Quick Summary: Sunset is included in almost every standard Salar de Uyuni tour and is the easier, warmer and more sociable option. Sunrise requires a separate departure at around 03:00 to 04:00, costs extra and is punishingly cold, but gives you an emptier salt flat, better reflections on calm mornings and the option to combine it with star photography. If you only do one, do sunset; if you are travelling for photography, do both on consecutive days.
Almost every traveler arriving in Uyuni ends up on a sunset tour, because that is what the standard itinerary includes. Far fewer do sunrise, because it means leaving town in the dark at around 03:30 and paying for a second departure.
The honest answer is that they are different experiences rather than better and worse ones. This guide explains what each is actually like, what changes by season, and how to decide which fits your trip. For the wider seasonal picture, see our guide to the best time to visit the Uyuni salt flats.
The short answer
- Choose sunset if you have one day, want the standard experience, dislike extreme cold, or are travelling with children or anyone struggling with altitude.
- Choose sunrise if you are a photographer, want the flat to yourself, want to combine it with stars, or are already doing a 3-day tour that includes sunset on day one.
- Do both if you have two nights in Uyuni. This is the single best upgrade available and costs less than adding tour days.
How tours are actually structured
Understanding the standard departures makes the choice clearer.
| Tour type | Typical departure | Typical return | What you get |
|---|---|---|---|
| Standard 1-day tour | 10:00–10:30 | 19:00–20:00 | Train Cemetery, Colchani, open salt, Isla Incahuasi, sunset |
| Sunset + stars tour | 15:00–16:00 | 22:00–23:00 | Salt flats, sunset, night sky session |
| Sunrise tour | 03:00–04:00 | 09:00–11:00 | Night sky, sunrise, morning on the salt |
| Star + sunrise combined | 02:30–03:30 | 10:00–11:00 | Milky Way, sunrise, breakfast on the flat |
| 3-day tour, day one | 10:00–11:00 | Overnight at salt hotel | Standard day plus sunset before checking in |
Sunrise and star departures are almost always sold separately from the main 1-day tour, and prices differ between operators. Book them the day before in Uyuni town rather than assuming a departure will run — they need minimum numbers.
Sunrise at Salar de Uyuni
What it involves
You are picked up from your accommodation between 03:00 and 04:00, drive out to the flat in darkness, and wait. Most sunrise tours include a stop for stargazing on the way, because the salar sits at 3,656 m with almost no light pollution and the Milky Way is exceptionally clear on moonless nights.
Then the sky begins to lighten, and on the salt flat this happens in a way it does not elsewhere. There is no terrain, so the colour change fills the entire visible hemisphere. In the wet season, with water on the surface, it happens twice — once above you and once below.
What makes it good
- Emptiness. A handful of vehicles rather than dozens. At sunset you will share the flat with the whole day’s tour fleet.
- Calm air. Wind at Uyuni generally builds through the day and drops overnight. Still mornings give the cleanest mirror reflections in the wet season.
- Stars first. You get the night sky and the sunrise in one departure, which is excellent value for photographers.
- Breakfast on the salt. Most sunrise operators serve coffee and a simple breakfast out on the flat, which is a better memory than it sounds.
What makes it hard
- The cold. This is the coldest part of any 24-hour period at Uyuni. In June and July, pre-dawn temperatures on the flat frequently sit between −10°C and −15°C, and there is no shelter. Full winter layers, gloves and a hat are essential — see our Uyuni packing guide.
- The hour. Getting up at 02:45 at 3,670 m altitude, possibly on your first or second night there, is genuinely difficult.
- Battery drain. Expect to lose a large share of phone and camera battery to the cold before the sun is even up.
- Extra cost. It is a separate paid departure.
Sunset at Salar de Uyuni
What it involves
Sunset is the finale of the standard 1-day tour and of day one on a 3-day tour. You have already spent the day at the Train Cemetery, Colchani and out on the salt, and the driver positions the vehicle somewhere with clean sightlines for the last hour of light.
