan to visit
- The permit system is not standardised for visitors in the way European systems are — expect local arrangements rather than an online purchase process
- A guide familiar with the area is strongly recommended for both practical access and permit logistics.
