What currency is used in Merzouga? Are there ATMs?

Cash in Moroccan dirhams (MAD) rules here — the nearest reliable ATMs are in Rissani and Erfoud, so withdraw before you arrive.

Merzouga’s own ATM situation is unreliable enough that no one should count on it. Budget cash for activities, tips, drinks and souvenirs; euros are accepted at many camps at honest rates.
