Can you imagine a place where enormous stone columns defy gravity and, just minutes away, a waterfall crashes forcefully amidst landscapes that seem from another planet? That and much more is what the Pillones Waterfalls and the Imata Stone Forest offer, two natural treasures located in the Arequipa region. They are destinations that honestly surprised me the first time I visited: the sound of water, the cold wind of the puna, and those rocky silhouettes that look like sleeping giants. If you’re looking for an authentic experience in nature, this complex is perfect for disconnecting and feeling tiny in the vastness of the high plateau.
The intention behind this guide is to tell you, in detail and based on real experiences, what you can expect when visiting these places. From how to get there, to what to bring and how much it costs, here I share everything essential to make your adventure to Pillones and Imata unforgettable. If you’ve ever been curious about those little-explored sites in Arequipa or just want a different getaway, keep reading because this destination has much more than you imagine.
Description of the Pillones-Imata complex
The natural set formed by the Pillones Waterfalls and the Imata Stone Forest is one of the best-kept secrets of southern Peru. Located over 4,000 meters above sea level, this complex combines the power of water and the majesty of geological formations that seem sculpted by ancient artists. What catches my attention the most is how, in just a few kilometers, you can go from a high Andean tundra landscape to a rocky maze worthy of fantastic tales.
I’ve noticed that many travelers only know one of the attractions, but the experience is truly enhanced by exploring both. While Pillones mesmerizes with its waterfall and the enveloping sound of water, Imata surprises with its columns and whimsical figures carved by centuries of wind and rain. Here, there are no crowds or street vendors; just pure nature, wildlife, and that unique feeling of being far from everything.
Geographical location
The complex is located in the Caylloma province, within the Arequipa department. To quickly locate it on your mental map, it is situated northeast of the city of Arequipa, right in the southern Andean high plateau. Both Pillones and Imata are part of the extensive high Andean ecosystem, characterized by open pampas and immense skies.
The Arequipa-Puno road (PE-34A) is the main route that crosses this area. The Stone Forest is about 150 km from Arequipa city, while the Pillones Waterfalls are located about 8 km before, taking a marked detour. In my experience, the journey is as impactful as the destination: you’ll see turquoise lagoons, herds of alpacas, and snow-capped peaks in the distance.
How to get there from Arequipa
Getting to Pillones and Imata is an adventure in itself. Most people opt for a private vehicle or organized tours; public transport doesn’t reach the attractions directly, though it can drop you off relatively close.
- By private car: Depart from Arequipa on the road to Puno (PE-34A). After passing the town of Imata (where buses usually stop), look for the marked detour to the Pillones waterfalls on your left.
- By tour: Local agencies offer complete excursions that include round-trip transportation, a guide, and stops at both attractions.
- By interprovincial bus: You can take a bus on the Arequipa-Puno route and get off in Imata (you need to inform the driver). From there, you’ll have to walk or hire local transport.
The trip takes between 3 and 4 hours depending on traffic and weather. Personally, I recommend leaving very early (around 5 a.m.) to make the most of the day and avoid the intense cold of the evening.
Location map and routes
| Point | Distance from Arequipa |
|---|---|
| Pillones Waterfalls | Approximately 142 km |
| Imata Stone Forest | Approximately 150 km |
From the main road, there is basic signage, though not always very visible; that’s why it’s useful to carry offline maps or ask local drivers if you have doubts. The route is mostly paved but has sharp curves and slippery sections during the rainy season.
Imata Stone Forest: rock formations
The Stone Forest is, without exaggeration, a landscape from another world. It is an impressive set of volcanic rocks eroded over thousands of years by wind, rain, and the extreme temperature changes typical of the high plateau. The shapes are so whimsical that some visitors give them names: “the turtle,” “the camel,” “the soldier.”
In my opinion, the most fascinating part is wandering aimlessly among the columns and letting your imagination run wild: each angle reveals new silhouettes. The environment is silent except for the wind; it’s ideal for photography, meditation, or simply admiring how nature creates art without human help.
- Volcanic rocks with varying heights (some exceed 10 meters)
- Natural paths among the formations
- Improvised viewpoints for spectacular panoramas
- Little human presence: ideal for those seeking tranquility
Pillones Waterfalls: characteristics and height
Pillones is a powerful waterfall formed by the river of the same name that winds between enormous rounded boulders. The main drop is approximately 10 meters high, enough to create a refreshing mist on sunny days (though believe me, the cold never fully goes away).
Unlike other more accessible waterfalls, reaching Pillones involves descending a rocky path for about 15-20 minutes from where you leave the vehicle. The effort is worth it: you’ll see how the water hits the rocks, creating crystal-clear pools surrounded by vegetation resistant to extreme cold.
- Approximate drop: 10 meters
- Variable width depending on the season (more flow during rains)
- Access via natural stairs and simple walkways
- Not suitable for swimming due to the intense cold of the water
Flora of the high Andean zone
The vegetation here is a perfect example of adaptation to the harsh climate. Hardy grasslands, ichu (Stipa ichu), and small drought-resistant creeping plants dominate. It’s common to find wetlands near the river where mosses and lichens as ancient as the stones themselves grow.
- Ichu: Golden grass typical of the high plateau, a food base for camelids
- Tola: Low shrub that serves as a refuge for small birds
- Lichens: Proliferate on moist rocks near the water
Don’t expect large trees or dense forests; here, plant life is discreet but vital for the ecosystem. In my experience, walking among golden ichu under the intense sun is something you won’t easily forget.
Fauna: vicuñas, alpacas, and birds
Once, I encountered a herd of vicuñas grazing peacefully just a few meters from the trail: it was one of those magical moments that only the Peruvian puna offers. Additionally, it’s common to spot alpacas (many belong to local communities) and sheep scattered across the fields.
Among the birds, caranchos (milans), hawks, and some endemic species like the Andean partridge stand out. As far as I understand, some have seen vizcachas jumping among the rocks at sunset; though I haven’t had that luck yet.
- Vicuñas: Protected Andean mammal, national symbol of Peru
- Alpacas: Domesticated, local economic base
- High Andean birds: Caranchos, Andean gulls, Andean partridges
Entrance fees and services
Unlike other mass tourist destinations, the costs here are quite accessible. According to my last visit:
- Pillones Waterfalls: S/ 5 per person (updated local rate)

| Service | Availability |
|---|---|
| Basic sanitation (public restrooms) | Only at main entrances |

There are no nearby restaurants or immediate accommodation; it’s advisable to bring light snacks and enough water. Some communities sell hot drinks or fresh cheese at stops near the main road.
Weather and meteorological conditions
I’m not exaggerating when I say that the weather here can change radically in a matter of minutes. Temperatures typically range from -5 °C at dawn to highs close to 15 °C during the day if it’s sunny. The wind is constant and can be biting, especially outside of the southern summer.
- Sunny but cold days even in summer
- Frequent morning fog between May and August
- Moderate rains between December and March (caution with slippery roads)
- Extremely cold nights year-round
In my personal experience, I always bring extra clothing even if I think I won’t need it. Better safe than sorry; a warm hat can be your best friend up here.
Recommended equipment for the visit
Don’t underestimate the altitude or the weather; being well-prepared makes the difference between a memorable adventure or suffering from cold or fatigue. The basics to enjoy without setbacks:
- Thermal jacket: Waterproof windbreaker
- Trekking shoes: Non-slip soles for rocky paths
- Sunglasses/hat: Essential sun protection at over 4,000 meters above sea level
- Optional trekking pole: Eases descents to Pillones waterfall
- Small backpack: Water (at least one liter per person), energy snacks, camera
