Key Takeaways
- The two main access points to Peru’s Rainbow Mountain are Cusco to Vinicunca and Cusco to Palcoyo, each with different hike lengths and difficulty levels.
- The classic Vinicunca route is steeper and higher, with a hike of about 6 to 7 kilometers round trip and a peak altitude of around 5,000 meters, so it suits travelers who are fit and well acclimated to altitude.
- The Palcoyo route is shorter and gentler, with easier walking, lower altitude, and several colorful mountains in one area, so it works better for families, older travelers, or anyone worried about altitude sickness.
- Guided tours from Cusco are the most practical option, since they handle transport, local guides, entrance fees, and usually meals, and they pick you up very early in the morning to avoid crowds and strong afternoon weather.
- The best time to visit Rainbow Mountain is during the dry season from May to September, with early morning starts helping you find clearer skies, fewer crowds, and more stable trail conditions.
“We arrived guys. Time to enjoy this beautiful view!”, said Rolando, our guide, once we made it to the top.
And from there we could see that strange phenomenon that almost every traveler in Cusco is talking about: the rainbow mountains (or “montaña de colores” as the Peruvians call it).
Yeah, you heard me right. I said “mountains” (plural) because on this tour you can see various rainbow mountains, not just one.
And the best part about it: you don’t have to hike 3 hours as the majority of people that take the famous tour to the Vinicunca rainbow mountain.
Cusco’s New Star: The Rainbow Mountain
The rainbow mountain(s) made it on the list of the top things to do in Cusco. In fact, with more than 600 visitors per day, the 5200m Vinicunca rainbow mountain is on a good way to catch up to the Machu Picchu that currently counts more than 4 times as many visitors per day.
On top of the Vinicunca Rainbow Mountain
So how come the rainbow mountains have become so popular? And what about the route that almost nobody knows yet (although it has many advantages over the tour to the Vinicunca)?
You won’t believe me but even though local tourist guides have discovered the rainbow mountain around 2 years ago, it is still not part of the most recent version of the Lonely Planet, neither of the most popular Peru-tours offered by foreign tourist agencies.
As a result, many travelers actually miss out on this highlight when visiting the country of the Incas.
The locals living close to the Vinicunca just kind of enjoyed the nowadays famous mountain, that is red as iron, yellow as sulfur and green as copper, for themselves. Can’t blame them I guess…I mean, who wouldn’t want to have a rainbow mountain in their backyard?!
Just recently through the distribution of spectacular photos on Facebook and Instagram more and more travelers want to discover the new tourist magnet for themselves and get their own stunning Instagram-picture.
Even though many of the photos are heavily edited, the natural colors of the rainbow mountains are still very impressive in real life.
When to Visit the Rainbow Mountain?
This natural beauty wears its shiny colorful rainbow-dress all year long, but everyone knows that between November and May “winter is coming”.
And this winter brings rain and snowfall, in the worst case, covering the Rainbow Mountain in white for days.
I would not advise doing the tour under these conditions as it is very probable that you won’t find what you are looking for: the 7-colored rainbow mountains.
So before talking about the -in my eyes- best route to get to know the rainbow mountains, let’s first take a look at the common Vinicunca trek that more than 90% of daily tourists take.
The Conventional Tour to the Rainbow Mountain Vinicunca
As for every trip I do, I checked what other travelers said about the rainbow mountain tour on TripAdvisor.
I found various travelers complaining about the bus ride, about guides making their group hurry up during the hike because their timetable was super tight and -especially- about problems with the altitude while hiking for 3 hours.
It seems like some agencies group their travelers and charter a bus for like 30 people where the driver is the tour guide at the same time.
Take a look for yourself and make sure you choose the right tour operator with good reviews so that your experience can be as breathtaking as it should be.
Now let’s take a look at what the day tour to the Vinicunca rainbow mountain was like.

The Wake-up Call at 2:30 Am
If you want to be one of the first ones reaching its summit, you have to get up early and leave between 3:00 am and 3:30 am.
You will either meet your group at a meeting point or you will be picked up from your hotel.
Then, you will start heading southeast for around 3 hours, passing beautiful landscapes on not so beautiful roads.
Once you step out of the bus at more than 4,300 m (14,108 ft) you might feel your heart starting to beat a little faster and breathing feels more difficult, especially when you find out that you have a 6 km trail (around 3 hours of hiking) ahead of you.
The hike itself is not too difficult but what makes many travelers suffer is the high altitude and the fact that there is little oxygen in the atmosphere.
The Vinicunca rainbow mountain tour that we at exploor operate ourselves includes the red valley and a shorter hike of only 1.5 hours which is easier.
Some people prefer renting a horse instead of hiking (cost: around $25-30). In case you prefer that option, don’t worry about the scarcity of horses: they are literally waiting for you in the valley just like taxis in the city of Cusco. Crazy!

