In short: A one-way Morocco desert tour drops you in a different city than you started (for example Marrakech to Merzouga, then onward to Fes), so you never backtrack the same road twice. A round-trip loops you back to your starting point. Choose one-way when your onward flight or route is elsewhere; choose round-trip when your bags, hotel, or return flight sit in the city you left.
What is a one-way Morocco desert tour?
On a one-way desert tour you travel in a straight line rather than a loop. The classic version starts in Marrakech, crosses the High Atlas over the Tizi n’Tichka pass, spends a night at the Erg Chebbi dunes near Merzouga, then continues north and finishes in Fes instead of doubling back. It works the other way too, Fes to Merzouga to Marrakech. The whole point is that you see fresh scenery every hour instead of retracing the Draa Valley or the Dades gorges twice. When I did the Marrakech-to-Fes version, the second half through the Ziz Valley palm groves felt like a completely different country from the red gorges of day one.
How far and how long is each route?
Distances matter here because Morocco is bigger than it looks on a map. Marrakech to Merzouga is roughly 560 km and 9-10 hours of driving, which is why the Merzouga trip is almost always sold as 3 days and 2 nights, not a rushed overnight. Fes to Merzouga is shorter, about 470 km and 7-8 hours, so a one-way tour that ends in Fes shaves real time off your final leg. If you only have two days, the Zagora route (Marrakech to Zagora, about 360 km and around 7 hours each way) is the honest choice, though its small dunes near the M’Hamid edge are nothing like the towering sand at Erg Chebbi, whose tallest dunes reach roughly 150 m.
Which saves you time and money?
A shared 3-day group tour to Merzouga typically runs about 80-150 EUR per person, and that price is usually the same whether the tour ends back in Marrakech or drops you in Fes, because the driving distance is comparable. So a one-way tour rarely costs more. Where it saves you is downstream: if your trip continues to Fes, Chefchaouen, or a flight out of Fes airport, ending there skips a second long transfer south. Round-trip can be cheaper overall only when your hotel and return flight are both in your starting city, so you avoid paying for a new base at the far end.
When does round-trip make more sense?
Round-trip wins when logistics anchor you to one city. If you left luggage at a Marrakech riad, have a non-refundable return flight from Marrakech-Menara, or booked several nights there before and after the desert, looping back is simply cleaner. Round-trip also suits travelers who want to stop at the same highlights on the return, such as the Ait Benhaddou kasbah or the Ouarzazate film studios, on a slower schedule. The trade-off is that you spend a full extra half-day on roads you have already seen.
Is Agafay a one-way or round-trip alternative?
Neither, really, and it is worth clearing up. The Agafay desert is a rocky, stone desert about 40 minutes from Marrakech, not a sand-dune sea. There are no Erg Chebbi-style dunes there. Because it is so close, Agafay is almost always done as a round-trip half-day or overnight from Marrakech, not a point-to-point crossing. If your dream is climbing 150 m dunes and riding a camel into a sand horizon, you need Merzouga or the remote Erg Chigaga near M’Hamid, reached by 4×4. If you just want a quick starlit dinner near the city, Agafay is the round-trip answer. For the full picture, see our Morocco Desert guide.
Best season and practical tips
The comfortable window for either format is October to April. Summer daytime heat regularly pushes past 40C in the desert, which makes long transfers punishing, while winter nights on the dunes get genuinely cold, so pack a warm layer even in a warm month. Whichever direction you choose, confirm the drop-off city in writing before you pay, ask whether the price is per person or private, and check that the overnight camp near Erg Chebbi is included rather than an add-on. Our related guide covers what to expect at the camp itself.
Frequently Asked Questions
Does a one-way Morocco desert tour cost more than round-trip? Usually not. A shared 3-day Merzouga tour runs about 80-150 EUR per person either way, since the driving distance is similar whether it ends in Marrakech or Fes.
Can I start in Fes and end in Marrakech? Yes. The one-way route runs in both directions. Fes to Merzouga is about 470 km, and continuing to Marrakech afterward is the longer leg at roughly 560 km.
Is two days enough for the big dunes? Not really. A 2-day tour realistically only reaches Zagora’s smaller dunes. The tall Erg Chebbi dunes at Merzouga need a 3-day, 2-night trip because of the 9-10 hour drive.
Can I do a one-way tour into Agafay? No. Agafay is a rocky desert 40 minutes from Marrakech and is done as a round-trip outing, not a point-to-point crossing.
What is the best time of year? October to April. Summer daytime heat tops 40C, and winter desert nights are cold, so bring a warm layer regardless.
