Laguna Esmeralda Hike, Ushuaia: Trailhead, Mud, Winter Snowshoeing and Guided vs DIY

What makes the hike harder than the numbers

• The difficulty is the mud, not the climb. The gradient is gentle for 4 km and steepens only in the last few hundred meters. People get slow, sore and occasionally rescued in the peat bog (turbal), which stays saturated all year. TripAdvisor reviews from March and April 2026 complain about “four hours round trip through the mud” and a return “more challenging, because there was a lot of mud, risk of falls.”
• Boardwalks help, but long muddy stretches remain. A first stage of railed boardwalk opened in March 2022, funded by the national Programa Nacional de Infraestructura Turística and INFUETUR. At the opening, Vice-Governor Mónica Urquiza described “aproximadamente 500 metros de pasarelas dispuestas en estos dos tramos.” On 12 January 2026 INFUETUR president Dante Querciali told Sur54: “En Laguna Esmeralda están en proceso 370 metros… En total, realizamos 850 metros de pasarelas y planchados en las zonas más críticas.” El Diario del Fin del Mundo’s 20 January 2026 report on INFUETUR’s results gave a slightly different figure: “mejoras en el sendero a Laguna Esmeralda, con casi 800 metros de pasarelas.” Read these as cumulative totals, not 800 m of new decking.
• It is busy. INFUETUR has called it the most-visited trail in the province, and officials at the March 2022 boardwalk opening said, as reported by Patagonia Andina: “En esta temporada de verano lo recorrieron aproximadamente mil personas por día.” Start by 8:30–9:00 for quieter trails and better light.
• Rescues happen, even on an “easy” trail. La Nación, citing Comisión de Auxilio Ushuaia data in June 2026, reported that rescue operations across all Ushuaia trails went “de 51 operativos en la temporada 2020/2021 a un pico de 93 en 2023/2024… 75 en 2024/2025 y 78 en 2025/2026,” with getting lost the leading cause. On Laguna Esmeralda itself, a gendarmerie mountain unit stretchered out an injured 35-year-old hiker on 1 January 2026, and Cristian Álvarez, Ushuaia’s municipal Civil Defense director, told La Nación: “En un caso ocurrido en la zona de Laguna Esmeralda participaron alrededor de 18 rescatistas para evacuar a una turista lesionada.”

With the right boots it is a superb half day. In sneakers it is miserable and risky, so it is not the “easy stroll” many listings promise.

Where is the Laguna Esmeralda trailhead?

The trailhead is a large, free gravel car park on the left side of Ruta Nacional 3, about 18 km northeast of central Ushuaia (20–30 minutes’ drive), a few hundred meters before the entrance to the Valle de Lobos winter center.

Look for the “Laguna Esmeralda” sign and information board at the edge of the forest. The official board repeats the cut-off times and warns that conditions between April and September can become dangerous because of ice, snow and short days.

Don’t pay at the wrong gate. You pay nothing if you start from the roadside car park. Some tours, especially in winter, start instead from private centers in the Tierra Mayor valley, such as Refugio Nunatak/Husky Park. That access is part of the tour package; it is a different approach, not a mandatory fee.

A fee could come later. In 2025 the province received private-initiative proposals for a “Nodo de servicios Laguna Esmeralda” (a 30-year concession including trail maintenance and ticketed access) and for a visitor center, parking, toilets and a footbridge over RN3. These are proposals under analysis, not approved works. We will update this page if anything is approved.

How long is the Laguna Esmeralda hike, and how hard is it?

It is 9 km return and moderate. The climbing is modest (about 220–260 m), but slippery roots, deep peat mud and a short rocky final ascent make it slower and more tiring than 9 km and 220 m sound.

AllTrails users sum it up as “There is mud, mud and more mud!” and one recording notes “very muddy and slippery.” The provincial tourism body describes the terrain as wet and slippery and says boots, waterproofs, poles and warm layers are needed all year.

Kids: many operators accept ages 9–10 and up. It does not suit anyone with knee or mobility problems on a wet day.

Laguna Esmeralda route, section by section

Distances and times are approximate (our estimate from GPS tracks and operator descriptions) at an average pace. Allow more in mud or snow.

