Is there a tourist tax per night in Moroccan riads?

Yes, Morocco charges a small nightly tourist tax (taxe de séjour) per person, typically a few dirhams up to around 25–30 MAD depending on the town and the standard of the accommodation, and it’s usually paid in cash at checkout. It often isn’t included in the online room price, so budget a little extra.

The exact amount varies by city and by the classification of the riad or hotel, with smarter places charging more per person per night. Children under a certain age are commonly exempt.

It’s a minor cost but a near-universal one, so keep some cash for it at checkout even if you paid for the room by card. Ask when you check in so there are no surprises at the end.
