This guide will cover the core decision between the tours, essential planning advice on booking and gear, the deeper glaciology context, and a clear verdict to help you choose. Let’s find the right trek for you.

At a Glance: The Definitive Comparison Table

This table provides a quick, scannable summary to help you immediately grasp the fundamental differences between the two main glacier walking tours. It covers the most critical decision-making factors for any hiker planning this beautiful hike.

The Core Decision: A Hiker’s Breakdown of Each Tour

Understanding the itinerary is one thing; understanding the experience is what matters to a hiker. Here, we deconstruct each glacier tour to reveal its true character, helping you align your choice with your personal hiking identity.

The Minitrekking Experience: An Introduction to the Ice

This tour is perfectly designed as a high-quality “taster” experience, making the extraordinary activity of an ice walk accessible to a broad audience. The excursion lasts about 10 hours, with the core activity being a 1.5-hour mini-trek on the ice itself. This offers a taste of walking on a glacier and is an efficient way to get iconic photos and feel the unique sensation of crampons.

The day includes a bus transfer, a 20-minute boat ride across Lago Argentino, and a pleasant 30-minute stroll through a subpolar Magellanic forest to the glacier base at the ice margin. The on-ice portion of the popular Perito Moreno Mini trekking explores the periphery, offering incredible views of smaller crevasses and seracs under the close supervision of guides. While rated moderate, walking on an undulating, hard surface with crampons is a novel experience. This tour is ideal for those who are suitable for families and beginners or hikers conserving energy for other Patagonian wilderness treks.

The Big Ice Experience: A True Hiker’s Challenge

The Big Ice tour is a fundamentally different product, crafted specifically for the fit, experienced senderista who prioritizes challenge and immersion. It is a grueling, 12-hour day with over 7 hours of continuous, strenuous walking. This big trek is designed to feel less like a tour and more like a genuine polar expedition.

The critical differentiator is the approach. The Strenuous Moraine Hike is a demanding 1.5 to 2-hour ascent up the glacier’s steep and rocky southern moraine. This section alone is a significant trek over loose scree and rocky hills, requiring good balance and fitness. It acts as a filter, ensuring a group of capable hikers ready for epic mountain hikes. For those focused on progressing to more challenging trails, this is the clear step up.

Once on the ice, you spend 3 to 3.5 hours exploring the icy landscape. Smaller groups allow guides to lead you into the heart of the ice, navigating massive, deep-blue crevasses, cool ice caves, and stunning moulins that are inaccessible on the shorter tour. The lunch break in the middle of the immense ice field is an unforgettable highlight.

The New Contender: What is “Minitrekking 2”?

Recent traveler reports suggest the quiet introduction of an intermediate option, a sort of second glacier walk sometimes called “Minitrekking 2.” Official information is limited, but this tour appears designed to bridge the gap between the two classic options. It reportedly offers a longer walk on the ice than the standard Minitrekking but crucially does not include the formidable moraine hike of the Big Ice tour.

This potential option could be an excellent value for hikers who want more time exploring the ice but do not meet the stringent age or fitness requirements for the Big Ice trek. The age limit is reportedly 18-55. Given the emergence of a potential third option, it’s best to inquire about this specific glacier trekking option directly with the tour operator when booking.

Planning Your Trek: A Practical Guide for Hikers

Moving from decision to action requires careful planning. We’ve gathered the essential logistical and preparatory information to ensure your Perito Moreno glacier walk is safe, comfortable, and cost-effective.

Booking Your Tour: The Smart Way

One company, Hielo y Aventura, has the exclusive concession to operate treks on the Moreno glacier. Any other agency is simply a reseller. The most direct method is to book via the official Hielo y Aventura website, and it is wise to book well in advance for peak season (December-February).

For international travelers, paying in Argentine Pesos (ARS) with a foreign credit card can lead to significant savings. This method often uses the more favorable “MEP rate.” Always check the latest payment policies, but booking online is usually the most cost-effective strategy. This is a significant investment, but it covers expert guides, safety gear, and the logistics of operating in a national park. The strict age and health rules are non-negotiable.

Essential Gear: A Hiker’s Checklist for the Glacier

Your choice of footwear is the single most important gear decision. You must wear sturdy, waterproof hiking boots with good ankle support. The crampons need a solid platform; sneakers are unsafe. Knowing the specific clothing and gear to wear is just as important for your comfort on the ice.

