Explore the hidden corners of Mendoza and live unique experiences.
Exploring Mendoza is like opening a box of surprises. Sometimes it feels like weโve already seen it all, but there are still hidden corners waiting to be discovered. In Mendoza, youโll always find its most famous attractions: the countryโs top wineries, mountain treks through the Andes, and thrilling adventure experiences. But thatโs not all โ the best part is that Mendoza always has something more to reveal.
If you dare to go beyond Mendozaโs classics, youโll find a lagoon surrounded by mountains, a salt flat near San Rafael, and even a reserve with inactive volcanoes. Argentina is vast and beautiful, and Mendoza is one of those provinces with a lesser-known โB side.โ
At Rentennials we want you to explore Mendoza and Argentina your own way โ discovering new places and reaching the hidden gems each destination has for you.

Salinas El Diamante from San Rafael

What are the Salinas del Diamante?

Nowadays, it has become a tourist destination where visitors can learn about the salt production process up close.

What youโll find in Telteca Forest Nature Reserve
The Telteca Forest Nature Reserve is a biodiversity haven in northeastern Mendoza. It offers a glimpse into how this region looked centuries ago. The main vegetation includes centuries-old carob trees, jarillas, chaรฑares, and cacti.

Local Huarpe communities still live nearby, preserving their traditions and deep connection with the land โ making this reserve essential to Mendozaโs cultural heritage.
Things to do in Telteca Forest

My favorite: a secret spot in Vallecitos โ dining by the Rรญo Blanco
Iโm almost hesitant to share this placeโฆ not because itโs not worth it (quite the opposite!), but because its magic lies in the fact that very few people know about it โ and even fewer go there.
But if thereโs one plan I repeat every year without fail, itโs this: having lunch by the Rรญo Blanco in Vallecitos.
The drive to Vallecitos is already an experience โ a gravel road surrounded by mountains that any vehicle can manage (as long as you donโt go up to the old ski resort). Just keep in mind that the altitude can affect some people and, in winter, snow chains may be essential.
During the week, itโs almost deserted. Youโll find peaceful spots to set up your folding table, chairs, and enjoy the sound of the river, the fresh air, and a sunny picnic.
On weekends or holidays, itโs a different story โ expect crowds and limited parking.
Thatโs where my best-kept secret comes in: a hidden place where you can truly disconnect from the world and connect 100% with nature. Perfect if youโre looking for solitude, reflection, or simply a moment of pure peace.
The Rรญo Blanco isnโt just any river โ itโs glacier meltwater that supplies much of Mendoza Province. Itโs said to be one of the purest waters in Argentina โ and if you visit respectfully, youโll feel it.
๐ซ IMPORTANT: As in most of Mendoza, lighting fires is prohibited. But if you decide to anyway (since many still do), please be extremely careful. Extinguish it completely with plenty of water and leave no trash behind. This place is magical because itโs cared for โ help keep it that way.
Hereโs the exact map location ๐
Thereโs grass and smooth rocks to sit on โ enjoy it and tell us how it went! Oh, and if youโre going here, you definitely need to rent a car with Rentennials โ these are the kinds of experiences you donโt share with just anyone. ๐
