Quick answer: Stargazing in the Sahara desert of Morocco is best in the dunes of Erg Chebbi near Merzouga, far from city lights, on nights close to the new moon. The Milky Way core is brightest from roughly April to September, while winter brings crisper air and colder nights. A night at a desert camp, walking a few minutes away from the tents, is all you need.
Every evening, once the dinner tagine is cleared away and the drums at camp go quiet, we walk our guests a few hundred metres into the dunes and ask them to switch off their phones. Within ten minutes their eyes adjust, and the sky above Erg Chebbi fills with more stars than most of them have ever seen. This guide is our honest, practical take on how to get the most from a night under the Saharan sky.
Why the Sahara Is So Good for Stargazing
Three things make the desert around Merzouga exceptional for looking up. First, there is almost no light pollution. The nearest real town, Rissani, is about 35 km away, and Errachidia, the regional capital, lies roughly 130 km to the north-west. Once you are behind the first line of dunes, the small glow of Merzouga and Hassilabied disappears.
Second, the air is extremely dry. Humidity in the eastern Moroccan Sahara is low for most of the year, so there is little haze to scatter light. Third, clouds are rare. Merzouga sees only a handful of rainy days a year, mostly in late autumn and winter, which means the odds of a clear night are high whatever month you visit.
When to Go: Moon, Season and Meteor Showers
Follow the moon, not just the calendar
The single biggest factor is the moon. A full moon over the dunes is beautiful in its own way (the sand glows silver and you can walk without a torch) but it washes out all but the brightest stars. For deep-sky stargazing, aim for the week either side of the new moon. If your dates are fixed, check the moonrise time: a waning moon that rises after 1 am still leaves you a dark evening.
Season by season
| Season | Night temperature at camp | What you will see |
|---|---|---|
| Spring (Mar–May) | 10–18 °C | Milky Way core rising before dawn, then by late evening from May |
| Summer (Jun–Aug) | 22–30 °C | Milky Way core high overhead in the evening, Perseid meteors mid-August |
| Autumn (Sep–Nov) | 12–22 °C | Milky Way setting in the west after dark, very comfortable nights |
| Winter (Dec–Feb) | 0–6 °C | Orion, the Pleiades and Sirius; Geminid meteors mid-December; longest, darkest nights |
The famous Perseid meteor shower peaks around 12–13 August and the Geminids around 13–14 December. In a year when either peak falls near the new moon, a night in the dunes can deliver dozens of meteors an hour. Summer nights are warm enough to lie on a blanket until midnight; in winter you will want a down jacket, hat and the camp's heavy blankets.
What You Can See Without a Telescope
You do not need special equipment. With the naked eye on a moonless night you can expect to see:
- The Milky Way as a textured band, with dark dust lanes clearly visible in summer.
- Planets such as Jupiter, Saturn and Venus, which shine steadily rather than twinkling.
- Satellites crossing the sky every few minutes just after sunset, including the International Space Station on some evenings.
- The Andromeda Galaxy as a faint smudge in autumn and early winter, about 2.5 million light-years away.
- Star clusters like the Pleiades, which the Amazigh (Berber) people of the south have long used to track the seasons.
A pair of ordinary binoculars (8x42 or 10x50) makes a surprising difference: Jupiter's moons, the craters of the moon and the star clouds of Sagittarius all pop into view. If you have them, bring them.
How We Plan a Stargazing Night in Erg Chebbi
Most of our guests combine stargazing with an overnight stay in the dunes. The simplest option is our sandboarding and stargazing evening in Erg Chebbi, where we spend the late afternoon sliding down the slopes and then settle on a high ridge as the first stars appear. It is also the natural finale to a sunset camel trek to camp, since you arrive at the tents just as twilight fades.
Our routine is simple:
- We check the moon phase and weather when you book and suggest the best night if your dates are flexible.
- After dinner, we walk a few minutes beyond the camp lights to a dune crest with an open horizon.
- Your guide points out the main constellations and planets and shares the Amazigh names and stories we grew up with.
- We bring blankets and mint tea, and you stay out as long as you like.
If you are an early riser, the best of both worlds is to go to bed after stargazing and set an alarm for dawn. The walk up a dune for sunrise over the Merzouga dunes starts under the last stars.
Photographing the Desert Sky
Modern phones can capture the Milky Way in night mode if you keep them perfectly still. For better results with a camera:
- Use a tripod or wedge the camera into the sand with a folded scarf underneath.
- Choose your widest lens and open the aperture fully (f/2.8 or wider if possible).
- Start with ISO 3200 and a 15–20 second exposure, then adjust.
- Focus manually on a bright star using live-view magnification.
- Include a dune ridge or a camel silhouette in the foreground for scale.
Keep your camera in a bag when not shooting: fine sand gets into everything, especially when the wind picks up in spring.
Practical Tips for a Comfortable Night
- Dress in layers. The desert loses heat quickly after sunset; even in October the temperature can drop 15 degrees within a few hours.
- Use a red light. A red-filtered torch (or a phone set to red) protects your night vision. White light resets your eyes for about 20 minutes.
- Stay close to your guide. Dunes look alike at night. Never wander off alone without knowing the direction of camp.
- Avoid alcohol and heavy meals if you plan to stay up late. Hydration matters even at night.
- Download a star app before you arrive, since mobile signal in the dunes can be patchy.
Combining Stargazing with the Rest of Your Trip
Merzouga is a long way from the big cities: about 560 km from Marrakech and 470 km from Fes, which is why most people see it on a multi-day tour through Ouarzazate, the Dades Valley and the Todra Gorge. We usually recommend at least one night in the dunes and, if you are serious about the sky, two nights so you have a backup if the wind blows up dust. The second day can be filled with a 4x4 loop to Khamlia and Rissani or a relaxed morning in Hassilabied.
