El Impenetrable: our first time, a memory for life
Travel log from Centinela Explora's first expedition to El Impenetrable National Park (Chaco, Argentina): wild nature, authentic encounters, birdwatching and a very special birthday celebration under the stars of the Bermejo River.
Our first experience in El Impenetrable
September 2024 | Chaco, Argentina
In September 2024, we took the very first step of what would later become Centinela Explora. And we couldn't have chosen a more meaningful place: El Impenetrable National Park, a remote and untamed corner of northern Argentina where nature still rules and every trail feels like it's being walked for the first time.
There were six of us, but it felt like family. Three women, three men — including Salva, a young boy with a big heart, who joined us for days that will stay in our memory forever.

Wildlife and meaningful moments
Over five days, we explored the Chaco forest, hiked its trails under the sun and the full moon, sailed the Bermejo River and visited a local community that welcomed us with open arms.
One of the most emotional moments was spotting a Plush-crested Jay (Cyanocorax chrysops). It’s not a rare bird, but its intense gaze and striking blue plumage against the dry forest backdrop made it unforgettable.
A birthday to remember
On day three, deep in the heart of the park, Salva turned 12. It was his first birthday in the wild. We sang under the open sky, with the Bermejo breeze and plenty of hugs. There was cake, candles, and above all, a moment he will never forget.

What we took with us
Beyond the trails, the wildlife, and the river, this trip gave us something greater: connection. With the land, with each other, and with ourselves.
“A truly beautiful and enriching experience. The biodiversity and the warmth of the local community left a deep mark on me.”
