Valley of the Moon Sunset Tour in Atacama Desert: Travel Guide

After a fun sunrise visit to El Tatio Geysers, Sam and I signed up for yet another tour. This one was a sunset tour of Atacama’s Valley of the Moon and I was pretty excited to see what magical landscapes the desert had to offer. Spoiler alert: sunset did not disappoint!

Our tour left San Pedro de Atacama at 4:00 p.m. and we had a very short drive ahead of us. The Valley of the Moon is located just 13 kilometres outside of town, so by the time we got comfortable in our seats, we were already there.

First Impressions of the Moon Valley: Why It’s Called “Moon Valley”

As soon as we climbed out of the truck it became pretty evident how the valley gets its name. In front of us lay an expanse of stone and sand formations carved by millennia of wind and water. Sprinkled like flour in a messy kitchen, there were white patches of salt which marked the remains of ancient lakes that have long since evaporated.

This is your iconic postcard shot of Atacama,” our guide said as we pulled up to the canyon’s ridge and looked out at the Cordillera de la Sal which stretched out before us.

Snap, snap, snap!

Exploring the Salt Caves: Entering the Cañon de Sal

After going trigger-happy at the sight of the canyon, we continued on to the salt caves, also known as Cañon de Sal. When our guide asked us if we were claustrophobic back in town, I thought we might be crawling through some narrow spaces, but then he really downplayed it on the drive over and I completely forgot that the caves were even on the itinerary.

The tour of the salt caves started out easy enough. We entered a gorge that didn’t seem all that impressive at first glance, but it grew narrower and narrower the deeper we walked in, until it finally became a dark tunnel. Our guide had asked everyone on the truck to bring their cellphones along so we could look at the salt crystals, but once we were in the tunnel, it turned out that we really needed the cellphones as flashlights.

The thing about that tunnel is that once you’re in there, there is no turning back. The space is only wide enough for a group to snake through in a single file, so if you change your mind,  you’re blocked in by those behind you. Not all of us had brought our cell phones out to the desert so there was a bit of stumbling, crawling, and blindly feeling our way around, but when we finally emerged we were met with a landscape that resembled Mars (or at least it looked a lot like the scenes from The Martian!)

Pretty dazzling, right?

Watching the Valley of the Moon Sunset: The Final Climb

By then, we were getting close to sunset, so it was time to hop back in the truck. We took a short detour to visit some salt flats and from there we hiked up to a ridge to watch the sun do its magic.

The wind was whipping our hair and blowing sand in our faces by the time we reached the top, but as far as sunsets go it was a pretty spectacular one.

On the way back our guide let us climb on top of the truck and ride with the cool evening breeze blowing in our faces. We had to climb back down once we approached the town, but it was a pretty nice way to finish up our sunset tour of the Atacama Desert, Chile.

Tips for visiting the Valley of the Moon at sunset:

• • Wear shorts. Afternoons in Atacama are really hot, and while it does cool down towards sunset, it’ll be nowhere near the freezing temperatures you experience in the desert in the early morning. I was perfectly fine in shorts and I just made sure to bring a sweater for later in the day.
  • Bring lots of water. Our guides insisted that we each carry a 1L bottle of water (they even made people run to the convenience store before heading out on the tour), and I was glad we had them. It may seem like a hassle to lug a bit bottle around, but you’ll be glad once you’re out in the scorching sun.
  • Shield yourself from the sun. Don’t forget to wear sunblock, a hat, and sunglasses.
  • Choose your footwear wisely. Closed shoes are best for this activity. You’ll be crawling through caves, hiking up rubbly slopes, and trekking through a few sandy stretches.

The four tips above are the ones you really do need — everything else I wish I’d known before our guide handed us water bottles in the car park. Here’s the fuller picture for anyone planning this tour.

Why the Sunset Here Is So Spectacular

Valley of the Moon is already otherworldly, but late-day light turns the ridges and dunes into a living painting. As the sun sinks, ochres become ambers, whites turn to blushing pinks, and the Cordillera de la Sal glows like a kiln. Add wind-whipped sand for drama and a bonus afterglow that lingers long enough for photos without harsh shadows. It was genuinely one of the best sunsets I’ve watched anywhere.