A proper layering system is required for the unpredictable Patagonian microclimate. Start with a moisture-wicking base layer, add a fleece mid-layer, and top it with a fully waterproof and windproof outer shell. Waterproof pants are highly recommended. Key accessories are mandatory: high-UV-rated sunglasses, gloves, a warm hat, sunscreen, and a small backpack (20-40L). The operator provides all technical gear, so you won’t need your own ice-picks.

Fitness & Preparation: Are You Ready for the Ice?

For Minitrekking, a moderate level of fitness is required. You should be comfortable with a few hours of walking on uneven ground. While not intensely cardiovascular, some people may find the crampon portion challenging as it uses different muscles.

The Big Ice tour demands a high level of physical fitness, endurance, and previous hiking experience. You must be prepared for a 12-hour day where the hike takes a full day with over 7 hours of continuous, strenuous walking on difficult terrain, including the steep moraine. This is not a suitable choice for sedentary individuals.

The age limits (10-65 for Minitrekking, 18-50 for Big Ice) are strictly enforced. Honesty in your self-assessment is critical for your safety and the group’s enjoyment.

Logistics & Fees: What’s Not Included

The Los Glaciares National Park entrance fee is not included in your tour price and must be paid separately. As of early 2025, the fee for this park is substantial, so budget for it. Keep your ticket for a 50% discount on the entrance fee for the following day.

No food or drinks are provided during the full-day excursion, aside from the final whiskey toast. You must bring your own packed lunch, snacks, and sufficient water for a long, active day. After your tour, consider a visit to the Glaciarium Ice Museum in the nearby mountain town of El Calafate to deepen your understanding.

Beyond the Itinerary: Understanding the Glacier You’re Walking On

For a dedicated hiker, the ‘why’ and ‘what’ are as important as the walk itself. Gaining the deeper context behind the trek is what transforms a great tour into a truly meaningful wilderness experience.

The Glaciology of Perito Moreno: A Story of Change

This massive glacier, named after the explorer Francisco ‘Perito’ Moreno, covers 250 square kilometers, fed by the vast Southern Patagonian Ice Field. It is part of the Andes mountain ranges. For decades, it was famed as one of the very few glaciers, unlike others such as New Zealand’s Fox Glacier, that was stable or advancing.

Recent analysis shows this has shifted. The glacier has entered a state of retreat. While its center still advances, causing spectacular ice calving events where massive icebergs calve from the front, its overall volume is shrinking. During your trek, you’ll see key geological features on the ancient ice, from deep cracks called crevasses to ice pinnacles known as seracs. The thunder of ice breaking from the 70-meter-high glacier face is a powerful reminder of nature’s force.

Other Ways to Experience the Glacier

If glacier trekking isn’t feasible, there are still fantastic ways to experience the famous Perito Moreno. The network of scenic walkways (pasarelas) is an attraction in its own right. This 4-5 km system of boardwalks provides breathtaking, panoramic views of the entire ice cliff wall. This whole area is part of a protected UNESCO World Heritage site.

The “Safari Náutico” is a one-hour boat trip along the southern wall. It offers a different perspective, bringing you close to the towering, icy cliffs. This is an excellent add-on or alternative. For a more active option, consider kayaking tours. Paddling on Lago Argentino provides a uniquely intimate encounter. These are just a few of the many other Patagonian adventures available in the region, which also boasts highlights like the jagged granite mountains near Fitz Roy.

The Verdict: Which Perito Moreno Glacier Walk is for You?

The choice between the Minitrekking and Big Ice hike is a choice of identity. It’s not about which is “better,” but which experience aligns with your goals as a hiker.

Choose Minitrekking if: Your primary goal is to experience walking on a glacier, you’re new to this type of activity, you’re traveling with people of varied fitness levels, or you’re constrained by budget or the strict Big Ice age limit. It is a fantastic, well-organized, and unforgettable tour that delivers the “wow” factor.

Choose Big Ice if: You define yourself as a dedicated hiker who seeks out physical challenges and values immersion over convenience. If you believe the best views are earned through effort and you want a deeper, less-crowded, and more comprehensive exploration of this natural wonder, then the Big Ice is the only option that will truly satisfy your adventurous spirit.

For the serious senderista, the extra cost and effort of the Big Ice are justified by a more challenging and rewarding expedition. It trades the “tourist taster” feel for a genuine sense of adventure in the heart of the ice.