Having arrived at the top of the Vinicunca, you get to enjoy an unforgettable view that makes up for the eventual pain you have felt during the hike.
However, in case you left Cusco a little later (as most travel agencies do) now the fight for the perfect photo begins.
The most popular photos of the rainbow mountain with no people in the background have become quite difficult to obtain, but you can still get some incredible shots!
Afterwards, you have to hike down again to the parking lot in order to head to a restaurant for a tasty lunch. You will be back in Cusco at around 5:00 pm.
Exploor is one of the few operators that operates small group tours to the Vinicunca rainbow mountain in combination with the red valley, an impressive place that seems out of this world.
Why? Because the entire valley that surrounds you when hiking down is red and looks like a different planet.

So far so good, but after this tour, I asked myself whether there is another trek that allows me to see rainbow mountains without having to hike for various hours.
And yes, there is a very interesting alternative rainbow mountain trek.
The Alternative Tour to the Rainbow Mountain Palccoyo
Now that you know the common Rainbow Mountain trek, imagine an alternative trek, on which you find only 100-200 people crossing your path…per day (!).
A trail, on which you do not get the “classic” rainbow mountain view but instead you can see various mountains with the typical rainbow colors.
And to make it even more special, you get to hike up the trail with the alpaca Pepe or with the llama Jorge accompanying you the entire time until reaching the mountain.

After having gotten up very early for the day trip to Machu Picchu, I was used to it already so leaving at 4:00 in the morning was not problem at all.
Rolando picked me up from my hotel and we immediately had a great connection. The stories he told us in the van about the rainbow mountain and about Peru in general, made me feel like the drive was 30 minutes instead of 3 hours.
Once you get to the starting point, you will already see the first rainbow mountain at the parking lot.

On this trek, you will see a lot of animals joining you during your hike: from alpacas and llamas accompanying you on the ground to condors (when you’re lucky you can spot the vulture gryphus) circling over you.
You can even observe the rarely seen vicuña (part of the wild llama family). But most importantly, you will see fewer people.
This makes you feel like this postcard-like landscape is all yours.

Having arrived at 4900m (16076 ft), we made it to the top. Oh boy, what a view! Just beautiful!
I have to be honest though, hiking at this altitude is no joke. However, it blew my mind that when I checked my watch it said that we hiked only 45 minutes.
Feeling the fresh breeze of the wind in my face while standing on the rainbow mountain and looking at the red valley really made me realize that Peru is more than just Machu Picchu.
Then Rolando woke me up from my daydream and gave us a muña tea with some fresh bread he bought on the road.
That was the right moment to get the camera out and take some shots of the famous mountains, the red valley and the mighty Ausangate Glacier (6375m /20,915 ft high).
We spent around 1.5 hours discovering the surroundingsand Rolando showed us some great spots to take pictures.

The descent will take only around 30 minutes, making the entire hike a lot easier than the common tour.
Afterwards, we visited the local Palccoyo community, a social project that Exploor Peru engages in, and got to know some locals living in the village.
We visited their potato museum, where Laureano explained us more about their history, their work and what their everyday life looks like.
Everyone of us tried on some of their traditional clothes they made themselves and took amazing pictures.
I took home a mini llama for me and a scarf for my mom. It was really interesting to learn about their lifestyle, considering that it’s so different from what most of us are used to.
In exactly these moments you start to appreciate even more what you have and you’re astonished by how these people live their lives.

Leaving the community, we went to a little village close by where we got some delicious lunch from a local lady.
We ate Chicharrón de Pescado (fried fish), Pollo al Wakatay (Wakatay chicken), yellow rice and salads; everything was really tasty.
After the well-deserved lunch we started heading back to Cusco, where we arrived a little before 5:00 pm.
I was a little tired because I felt the effects of the altitude but that was nothing compared to what most people felt after having hiked the Vinicunca trek for 5-6 hours.
I have to say that the alternative tour to the rainbow mountains was definitely one of the best tours I have done in Peru.
It has a reasonable price, a local guide that really knows what he is talking about and the highlight of the tour, the rainbow mountains, are 100% worth seeing.
Apart from that, the typical Andean lunch was really good.
Still, after having seen many people complain about problems with the altitude in general I think it is super important that you are aware of this and prepare yourself well, just like I did.
Preparation and Acclimatisation Is Everything
No matter which tour you end up doing, you should always remember that the conditions are -most likely- very different to the places you have visited before so that your body needs some time to acclimatize.
I followed the tips on how to avoid the altitude sickness and didn’t have any problems with the altitude.
I’d still recommend bringing extra oxygen (can be bought at every pharmacy in Cusco), Soroche pills and some coca leaves you can chew in case you feel sick.
Even if you are an athlete, the local conditions should be taken seriously and I highly recommend you to get acclimatized for 1-2 days in Cusco before doing the rainbow mountain-or any other high altitude trekking tour.
I mean we are talking about around 5000m here…