Guided Tour or DIY?

You can hire a tour in San Pedro de Atacama (most leave around 3–4 pm), or head out yourself by bike or rental car. Quick comparison:

What a Typical Sunset Tour Looks Like

Exact stops vary by operator, but a common flow looks like this:

• 15:30–16:00 — Hotel pickup in San Pedro, quick headcount and “you brought water, right?” talk.
• 16:15 — Park entry and first vista of the Cordillera de la Sal (cue 200 photos in 2 minutes).
• 16:45 — Cañón de Sal / salt caves walk: squeeze, duck, marvel, emerge into that “are we still on Earth?” amphitheatre.
• 17:30 — Micro-hike to a ridge for changing colours; snack stop if included.
• 18:15–19:30 — Golden hour to sunset to afterglow. Wind picks up — hold onto your hat and your jaw.
• Return — Post-sunset drive, first stars beginning to appear; arrive back in town early evening.

What to Pack

Desert Necessities

• 1–1.5 L water per person (minimum)
• Sunscreen (high SPF) and lip balm with SPF
• Hat with a brim (chin strap if you have one — wind!)
• Sunglasses (polarised work well here)
• Light sweater or windbreaker for the post-sunset chill
• Closed shoes with grip (trail runners or light hikers)

Nice-to-Haves

• Neck gaiter or scarf to shield from blowing sand
• Headlamp or phone light for the caves and afterglow
• Snacks (salty beats sweet at altitude)
• Small first-aid kit (plasters, pain relief)
• Cash for park entry or extras if you’re going DIY

Photo Kit

• One wide-to-mid lens (24–70mm covers most situations)
• Microfibre cloth (wind and dust make a smudgy lens very quickly)
• Mini tripod for blue-hour sharpness
• Extra battery (cooler temperatures drain faster than expected)
• Phone backup with RAW or HDR enabled

What to Wear by Season

• Summer (Dec–Feb): Hot afternoons — a breathable tee and shorts work. Add a long sleeve for the breeze on the ridge.
• Shoulder seasons (Mar–May and Sep–Nov): Layers are essential. Quick-dry pants, tee, light fleece, wind layer.
• Winter (Jun–Aug): Sunny but the wind bites. Base layer, mid layer, shell; a beanie for after the sun drops.

Safety and Etiquette

• Stay on marked paths. Dunes and salt crusts are delicate — one footprint can last months out here.
• Watch the wind. Gusts can be sudden; keep cameras leashed and hats secured.
• No drones. This is a protected area and rangers enforce the rule.
• Carry in, carry out. Even “biodegradable” orange peels don’t belong here.
• Caves: If you get anxious in tight spaces, tell your guide early — there’s usually an alternate path to rejoin the group.

Photography Tips

Work the Light

• Golden hour: Side-light those ridges to bring out the texture; backlight for glowing edges.
• Blue hour: Tripod plus low ISO gives crisp, cinematic layers; the salt turns silvery and beautiful.

Compose for Drama

• Leading lines: Use dune spines and ridgelines to pull the eye towards the volcanoes on the horizon.
• Scale: Include a tiny human on a distant ridge (on-trail only) to show the vastness.
• Foreground interest: Salt crystals, cracked clay, a line of footprints in the sand.

Camera Settings to Start With

• Landscape: ISO 100–200, f/8–f/11, shutter as needed (raise ISO if wind is shaking things).
• Handheld in wind: Aim for 1/250s or faster; brace against rocks and exhale as you click.
• Phone shooters: Turn on grid, tap to lock focus and exposure, use HDR, and prop your phone on a rock for sharp blue-hour frames.

The Main Viewpoint Types

• Drive-up ridges: Sweeping views with minimal walking — maximum wow, accessible for everyone.
• Micro-hikes: 10–30 minutes on uneven ground for unique angles and fewer people in frame.
• Salt canyon walls: Narrow corridors where light bounces into peachy-pink walls — keep that phone light handy.
• Sand dune S-curves: Check for any closures on arrival; when open, stick to existing tracks to protect the crest.

Sunset vs. Sunrise

If you’re a photographer, sunset for colour and sunrise for serenity is the ideal combination if you have two mornings here.