1. 0 km: car park and trail board (0:00). Read the cut-off times, check the sky to the west and switch your phone’s offline map on.
2. 0–1.5 km: lenga forest (0:00–0:35). A clear, marked path climbs gently through regenerating southern-beech (lenga) forest past old woodcutters’ stumps. Roots get slick when wet.
3. About 1.5–2.5 km: first peat bog and boardwalks (0:35–1:05). The valley opens with views of Cerro Bonete, the Sierra Alvear and the Tierra Mayor and Carbajal valleys. Railed boardwalks cover the worst sections; off them, the turbal is a sponge. Stay on the boardwalk or the main line, because the peat is fragile and slow to recover.
4. About 2.5–3.3 km: second forest band and beaver dams (1:05–1:30). Abandoned beaver dams (castoreras) show the damage done by North American beavers introduced in 1946. Logs and planks help over the wettest patches.
5. About 3.3–4.2 km: Río Esmeralda peat flats (1:30–1:55). The muddiest part. The path follows the glacial stream across open bog with small stream crossings. In October and after rain it is ankle- to shin-deep in places.
6. About 4.2–4.5 km: final climb to the lake (1:55–2:10). A short, steeper, rockier pull over the moraine lip. Then the lake appears, green-turquoise from glacial sediment off the Ojo del Albino.
7. At the lake (30–45 min). Walk a few meters around the shore, or cross near the outflow and climb slightly for the classic elevated shot. Eat and add layers, since it is always colder and windier here, then head back the same way (about 1:45–2 h).

Can I continue to the Ojo del Albino glacier?

Only with a licensed mountain guide. INFUETUR states that walkers without climbing experience and technical gear “NO DEBEN REALIZAR ESTE ASCENSO” because of ice, rockfall and slow rescue access.

• What it involves: from the lake, an extra 5 km or so each way up the main tributary, through fallen trees and old beaver workings, then a large unstable scree slope and a steep final section to the glacier and its lagoon at roughly 900 m. The whole day is about 18–21 km, about 800 m of gain and 8–10 hours.
• Operators: guided Ojo del Albino treks run from about ARS 220,000 (Happy Guest). Some operators limit it to ages 18–55 and require stiff waterproof high-ankle boots, and guides carry ropes for the hardest section.
• Why the warning is serious: in March 2026 US hiker Sean Christopher Bartel, 37, went missing after setting out on the Esmeralda trail. Police found his rental car at the trailhead and his body more than 3 km beyond the parking area, past the lake toward Ojo del Albino. Martín Bobba, head of Ushuaia’s Comisaría Primera, told Infobae on 18 March 2026: “Habría caído de unos 90 metros de altura por las primeras pesquisas en el lugar.” La Nación reported he had set out without adequate equipment. Earlier deaths on the same circuit include a British hiker in 2018 and an Argentine hiker with hypothermia in 2021.
• Refugio: there is no staffed refuge on the route. AllTrails users mention informal wild-camping spots near the lake and higher up; check current rules before planning a night out.

How to get to Laguna Esmeralda (cómo llegar) in 2026

There is no regular city bus to the trailhead. Your options are a shared minibus, taxi, Uber, rental car or a tour.

The return leg is the weak link. Uber pickups at the trailhead are unreliable and phone signal is partial. Book a combi with a return slot, or agree a time with a taxi or remis driver before you set off. Taxis sometimes wait in the car park in high season, but don’t count on it in October.

Hitchhiking: locals and backpackers do thumb rides along RN3, but traffic thins in the afternoon and in the shoulder season. Don’t make it your only plan.

Guided vs DIY: which should you choose?

Go on your own in summer if you are an experienced hiker with proper boots. Book a guide in winter and the shoulder months, if you are traveling solo without hiking experience, or if you want the Ojo del Albino.

Representative 2026 guided prices (per adult):

Our pick on GetYourGuide: the Emerald Lagoon Trekking Tour at $99, rated 4.9/5 from 358 reviews, is a 6-hour day with hotel pickup, a local trekking guide, a box lunch and a hot drink. The operator lists the walk at about 10 km return and 4–5 hours, with about 200 m of gain. On Viator, the Emerald Lagoon Trekking from Ushuaia, Small Group costs from $95, rated 4.7/5 from 92 reviews. Pick the GetYourGuide day for its far larger review record, or the Viator one if you want to save a few dollars.

