What makes the Mayo Arm different from other parts of Los Glaciares?

The Mayo Arm (Seno Mayo) is one of the park's wettest sectors, resulting in unusually lush Patagonian Andean forest vegetation and numerous waterfalls and rivers not visible on standard glacier tours.

How difficult are the walks?

Both forest walks are low difficulty, designed for mixed fitness levels and all audiences. No climbing or technical hiking experience is required.

Do we see Perito Moreno Glacier?

Yes. The tour includes boat navigation to Perito Moreno Glacier with access to the standard walkways, combined with exploration of the more remote Mayo Arm.

Wear waterproof jacket, sturdy closed-toe hiking boots, and bring sun protection, water, and snacks. The forest can be muddy and weather changes quickly in Patagonia.

How long is the full experience?

The total experience is 10 hours, including boat transport, two guided forest walks, and glacier navigation. Plan for an early start and full-day commitment.

Is this tour accessible for families?

Yes. Low-difficulty walks and mixed-ability pacing make this suitable for families with children and mixed fitness levels.

About this activity

Navigate remote glacial inlets of Lake Argentino to reach the rarely visited Mayo Arm, where two guided forest walks reveal verdant Patagonian woodland, cascading waterfalls, and hanging glaciers inaccessible to most park visitors. This 10-hour expedition combines boat exploration with low-difficulty hiking, culminating in close views of the iconic Perito Moreno Glacier.

Our navigation will take you to know one of the most beautiful places in Los Glaciares National Park, which only a few people have the privilege of accessing: the May Sine of Lake Argentino.
The Seno Mayo (or Brazo Mayo), is one of the wettest sectors of the National Park, that is why the vegetation that can be seen during the two walks (which we will do in the Patagonian Andean forest) is totally different from the one that observes in other places Park.
The "Mayo Spirit Trek" is the perfect combination of hiking in the forest, overlooking waterfalls, rivers, hanging glaciers and visiting the Perito Moreno glacier (navigation + walkways). Suitable for all audiences, with low difficulty walks, it makes our passengers happy with our excursion.