When to Go: Seasons and Moon Phases

• Year-round: The dry desert means a sunset visit is on the table every month.
• Wind: Afternoons can be breezy; spring tends to be gustier — bring a shell.
• Winter nights: Crisp and cold once the sun drops; bundle up.
• Moon phases: For star photos after sunset, aim for a new moon. For silver-lit landscapes, a waxing or waning gibbous can look spectacular.

Budgeting and Booking

• Most tours include: Transport, guide, park logistics, sometimes a snack.
• Usually not included: Your personal water, tips, extra layers — bring your own everything.
• Book early in high season (December to February and July), especially for small groups or private guides.
• Questions to ask your operator before booking:
  • How many stops and how long at each?
  • Does the tour include the salt caves, and can I skip them if I’m claustrophobic?
  • What’s the maximum group size?
  • Do you supply lights or snacks, or should I bring my own?

Good Day Combinations from San Pedro

• Geysers and Moon Valley (our day): El Tatio at sunrise → nap and brunch → Valley of the Moon at golden hour. A full day and completely worth it.
• Lagoons and sunset: Laguna Cejar float or Baltinache in the morning → lazy lunch → Moon Valley glow.
• Culture and craters: Quitor Pukará and Tulor ruins plus a town wander → Moon Valley in the late afternoon.

Leave No Trace in the Atacama

• Stay on durable surfaces.
• Pack out all trash, including tiny wrappers.
• Respect wildlife and other visitors’ space.
• Take only photos; leave the crystals and stones exactly where they are.
• Honour any closures — they protect what you came to see.

Where to Stay in San Pedro de Atacama

Tours depart from and return to San Pedro, so your hotel is genuinely your base of operations for everything in the Atacama. Two well-reviewed options include:

• Terrantai Lodge — In the historic centre of San Pedro, very quiet, breakfast included, and the staff are specifically praised for their local recommendations (helpful when you’re trying to choose between sunrise and sunset tours).
• Pascual Andino — 100 metres from Caracoles, the main street, so everything is right there — tour agencies, restaurants, your hotel. Buffet breakfast included, free WiFi, free parking.

Valley of the Moon FAQ

How far is Valley of the Moon from San Pedro de Atacama?

Roughly 13 kilometres — about 20–30 minutes by vehicle depending on stops. Minimal transit time means more time on the ridge.

Can I visit without a guide?

Yes. Self-drive is common. Check entrance hours, bring cash and water, and plan your exit to beat closing time. Cycling is possible but wind and darkness after sunset make a return light essential.

Are the salt caves mandatory?

No. If tight spaces aren’t for you, tell your guide — there’s usually an alternate path to rejoin the group for the main views.

Will I feel altitude sickness?

San Pedro sits at around 2,400 m (7,874 ft). Most visitors feel fine, but pace yourself, hydrate, and avoid big exertion if you just arrived. Save harder activities for day two.

What’s the best footwear?

Closed-toe shoes with decent grip — trail runners or light hikers. Sandals and salt caves are a combination that ends in regret.

Can I fly a drone?

No. Drones are prohibited to protect wildlife, visitors and fragile landscapes. Rangers enforce this rule.

How windy does it get?

Afternoon winds are common — sometimes a gentle breeze, sometimes quite persuasive. Bring a wind layer, keep gear strapped, and shield your camera lens when swapping in dusty conditions.

What if the sky is cloudy?

Often even better for colour and texture — clouds catch fire at sunset. Only heavy dust storms or the rare rain would genuinely dampen a visit.

Is there drinking water inside the park?

No. Bring your own — a minimum of 1–1.5 L per person. The desert is dryer than it feels and you’ll be glad you brought it.

What about restrooms?

Expect basic facilities near main entrances or parking areas. There are no mid-trail options, so go when you can.

Can families with children do this tour?

Yes — stick to shorter walks, bring sun protection and snacks, and keep young explorers on designated paths. Cliff edges can be closer than they look.

Is stargazing possible right after sunset?

You’ll catch a few bright stars after civil twilight, but the full Atacama sky show kicks in later. A dedicated night astronomy tour back in San Pedro — with telescopes and expert guidance — is worth adding to the trip.
