Driving the rough RP119 to Laguna Margarita in Tierra del Fuego
Ruta Provincial 119 (RP119) is a challenging unpaved track located in the Tierra del Fuego Province, at the southern tip of Argentina. Stretching for 18 km through dense sub-antarctic forests, this road is the primary access point for those looking to reach the remote shores of Lago Escondido, Lago Fagnano, and finally, Laguna Margarita.

How difficult is the drive on Ruta Provincial 119?
The journey on the RP119 begins at a junction with the legendary Ruta 3. From the moment you leave the main highway, the surface turns into a mix of rough gravel and unpredictable mud. The track is extremely narrow, often barely wide enough for a single vehicle, with vegetation constantly encroaching from the sides. The 18 km trip is a slow crawl where the driver must navigate deep ruts and sections of standing water. After heavy rains, the road frequently becomes impassable even for prepared vehicles, as the soil turns into a thick, bottomless peat that kills traction instantly.
What are the hazards of the lakes route in Tierra del Fuego?
The primary hazard on the RP119 is the lack of space and the unstable ground. There are no safety barriers, and the margins of the road are often soft and prone to collapsing under the weight of a heavy 4x4. The dense forest canopy keeps the road surface damp year-round, meaning that patches of slippery mud can appear even during the drier months. Visibility is also limited by the tight turns and the thick trees, making encounters with oncoming local traffic or fallen logs a constant risk. In this part of the world, a mechanical failure or getting stuck means being isolated in a cold, windswept environment far from any immediate assistance.
Is a 4x4 mandatory to reach Laguna Margarita?
Attempting the RP119 in a standard passenger car is a guaranteed way to damage the undercarriage. A high-clearance 4x4 is mandatory to clear the rock outcrops and deep grooves carved by the local rain runoff. Proper all-terrain tires are essential to maintain grip on the loose stones and muddy climbs. Before starting the drive towards Laguna Margarita, check your recovery gear and ensure your winch or tow straps are accessible. This is a journey through the "raw" side of Tierra del Fuego, where mechanical resilience and careful wheel placement are the only ways to reach the final destination without calling for a rescue.
Why drive the RP119 despite the risks?
The logistical difficulty of the RP119 is the price to pay for accessing some of the most pristine glacial lakes in the southern hemisphere. While most travelers stay on the paved sections of Ruta 3, the RP119 takes you deep into the heart of the Fuegian landscape. Reaching Lago Escondido or the final point at Laguna Margarita provides a sense of solitude that is impossible to find on the more commercial routes. It is a technical drive for those who value the challenge of the terrain as much as the beauty of the destination, requiring a focused mind and a well-maintained vehicle to conquer the last frontier of Argentina.