Most operators bring snacks, and in many cases a bottle of wine or a sparkling drink is produced as the sun drops. It is a sociable, relaxed way to end the day.
What makes it good
- No extra effort or cost. It is already included.
- Warmer. Still cold once the sun is down, but nothing like pre-dawn.
- Longer golden hour. The approach to sunset gives you a good 45 to 60 minutes of usable warm light, compared with a sharper transition at dawn.
- You are already warmed up. By late afternoon you have had a full day to practise perspective shots and figure out your exposure settings.
- Group atmosphere. If you have enjoyed your tour group, sunset is when the day comes together.
What makes it harder than people expect
- Crowds. Every tour on the salt that day converges on sunset. Getting a clean frame without other vehicles takes some negotiation with your driver.
- Wind. Afternoon wind is stronger, which in the wet season can ripple the water and break reflections.
- Temperature crash. The moment the sun goes down, temperature falls fast. People who packed for a sunny day regret it within ten minutes.
- Late return. You get back to Uyuni around 19:00–20:00, which matters if you have a night bus booked.

Seasonal timings at Uyuni
Uyuni sits at about 20.5°S, so day length varies noticeably but not dramatically. Approximate local times:
| Period | Sunrise (approx.) | Sunset (approx.) | Notes |
|---|---|---|---|
| June–July (dry winter) | ~07:00 | ~17:50 | Latest sunrise, earliest sunset, coldest nights, clearest skies |
| September–October | ~06:20 | ~18:30 | Shoulder period, reliable conditions |
| December–January (wet summer) | ~05:45 | ~19:10 | Earliest sunrise, latest sunset, mirror effect most likely, most cloud |
| March–April | ~06:30 | ~18:40 | Late mirror effect, variable cloud |
Two practical consequences. First, in June and July a sunrise tour departs at a more civilised hour in absolute terms but in far worse cold. Second, in December and January a 03:30 pickup for a 05:45 sunrise is a very early start — check the actual departure time with your operator rather than assuming.

Which is better for photography?
For photographers specifically, sunrise usually wins, for three reasons that have nothing to do with the light itself.
- Clean frames. Fewer vehicles means fewer 4x4s and strangers in the background of a wide shot. On a busy sunset this is the single biggest problem.
- Still water. In the wet season, the mirror effect depends on a surface with almost no ripple. Pre-dawn calm delivers that far more reliably than late afternoon.
- Two sessions in one. Milky Way work before dawn, then blue hour, then sunrise, in a single departure.
Sunset’s counter-argument is the extended golden hour, which gives you more time to work a composition, and the fact that you have already had the whole day to test settings. If you are shooting silhouettes or perspective photos with warm light, sunset is entirely adequate.
For technique across both, see our Uyuni photography tips.
Who each option suits
- Best for first-time visitors: sunset. It is included, it is easier, and it delivers the image most people have in their head.
- Best for budget travelers: sunset. No extra departure to pay for.
- Best for photographers: sunrise, ideally combined with a star session.
- Best for wet-season mirror-effect trips: sunrise, because calm water reflects better.
- Best for dry-season landscape trips: sunset, since there is no reflection either way and the warm light on white salt is the stronger image.
- Best for families and travelers with children: sunset, clearly. A 03:00 start at −12°C is not a family activity.
- Best for anyone struggling with altitude: sunset. Broken sleep at 3,670 m makes acclimatisation worse.
- Best for travelers with two nights in Uyuni: both.
Can you do both?
Yes, and it is the recommendation for anyone who cares about the salt flats beyond ticking them off. The practical pattern is:
- Arrive in Uyuni, sleep, acclimatise.
- Day one: standard 1-day tour finishing with sunset. Book your sunrise departure that evening.
- Night two into day two: sunrise and star tour, returning mid-morning.
