The trail: what to expect
The trail starts at Ruta 3, about 20 km east of Ushuaia. Total length — 9–10 km round trip, elevation gain ~200 m. The first 3 km — gentle forest through the subantarctic beech forest (lenga). Then the trail comes out onto an open peat bog — this can be wet, so waterproof footwear is mandatory.
After the boggy section, the gradual climb begins. Early in the season (October–November) snow may still be on the upper sections — trekking poles will help. At the height of summer (December–February) the trail is fully open.
The last kilometer before the lake is the steepest. Under your feet there may be slippery clay after rain. A good rest stop — the exit from the forest onto an open plateau, where the view of the mountains and valley first opens up.
Finale — arrival at the lake. The turquoise color of the water is explained by glacial flour — the tiniest particles of rock that the glacier grinds as it moves.
Time on the trail
Approximate: 2–2.5 hours up, 1.5–2 hours down. Total 4–5 hours with stops. Pace depends most on the group's fitness and the condition of the trail (slower after rain).
When to go
Main season — November–April. July–September the trail is under snow, inaccessible to most tourists. The best month — January or February: dry trail, long daylight, best light for photos — morning (before noon) when the sun lights up the lagoon.
What to bring
- Footwear: trekking boots or sneakers with grip. Loafers and leather shoes — no.
- Water: minimum 1.5 liters per person.
- Clothing: several layers. Morning may be cold, by midday warm, by evening cold again.
- Trekking poles: recommended, especially for the descent.
The most common mistake is showing up in regular sneakers without grip. On the boggy section you'll get wet, on the climb you'll slip.
Start: parking and entrance
At the trailhead there's a small parking lot (20–30 cars). Entry is free, no paid tickets. A small café by the road works 9:00–17:00 — hot drinks, pastries.
Frequently asked questions
Is special preparation needed? Average fitness is enough. If you walk regularly, you'll manage.
Can I go alone without a guide? The trail is marked, hard to get lost. But weather in Patagonia changes fast — a guide gives a safety margin and knows the best photo spots.
Suitable for kids? Yes, kids from 8–10 usually manage. For younger ones the route may be too long and boggy.
What to do if bad weather starts? Turn back. Thunderstorms in mountain terrain are dangerous. That's one of the reasons it's worth going with a guide.
How much does the excursion cost? Guide for the trek — from $200 per group of up to 3.
