Road to the Junín Lakes: Driving to Alcacocha, Tarusmachay, and Oshgomachay

Get ready for an epic Andean adventure! Deep in the heart of Peru's Central Andes, near Junín, lies a mind-blowing route that winds past three ridiculously gorgeous glacial lakes: Alcacocha, Tarusmachay, and Oshgomachay. This isn't your average Sunday drive; it's a high-altitude test of you and your vehicle through the stark beauty of the Meseta de Bombón.

Forget smooth pavement – this is a classic "trocha," a white gravel track carving through a vast, treeless plateau. Imagine endless ichu grass swaying in the fierce Andean winds, with distant peaks as your only companions. It’s raw, exposed, and unbelievably scenic.

Starting just north of Junín, you peel off the civilized 3N Road and onto this 14.9 km stretch of pure adventure. Don’t let the average gradient of 2.85% fool you; the real challenge is the altitude. You’ll be climbing a cumulative 426 meters in seriously thin air!

The route flows organically through the mountains. First, you'll hit Laguna Alcacocha (at a dizzying 4,366m). Then, it's upwards to the highest point by Laguna Tarusmachay (4,443m), before leveling out a bit near Laguna Oshgomachay (4,430m). The whole drive is a slow, steady climb where you'll definitely feel your engine straining above 4,000 meters.

Expect mostly loose gravel and compacted earth under your tires. In dry weather, it's dusty but manageable. But remember, this is extreme high-altitude driving! Oxygen is scarce, and you'll likely feel the effects of altitude sickness if you haven't acclimatized in Junín or nearby towns.

Safety first, especially during the rainy season (November to April). Snowfall and landslides can make things seriously dicey. There are absolutely no services, no gas stations, and hardly any other vehicles out here. A 4x4 with good tires is essential, as the gravel gets slick when wet, and those steep sections demand traction.

Before you ditch the 3N highway, give your ride a thorough check-up. Thin air makes engines work overtime, so check those tires and cooling system! That "lack of oxygen" also affects your reflexes and judgment. If you get a headache or feel dizzy, stop or head down immediately. This route is your ticket to the authentic Peruvian puna, far from the tourist throngs, where your only company might be alpaca herds and the serene, frigid lagoons.
