De Sacs et d'Eau

One day, we decided to leave. Everything else gets written here, and on the road!

Welcome to De Sacs et d'Eau

We're Tristan and Mathilde. A French duo who set off for a year of backpacking across South America, with one simple belief: the best memories are built along the way.

De Sacs et d'Eau is our travel blog. Complete guides, itineraries tested on the ground, and interactive maps to help you plan your trip with everything you need, straight from your pocket.

To do that, we favour overland travel over flying, buy local, and choose accommodation and businesses run by locals. Travelling far, yes - but staying mindful of our impact.

Currently, we are

in Mexico

Since we set off, we've mostly been crossing the world by bus, boat, train and on foot. Not out of necessity, but by choice. We want to cover every kilometre to discover this planet we love without slowly wearing it down - travelling without planes means admiring more scenery, supporting local businesses, meeting more people, and putting a little less carbon into the atmosphere. We only fly when there's truly no alternative, never out of convenience.

25+ countries crossed | 50,000+ km overland | Flights kept to a strict minimum | 70+ guides published

Follow this adventure day by day through our stories: local traditions, night-bus mishaps, market kitchens, and landscapes that change everything.

Our stories from this journey

Travelling also means collecting memories that stay with you. We've learned from local guides, been stunned by a breathtaking landscape, and discovered cultures we knew nothing about. We share our adventures, our favourite moments and our discoveries to inspire your next departure.

San Rafael, a natural next stop after Mendoza

Mendoza: three days to discover the city

After Córdoba, Mendoza was supposed to be a simple stopover. Two days in a transit town, then three full days before hitting the road again. Nothing more. We arrived with that plan in mind, without imagining that Mendoza would completely change how we spend our time. | Our travel guide, specially crafted by De Sacs et d’Eau
