Perito Moreno glacier tours compared: which one to book

Key Takeaways

• Perito Moreno sits inside Los Glaciares National Park and ends in Lago Argentino, about 80km from El Calafate on the paved Ruta Provincial 11.
• The ice front runs roughly 5km wide and 60 metres high.
• It was long one of the few glaciers that held steady while about 90% of Patagonia’s glaciers have been shrinking (The Conversation, 7 August 2025); the same research found it has now started retreating too.
• The park’s walkway circuit covers more than 4.5km, with an elevator connecting different levels and a ramped, accompanied path for wheelchair users.
• Mini trekking has a minimum age of 8; Big Ice is restricted to ages 18 to 50 and requires a signed medical form, per Lati Travel’s own booking terms for each tour.
• Two tours view the glacier’s face from platforms and water, two put you on the ice, and one, Estancia Cristina, trades the glacier for a longer day further into the lake.

Perito Moreno glacier: where it is, and why it’s unusual among glaciers

Perito Moreno sits inside Los Glaciares National Park, in Santa Cruz province. It ends in Lago Argentino after descending through beech forest, per The Conversation’s coverage of recent glaciology research. It draws around 700,000 visitors a year, the same article reports. That makes it the park’s main destination by a wide margin.

The ice front itself runs about 5km wide and 60 metres high above the water. That scale is hard to read from photos alone. It’s part of why the boat tours exist alongside the walkways.

What made Perito Moreno unusual for decades was its refusal to retreat. About 90% of Patagonia’s glaciers have been shrinking. Perito Moreno held roughly the same position for most of the last century instead. Researchers linked that stability to the shallow water where it meets the opposite shore of the lake. That reputation is now out of date. The same 2025 research found its surface has lowered sharply in recent years, and that it has started retreating too. The glacier is still there and still calving. It’s just no longer the exception it used to be.

Perito Moreno glacier tours compared: what each one involves

Lati Travel runs five distinct ways to see the glacier, and they don’t overlap much. Pick by how close you want to get to the ice, and how much walking you’re up for.

Tour	What it involves	Duration	Fitness / age	Price (per person)
Walkways & Nautical Safari	Panoramic walkways plus a short boat crossing along the ice wall	9 hours	Easy, no age limit	From US$103
Boat Blue Safari	Boat crossing, a guided forest walk, then time on the walkways	8 hours	Easy, no age limit	From US$131
Mini Trekking	Boat across Lake Rico, a walk through forest and moraine, then about an hour on the ice in crampons	9.5 hours	Moderate, minimum age 8	From US$274
Big Ice	A longer boat and moraine approach, then a deeper route through the glacier’s crevasses and caves in crampons	12 hours	Demanding, ages 18-50, medical form required	From US$396
Estancia Cristina Navigation	Sail Lago Argentino past icebergs to a ranch reached only by boat; optional 4x4 to a glacier viewpoint or a Fossil Canyon hike	8 hours	Easy, trekking add-on is demanding	From US$225

The walkways and boat safari: the standard visit

The Walkways & Nautical Safari is the most booked of the five, and it’s built for the widest range of visitors. Lati’s tour departs El Calafate hotels at 08:30am with a bilingual guide for the drive to the park. It then puts you on the walkway circuit in front of the glacier, before the boat crossing along the ice wall.

The circuit itself is a park facility, not something specific to any one tour operator. It covers more than 4.5km of platforms across the different viewpoints. An elevator connects the different levels. A ramped path is available for wheelchair users who bring someone to accompany them. The floor is metal grating, which is why the park recommends trekking shoes with ankle support rather than open sandals.

The Boat Blue Safari covers similar ground with more time on the water: a boat crossing, a guided walk through Patagonian forest, then the walkways, in a shorter 8-hour day. It suits travellers who’d rather spend the extra time on the boat than on the platforms, without the ice trekking of the other three tours.

Mini trekking vs Big Ice: walking on the glacier itself

Mini Trekking and Big Ice both put crampons on your feet, but they’re built for different travellers. Mini Trekking crosses Lake Rico by boat, then walks through forest and moraine to reach the ice. From there, it’s about an hour on the glacier itself, past crevasses and meltwater pools. Its minimum age is 8, and Lati lists it as moderate difficulty.

Big Ice goes further into the glacier. After the boat crossing, a demanding hike along the moraine leads to a longer route through ice walls, meltwater lagoons and deeper crevasses, with roughly seven hours of trekking in total. Because of that physical demand, it’s restricted to ages 18 to 50 and requires a signed medical form before booking. It also runs longer overall: 12 hours against Mini Trekking’s 9.5. Both include a stop at the panoramic walkways as part of the route.

Neither tour is a decision to make lightly if you’re unsure of your fitness. The moraine sections are uneven underfoot before the ice even starts, and there’s no shortcut back once the group is on the glacier.

Estancia Cristina: the longer day further into the lake

Estancia Cristina Navigation isn’t a glacier tour so much as a different day out that happens to start from the same dock. It sails up Lago Argentino past icebergs to reach Estancia Cristina, a historic Patagonian ranch with no road access. Once there, the choice is between exploring the estancia’s history, taking a 4x4 up to a panoramic glacier viewpoint, or hiking the Fossil Canyon, which Lati flags as recommended only for experienced hikers given its physical demand.

It runs 8 hours, the same as the Boat Blue Safari. The glacier here is a distant view from a lookout, though, rather than the close approach the other four tours are built around. It’s the option for a second day in El Calafate once the standard glacier visit is already booked, not a replacement for it.

Perito Moreno glacier tours compared: which one to book

Short on time, travelling with a mixed-fitness group, or visiting with kids: the Walkways & Nautical Safari covers the glacier properly in a single day, with no fitness bar to clear.

Want to stand on the ice without committing to a full trekking day: Mini Trekking is the shorter of the two ice tours, with a minimum age of 8 rather than an adults-only cutoff.

Set on the longest route onto the glacier, and comfortable with the age and medical-form restrictions: Big Ice is the one built for that. It’s worth checking availability before planning a day around it, since Lati books it by quota.

Staying in El Calafate more than one day: pair the standard glacier visit with Estancia Cristina for a second day that trades ice for lake and history. Our El Calafate place guide covers the rest of the town, including the steppe excursions that don’t involve the glacier at all. For the trekking side of Patagonia, El Chaltén is the base further north in the same park. And if the trip isn’t locked to fixed dates yet, our Patagonia season guide covers when the wind and daylight work in your favour.
