Ruta Nacional 23 – Magallanes Patagonia Steppe
Patagonian highway through endless guanaco steppes
Ruta Nacional 23 cuts a straight gravel line across 200 miles of Patagonian emptiness between the Argentine border and Punta Arenas, passing through estancias where guanacos outnumber people 100 to 1. This is the loneliest highway in Chile, crossing windswept grasslands broken only by distant mountain ranges and the occasional gaucho on horseback. The road surface alternates between decent gravel and bone-jarring washboard, with fuel stops separated by massive distances and the constant Patagonian wind trying to blow you sideways.
Easy to moderate difficulty depending on recent maintenance – stock high-clearance vehicles handle it fine in good conditions, but 4WD helps in wet weather when the clay turns to soup. Fuel up at every opportunity and carry spares for the inevitable tire damage from sharp gravel. Best traveled October through March when daylight stretches long and temperatures stay above freezing. Wild camping is legal anywhere off the road. You’ll cover serious distance with nothing but endless sky, wild horses, and the kind of solitude that makes you question why you ever lived in a city.

Frequently asked questions
Can a stock Hilux or 4Runner run RN-23 without any mods?
Yes. The route is gravel highway the whole way — stock high-clearance is genuinely all you need. A 2WD with decent ground clearance could do it in dry conditions, but AWD or 4WD is smarter given the wind and occasional wet sections.
What's the weather like and when should I avoid this route?
April through September brings brutal Patagonian winds, freezing temps, and reduced daylight. October through March is the window — expect wind regardless, but temperatures are survivable and the steppe is at its best.
Are there border crossings or permits required along RN-23?
The route crosses between Chile and Argentina at multiple points depending on your line, so have your vehicle paperwork, passport, and TVIP (temporary vehicle import permit) sorted before you go. No trail-specific permits required — it's a public national highway managed by the Ministerio de Obras Públicas.
What's the hardest part of this route?
Nothing technical — this isn't a trail that'll test your lockers. The real challenge is the wind, which can push vehicles at highway speed and turns gravel into a sandblaster. Gusts of 100+ km/h are common; slow down and respect it.
How far apart are fuel stops, and is there cell service out there?
Plan for gaps of 150–200 km between reliable fuel — carry a serious spare supply. There is no cell service across the steppe; a satellite communicator is not optional on a 323 km route this remote.
