Where does Ruta 3 Tierra del Fuego start and end?

Get ready for the ultimate road trip on Ruta 3 in Tierra del Fuego! This epic 395km (245-mile) stretch is supposedly the southernmost paved road on the planet, winding its way through the breathtaking Tierra del Fuego Province of Argentina.

Your adventure kicks off at Cabo Espíritu Santo, right on the Chilean border, and cruises all the way to Ushuaia, that cool little town they call the "End of the World." But wait, there's more! The road keeps going into Tierra del Fuego National Park, wrapping up at Bahía Lapataia where you'll find a sign marking the very end of the line.

Now, let's talk road conditions. The path through the national park starts a bit rough and narrow, but don't worry, it gets better, turning into a fully paved road. Heads up, though—some spots can be a little rough around the edges due to maintenance issues, and you'll likely share the road with big trucks and heavy machinery.

For a smooth ride, keep that gas tank full—especially in remote areas where gas stations might be MIA. You'll hit some police checkpoints at the border, so have your documents handy. Plan plenty of pit stops to soak it all in and book your stays ahead of time, especially during the busy summer months.

You can drive Ruta 3 year-round, as they keep the snow cleared. That said, try to avoid April through September when the weather can get gnarly and closures are more common. Keep an eye on the weather forecast and watch out for those Patagonian winds—passing trucks can be your best friend as temporary wind shields.