I don’t want to scare you off, I just want to make sure you prepare yourself properly so you don’t experience any unpleasant surprises.
In terms of physical preparation, I’d suggest you start exercising before your trip to Peru (especially if you want to do various trekking tours). Still, a good physical shape is no guarantee of avoiding altitude-related problems (headache, nausea etc.).
And don’t get me wrong, with this post I don’t want to convince you that the Vinicunca trek is bad and the alternative tour to the rainbow mountains is the only option, certainly not.
What I want to do is present you an option that is a lot easier and that helps you avoid the pain points many travelers have faced before you.
On the one hand, the Vinicunca trek is already starting to become conquered by hundreds of travelers every day, requires more hiking and will physically exhaust you more.However, the tours offered are normally quite cheap.
On the other hand, the alternative tour is less exhausting and still allows you to feel like an explorer that is discovering something new, without any crowds around.
In the table below, you can see a final comparison of the two tours we operate ourselves.
| Category | Vinicunca | Palccoyo |
|---|---|---|
| Trekking distance | 1.5 – 2 hours until reaching the top (return through Red Valley takes 2.5 – 3 hours) | 45 mins – 1 hour until reaching the top |
| Extra | – Hike through red valley | –Visit local community -Visit Inca bridge – Hike with a llama/alpaca – Visit rock formations on top |
| With Exploor | One of the first ones on top | One of the first ones on top |
| Number of Rainbow Mountains | 1 | 3 |
| Number of tourists p. day | 1000 – 2000 | 50 – 100 |
| Horse renting | Yes, but not until the top (costs around S/ 80) | No |
| Food | Breakfast & lunch | Breakfast & lunch |
| Entrance costs | S/ 10 ($3) and S/ 10 ($3) for Red Valley | S/ 10 ($3) |

Frequently Asked Questions About Visiting Rainbow Mountain Peru
Is Vinicunca or Palcoyo the better route to Rainbow Mountain?
Vinicunca is the better choice if you want a challenging hike and the classic postcard view of Rainbow Mountain. The trail is steeper, the altitude is higher, and the total hiking distance is longer, so it suits travelers who are in good shape and already acclimated in Cusco for at least two or three days. Palcoyo is better for an easier experience, since the trail is shorter, the slope is gentler, and you see several colorful mountains from different viewpoints. If you are short on time, traveling with kids, or worried about altitude, Palcoyo is usually the smarter option.
How long does it take to visit Rainbow Mountain from Cusco?
A typical day trip from Cusco to either Vinicunca or Palcoyo takes about 10 to 12 hours in total. Most tours start with a hotel pickup between 3:00 and 5:00 a.m., followed by a drive of about 3 hours to the trailhead. The hike itself usually takes between 2 and 4 hours, depending on the route, your pace, and weather conditions. After time at the viewpoints and a meal stop, you return to Cusco in the late afternoon or early evening. The actual hiking time is only a small part of the full-day experience, since the drive from Cusco is long.
How difficult is the Rainbow Mountain hike and what altitude should I expect?
The main challenge of Rainbow Mountain is the altitude, not the distance. On the Vinicunca route, the trailhead sits at about 4,300 meters above sea level and the viewpoint reaches around 5,000 meters. The hike is around 6 to 7 kilometers round trip, with some steep sections near the top. On the Palcoyo route, the hike is shorter and the slope is milder, with viewpoints slightly lower than Vinicunca. Even so, you still walk above 4,500 meters. Most healthy travelers can complete at least one of the routes, but you should spend a few days in Cusco to acclimate and walk at a slow, steady pace.
When is the best time of year and day to visit Rainbow Mountain?
The best time of year to visit Rainbow Mountain is during the dry season from May to September. During these months, you have a higher chance of clear skies, more stable trails, and stronger color contrast on the mountain. The rainy season, from November to March, often brings clouds, snow, or mud, which can cover the colors and make the hike harder. The best time of day to visit is in the early morning. Most tours aim to reach the viewpoint before late morning, which helps you avoid strong sun, afternoon storms, and the largest crowds.
Is it necessary to book a guided tour from Cusco to Rainbow Mountain?
Most travelers book a guided tour from Cusco, since public transport to the trailheads is limited and connections can be confusing. A guided tour typically includes hotel pickup and drop-off, round-trip transport, a local guide, entrance fees, and breakfast and lunch. Guides help you manage the pace of the hike, watch for signs of altitude sickness, and give information about local communities and the geology of the mountains. Private tours cost more but offer flexible timing and a more personal experience. Independent travel is possible but involves arranging private transport and managing permits and safety on your own.