- Rest in the afternoon, travel onward that evening.
This costs less than adding a day to a 3-day tour and gives you the salt flat in both its best conditions. If you are then continuing to the coloured lagoons and the Chilean border, the San Pedro de Atacama to Uyuni route page explains how the multi-day itineraries link up.
Cost and booking notes
Sunrise, sunset-and-stars and standard tours are all sold from agencies along Avenida Ferroviaria and around the clock tower in Uyuni town, and prices move with demand and season. A few points that hold regardless:
- Book sunrise departures a day ahead. They need minimum numbers and can be cancelled.
- Confirm the pickup time in writing or by message. Pre-dawn pickups are the ones that go wrong.
- Ask whether breakfast, hot drinks and a blanket are included.
- Pay in bolivianos. Bolivia is cash-heavy and dollar quotes have been unstable since the currency began floating in mid-2026.
- If you have a night bus or flight the same day, remember that a sunset tour returns to town around 19:00–20:00 and can run later.
FAQ
Is sunrise or sunset better for the mirror effect?
Sunrise, on balance. The mirror effect needs a thin, undisturbed film of water, and wind on the salar typically builds through the day and drops overnight, so the surface is usually calmest before dawn. That produces cleaner, sharper reflections. Sunset in the wet season is still spectacular and can produce stronger colour, but a breeze that ripples the surface will soften the reflection, and afternoons are more likely to be breezy. If the mirror effect is your main reason for visiting, book a sunrise departure and travel between roughly late January and March.
How cold is a sunrise tour at Salar de Uyuni?
Very cold. Pre-dawn is the coldest point of the day, and on the open flat in June and July temperatures commonly sit between −10°C and −15°C with no shelter of any kind. Even in the warmer wet-season months it is usually below freezing before sunrise. You need thermal base layers, an insulated jacket, gloves, a warm hat and proper closed shoes, plus something to sit or kneel on if you are shooting from low angles. Batteries drain quickly in these conditions, so keep spares in an inside pocket.
Do I need to pay extra for a sunrise tour?
Yes, in almost all cases. The standard 1-day tour includes sunset and returns to Uyuni in the evening, while sunrise departures are sold as a separate trip leaving in the early hours. Star-gazing sessions are usually bundled with either the sunrise departure or an evening sunset-and-stars tour rather than with the standard day trip. Prices vary between agencies and with season, so compare two or three in Uyuni town and confirm exactly what is included.
Can I see the stars and the sunrise on the same tour?
Yes, and it is the most efficient way to do both. Most sunrise departures leave between 03:00 and 04:00 and include time on the flat under the night sky before dawn breaks, which means one payment and one early start covers Milky Way photography, blue hour and sunrise. The main variable is the moon: a bright moon washes out the stars completely, so if astrophotography matters to you, check the lunar calendar and aim for dates close to the new moon.
If I only have one day in Uyuni, which should I choose?
Sunset, without much hesitation. It is built into the standard tour, so you see the Train Cemetery, Colchani, the open salt and Isla Incahuasi during the day and finish with the sunset you came for, all in one departure and one payment. Choosing sunrise instead on a single day means either missing the daytime stops or paying for two separate tours and spending most of the day tired. Save sunrise for a second day if your schedule allows it.
Limitations
Sunrise and sunset times shift through the year and the figures here are approximations for Uyuni’s latitude — check exact times for your travel dates. Whether a sunrise or star departure runs at all depends on operator demand and weather, and pre-dawn tours are cancelled more often than daytime ones. Cloud cover, moon phase and wind all affect what you actually see and none can be predicted more than a few days out. The mirror effect depends entirely on rainfall in a given week rather than on the calendar. Tour prices, inclusions and pickup times vary widely between agencies in Uyuni and change seasonally; Bolivia’s floating exchange rate since 26 June 2026 makes dollar quotes unreliable, so confirm figures in bolivianos shortly before you travel.
