Most travellers planning their first stay in the "Moroccan desert" imagine a continuous expanse of golden dunes.
The geographical reality is different, and knowing it concretely changes how you plan a trip.
Is the Moroccan desert entirely made of sand dunes?
The term "desert" actually covers two very different landscapes.
The reg is a plain of stones and gravel, flat as far as the eye can see — it is the most widespread form of desert in Morocco, but also the least photogenic and therefore the least associated with the word "desert" in the popular imagination.
The erg, by contrast, refers to a true sea of sand dunes — the landscape sought by almost every traveller.
These ergs represent only a fraction of the Moroccan desert territory, concentrated in specific areas rather than spread evenly.
This distinction is not just a geographical detail: it also explains why some photos published online, taken from a road crossing the reg, look nothing like the usual image of the "Moroccan desert".
The real spectacle of the dunes only begins once you reach one of the two main ergs.
What are the main accessible ergs in Morocco?
Erg Chebbi, near Merzouga, remains the most visited: about 560 km from Marrakech, dunes reaching 150 metres in places, and the country's most developed tourist infrastructure for this type of stay.
Erg Chegaga, near Zagora, offers a vaster but less accessible erg, with fewer accommodation options.
For a detailed comparison between the two, our Merzouga or Zagora guide details the choice criteria based on your travel profile.
Other desert areas exist further south and east in Morocco, but remain largely undeveloped for tourism, without accommodation infrastructure comparable to Merzouga or Zagora.
This concentration of tourist offer on just two sites is no coincidence: it reflects decades of local investment in access roads, camps and guides trained specifically for these two regions.
Venturing beyond these areas requires considerably more complex logistics, reserved for experienced travellers.
What is the difference between the Sahara and the Moroccan desert?
The Moroccan desert is part of the Sahara, the largest hot desert in the world, stretching across several North African countries — Algeria, Libya, Egypt, Mauritania and beyond.
Morocco occupies only a north-western fringe.
This perspective helps explain why a trip "to the Sahara" from Marrakech is in fact limited to a small part of the total desert, yet enough for a complete immersion: dunes, silence, starry sky, without needing to travel to another country.
According to data published by the Moroccan National Tourist Office, the relative accessibility of the Moroccan Sahara from the country's big cities largely explains its popularity with international travellers, compared to other parts of the Sahara that are far harder to reach.
By comparison, reaching a section of the Sahara in Algeria or Mauritania from Europe generally involves several extra days of travel and far more complex administrative procedures.
Morocco remains, in this regional context, one of the simplest gateways to a genuine Saharan experience.
What does this reg/erg geography mean for planning your trip?
Understanding this reg/erg distinction avoids a common disappointment: some tours sold as "desert" in fact cross mostly reg, with only a final stretch of true erg.
Checking that a night in a desert camp in the dunes is actually included — not just a vehicle crossing — remains the key point to clarify before booking.
The journey itself almost always crosses several successive landscape types: High Atlas mountains, palm groves, reg plains, before finally reaching the erg — a progression that is an integral part of the experience, not just a transfer between two points.
It is precisely this diversity of landscapes that distinguishes a genuine Moroccan desert tour from a simple there-and-back to a sand beach: mud-brick kasbahs, rocky gorges and green oases unfold before arriving at the dunes, each adding its own breathing space to the trip.
A traveller in a hurry, who only wants the final image of the dunes, may be tempted to skip these intermediate stops.
Those who take the time to stop often leave with a more complete memory of Morocco, not just of a desert cut off from the rest of the country.
Practical tip
Before booking a "Moroccan desert" tour, ask specifically whether the programme includes a night in a desert camp in a true dune erg, rather than simply crossing the reg by vehicle.