Trek plus a mountain-dome meal: the “Confort” style trek ends with a hot meal in a heated dome, with lamb stew (cazuela de cordero) on the menu. On GetYourGuide this is the Esmeralda Lagoon Trekking Tour with Lunch at a Mountain Dome, from $163 and rated 5.0/5, but from only 3 reviews so far, so read them before you book. Antartur’s Husky Park packages in the Tierra Mayor valley add a summer husky walk with lunch (cordero a la criolla) or winter snowmobile, sled and snowshoe days. Private “Esmeralda plus Fuegian valleys” tours on GetYourGuide and Viator run from about US$108–120.

Group sizes vary; some winter products cap groups at 15.

Laguna Esmeralda in winter: snowshoeing and the frozen lake

From June to September the valley is under snow and the lake usually freezes. It is spectacular, but the path disappears under snow, so go with a licensed guide and crampons or snowshoes (raquetas).

• What changes: the mud is frozen or buried, which helps, but finding your way across the open bog becomes hard. Ushuaia Travel notes there have been rescues for disorientation in snow. Days are short: Civil Defense warns it is practically dark by 16:30–17:00 in midwinter, and INFUETUR’s start cut-off is 12:00.
• Walking on the ice: guided winter tours sometimes walk on the frozen lake. Never do it alone, or in early spring and late autumn when the ice is thinning.
• Avalanche caution: the standard route to the lake is low-angle, but the upper valley and the slopes toward Ojo del Albino and Cerro Bonete are avalanche terrain. Ushuaia’s Civil Defense issues avalanche alerts in some winters, and local experts note the risk rises on 30–45° snow slopes. A couple was buried by an avalanche near Laguna Turquesa, across the valley, in June 2025.
• Cost: guided winter treks run about ARS 135,000–160,000 (see the table above).

When is the best time to hike Laguna Esmeralda? (season by month)

Late November to April is best for hiking on your own. October and May are muddy shoulder months, and June to September is guided snow season.

October 2026: a hiker in mid-September found ice “desde el inicio del sendero” and needed crampons the whole way. In early October, carry microspikes (rent them in town) and gaiters. By late October expect mostly mud, with snow only near the lake. For weather, daylight and crowds in every month, see the Ushuaia best time to visit guide.

Gear checklist

• Waterproof, high-ankle hiking boots. Non-negotiable. Rubber boots work in pure mud but are poor on the rocky final climb.
• Gaiters, the cheapest upgrade for the turbal.
• Trekking poles, for balance in mud and on the descent.
• Microspikes or crampons from May to October, and snowshoes in deep snow (usually supplied on tours).
• Layers: base layer, fleece, waterproof jacket and pants, hat and gloves, even in January.
• Water (1–1.5 L), lunch and snacks. The stream is glacial, but it runs below busy campsites, so treat it.
• Offline map or GPX (AllTrails, Wikiloc or the official INFUETUR KML), a charged phone, a power bank and a headlamp.
• A trash bag. Pack everything out; nothing breaks down quickly in this climate.
• Spare socks and a bag for muddy boots for the ride back.

Where to rent in Ushuaia (2026): Ushuaia Extremo lists waterproof boots from ARS 12,000 and pairs of poles from ARS 10,000 in its 2026 tariff. Conocer Ushuaia sells chain crampons (ARS 60,000), and several agencies rent snow clothing (Yaghan Turismo from ARS 30,800). Prices change often, so confirm before you go.

Safety: what can go wrong and how to avoid it

Most incidents are slips on the descent, getting lost and people underdressed for sudden weather changes. All of them are avoidable.

• Tell someone your route and return time, and never hike alone in winter.
• Respect INFUETUR’s cut-off (15:00 in spring and summer, 12:00 in autumn and winter). It exists because rescues from the lake take hours.
• Turn around if snow hides the trail markers or cloud drops onto the bog.
• Stay on the marked path. Don’t remove or damage signs; INFUETUR stresses they keep people from getting lost.
• Hypothermia is the hidden risk: wet feet plus wind at the lake. In one night rescue reported by Tiempo Fueguino, involving 15–18 rescuers in two teams, Civil Defense director Cristian Álvarez said the man found with early hypothermia “había ingerido alcohol en el trayecto y se había metido al agua.”
• Emergency numbers: 103 (municipal Defensa Civil, which coordinates the Comisión de Auxilio), 107 (medical emergencies) and 911 (police). Signal is partial; if you can’t call, move to higher, open ground and try a text message.

