Martial Glacier: Ushuaia Travel Guide (4.8★)

A glacier you can see from town

From Ushuaia’s waterfront, look uphill. The white tongue of ice in the cirque above the rooftops is Martial Glacier, and it is close enough to walk to before lunch.

It belongs to the Martial range (Montes Martial), named after Louis-Ferdinand Martial, who commanded the French scientific expedition that wintered here in 1882–83. In summer the slopes are bare rock, scree and low southern beech scrub. In winter the lower slopes hold a small ski area with a chairlift. That makes it a smaller, closer alternative to Cerro Castor, the region’s main resort, which lies further out along Route 3.

This is a well-known excursion, not a secret. Expect other hikers on the trail on any clear summer day.

The climb, step by step

The road climbs out of town in switchbacks to the base area at the end of the glacier road. Most visitors take a taxi or remise from the centre. Walking up adds roughly an hour each way on tarmac.

From the base, the trail follows the valley upward:

• Lower section: a broad, steady path through stunted lenga forest.
• Middle section: the trees thin out and the path turns to loose gravel and scree beside a meltwater stream.
• Upper viewpoint: a rocky bench below the ice, looking straight down the valley to Ushuaia, the Beagle Channel and the Chilean peaks of Isla Navarino.

The glacier has retreated a long way. What you reach is a hanging glacier and snowfields, not a calving wall. The view back toward the sea is the real reward.

Weather, gear and timing

Tierra del Fuego weather turns within the hour, so pack for it. Wind on the upper scree is stronger and colder than anything you felt in town.

• Layers: a windproof shell plus a warm mid-layer, even in January.
• Footwear: boots with grip, because the scree is loose on the way down.
• Water and food: carry your own for the upper section.
• Season: December to March gives the longest daylight and a snow-free trail. From roughly June to September, the lower slopes become the ski area.

Start in the morning. That way, if cloud drops onto the ridge, you still have hours left to wait for it to lift.

Walking it the Fuegian way

People here treat Martial as a casual afternoon hike, yet they respect the mountain. Stay on the marked trail. Shortcuts across the scree erode the slope and send rocks onto hikers below.

Do not walk out onto the ice itself. Snowbridges and meltwater channels are invisible from above, and rescue up here is slow. The viewpoint below the ice is where everyone turns around.

For taxis, agree on a pickup time before the driver leaves the base, because phone signal on the upper trail is unreliable. Fares are posted or quoted by the driver; pay in Argentine pesos. If the chairlift or ski area matters to you, check its current status in town before going up, since operations change from season to season.

Pack out everything you carry in, including fruit peel. Nothing breaks down quickly at this altitude and latitude.