Leave No Trace, beavers, dogs and drones

• Peat bogs take centuries to form. Stay on the boardwalks and the main trail.
• Beavers were introduced in 1946 and are an invasive species. Their dams have flooded and killed swaths of the forest you walk through.
• Dogs are not allowed (INFUETUR asks walkers not to bring pets).
• Drones: we found no specific Esmeralda rule. It is a provincial nature reserve with heavy foot traffic, and national drone rules (ANAC) apply. Fly considerately or not at all.

How does Laguna Esmeralda compare with other Ushuaia hikes?

If you have one hiking morning between November and April, Esmeralda gives the best view for the effort. If it has been raining for days and you don’t own good boots, do the Senda Costera in the national park instead, for firmer ground and ocean views.

Photo tips

• Morning light hits the lake and the glacier cirque best; afternoons are often backlit and windier.
• Cross the outflow and climb 20–30 m for the elevated shot with Ojo del Albino behind.
• Calm mornings in March and April give mirror reflections and red autumn lenga.
• In winter, expose for the snow (+1 to +1.7 EV) to keep the lake blue-white, not gray.

How to hike Laguna Esmeralda, step by step

1. Check the forecast and daylight the night before. Aim to start by 9:00, and never after 15:00 (spring and summer) or 12:00 (autumn and winter).
2. Rent or pack waterproof boots, gaiters and poles, plus microspikes from May to October.
3. Download the track for offline use (AllTrails, Wikiloc or the INFUETUR KML).
4. Book transport with a return time: a combi from Maipú and Fadul, a taxi or remis, or a rental car to the free km 18 car park.
5. Tell someone your route and expected return.
6. Walk the forest, bog and riverside sections (about 2 h), staying on the boardwalks.
7. Climb the final moraine to the lake, rest 30–45 minutes and add layers.
8. Do not continue to Ojo del Albino unless you are with a licensed guide.
9. Return the same way (about 1:45–2 h) and meet your ride.

Sample day plans

Plan A: morning hike and a Beagle Channel afternoon (summer). 08:30 combi or taxi to km 18 → 09:00–13:30 hike → 14:30 back in town for lunch → 15:30 afternoon Beagle Channel boat trip → dinner in town.

Plan B: hike and a lamb lunch in Tierra Mayor. 09:00 start → 13:00 back at the car park → late lunch at a Tierra Mayor valley restaurant (lamb, or cordero, on the menu; see where to eat in Ushuaia), or book a trek-plus-meal “Confort” product → evening in town.

Plan C: cruise or short stay. Esmeralda takes a long half day plus transfers. On a tight port call, choose a national park tour instead (see Ushuaia shore excursions).

Is Laguna Esmeralda in Tierra del Fuego National Park?

No. Laguna Esmeralda is in the provincial Valle Tierra Mayor reserve, about 18 km northeast of town, while the national park lies about 12 km west of Ushuaia. They are separate trips.

If you want the park too, pair it on another day with one of our best Tierra del Fuego National Park tours, such as the National Park & End of the World Train Tour (from $50, 4.5/5 from 1,216 reviews) or the Tierra del Fuego National Park Trekking & Canoeing day (from $184, 4.7/5 from 78 reviews). See the park guide, the entrance fee page and the End of the World Train guide.

A few caveats

• Prices are in Argentine pesos and change often with inflation. All figures were checked in 2026; confirm them before booking.
• Combi times and fares come from traveler reports and agency listings, not an official timetable. The newest municipal “Qué hacer hoy” sheets are the best place to check.
• Boardwalk totals differ between official statements (about 800 m vs 850 m) and appear to be cumulative.
• INFUETUR gives the autumn and winter cut-off as 12:00; some AllTrails notes say 13:00. Follow the official sign.
• Taxi fares are our meter-based estimate; Uber fares come from an undated press guide.
