Dec – Feb
Patagonian summer
The long-daylight months, and the stretch in which a twelve-hour day is most comfortable. It is also the busiest: book well ahead, this is a small group.
Big Ice
Big Ice is the longest day anyone sells on the Perito Moreno Glacier: twelve hours from El Calafate, a small group, a guided forest trek to the edge of the ice, sailing in front of the glacier wall, and then a long guided hike across the glacier in crampons before the walkways at the end. It costs $588, it is rated 4.9 across 53 reviews — the highest rating of all sixteen tours on this site — and it is the only listing built around the crossing itself rather than around a single hour on the ice.

Quick answer
The short answer. Book the $588 El Calafate: Perito Moreno Glacier Big Ice Trek. Twelve hours, small group, hotel pickup and drop-off from centrally located hotels in El Calafate, hiking equipment supplied, sailing in front of the glacier wall, a guided forest trek, the long guided hike across the ice and a guided visit to the walkways. It is the fullest access to the glacier surface sold from El Calafate. If twelve hours is more day than you have, the $399 Trekking Tour and Cruise gives about an hour on the ice inside eleven hours instead.
What it is
Twelve hours buys distance across the ice. That is the entire proposition.
A search for big ice perito moreno usually starts from a photograph: a line of walkers in crampons, small against ice that runs to the horizon, somewhere out in the middle of the glacier rather than at its edge. That photograph is what this listing sells, and the twelve hours in the title are the price of getting there.
The shape of the day is fixed by geography. Perito Moreno sits inside Los Glaciares National Park, on Brazo Rico, the southern arm of Lago Argentino, and every tour begins with the road out of El Calafate. On the Big Ice listing that road is covered by hotel pickup and drop-off from centrally located hotels. Then comes sailing in front of the glacier wall, a guided trek through Patagonian forest to the point where the ice meets the land, and the crampons. After the ice, the day finishes with a guided visit to the walkways of the glacier, which is where most people spend their entire visit.
What separates Big Ice from a mini trek is not the equipment or the guide — both formats supply those. It is distance. A mini trek, like the $450 MiniTrekking listing, is approximately an hour on the ice near the edge, on the gentler ground where the glacier first meets the shore. Big Ice keeps walking: further from the edge, deeper into the broken surface, across ridges and around the sinkholes and cracks that give the ice its colour. Everything you have read about the blue inside a glacier belongs to the part of the day that only this format reaches.
It is also a small-group listing, and the rating reflects what that does to a walk on broken ground: 4.9 across 53 reviews, the best score of any tour on this site. Fifty-three is not a huge sample, and it should not be read as one — but it is the sample from the hardest day sold here, and nobody books a twelve-hour glacier crossing by accident.

The day in detail
Boat, forest, ice, boardwalks. The listing does not skip a stage and does not pad one.
The pickup. Hotel pickup and drop-off from centrally located hotels in El Calafate is in the fare. You are not driving into the national park, not parking, and not buying a park entry separately at the gate — the day is handled from the door of your hotel and back to it.
Sailing in front of the glacier wall. Before the walking, the boat. Brazo Rico is the arm of Lago Argentino that runs along the southern face, and the crossing doubles as the first proper view: the wall from water level, at the scale it actually is. Blocks of ice fall from the front into the lake, and the sound arrives a moment after the sight. Every trekking listing includes this leg, because it is also how you reach the trekking shore.
The guided forest trek. From the landing, a trail through Patagonian forest to the edge of the ice. This is the part nobody photographs and everybody remembers: the temperature dropping as you approach, and the first ridge of grey-blue ice appearing through the trees.
The crossing. Hiking equipment is supplied, the guide fits the crampons, and the group goes out. This is the leg that makes the listing what it is. The route moves away from the edge and into the body of the glacier — up and over ridges, along the lips of cracks, past sinkholes where meltwater has cut down into the ice and left the deep blue behind. The pace is set by the guide and the group is small, which on this ground is not a comfort feature but the reason the day works at all.
The walkways. The day closes with a guided visit to the boardwalks and balconies facing the glacier front. Having just walked on the surface, the view from the railing reads completely differently: you can see the line you took, and how small it was against the whole face. Every tour on this site includes the walkways; this is the only one that puts them at the end of a full crossing.
The return. Drop-off at your hotel in El Calafate. Twelve hours, door to door — an honest number for a day with a boat, a forest, a glacier crossing and the walkways inside it.
The verdict
Big Ice is not a longer mini trek. It is the only listing that crosses the glacier.
Book Big Ice if the glacier surface is the reason you are going to Patagonia. At $588 it is the most expensive listing on this site, and what the fare buys is unambiguous: the longest guided walk across Perito Moreno that anyone sells, in a small group, with the boat, the forest and the walkways attached rather than removed. It is also the best-rated tour here at 4.9. There is no cheaper way to spend that long on the ice, because no cheaper listing goes that far out.
Book the $399 Trekking Tour and Cruise if you want the ice and the cruise in one eleven-hour day. It gives approximately an hour hiking on the glacier with crampons, a sightseeing cruise in front of the glacier, the forest and the boardwalks, with one guide for every ten guests — and it carries 852 reviews at 4.8, the deepest record on the site. It is the complete day; Big Ice is the deep one.
Book the $450 MiniTrekking or the $520 Ice Trekking if ten hours is your limit. Both fit crampons and put you on the surface. MiniTrekking names the cracks, sinkholes and shades of deep blue; Ice Trekking spends more of the day on the glaciology of the front wall.
One thing not to do: compare Big Ice with the walkway tours on price. The $60 national park tour and the $69 classic day are rated 4.7 by thousands of visitors and they are the right booking for someone who wants the view. They are a different product. Between two ways of standing on the glacier, the longer one is not the expensive version of the shorter one — it is the one that goes where the photographs come from.

When to go
A twelve-hour small-group day needs daylight and it needs a seat. Those two things move through the year in opposite directions.
Dec – Feb
The long-daylight months, and the stretch in which a twelve-hour day is most comfortable. It is also the busiest: book well ahead, this is a small group.
Mar – Apr
Quieter at the walkways and easier to book. The crossing is the same crossing, and the park is emptier at the railings afterwards.
May – Aug
Short days in the far south. Check the listing calendar before building a trip around this window, and lean on the free cancellation while you plan.
Sep – Nov
Daylight returning, availability still open. A sensible target if your dates flex and you want the twelve-hour day without booking months out.
Before you book
Nothing here is a warning. All five are the difference between the right booking and a near-miss.
Pack this
The operator brings the hiking equipment, the guide and the boat. This is your half of the list.
Firm sole, ankle support, already worn in. The single most important item for the longest walk on the ice sold here.
A vehicle, a boat, a forest and a glacier in one day. You will open and close the jacket several times before lunch.
Open water on one side and the Patagonian steppe on the other. The wind, not the ice, is what people remember.
Twelve hours of bright light with several of them on white ice, and a hand on a pole for much of it.
Twelve hours door to door. Pack for it rather than counting on a stop.
Book the date early — this is a small group — and keep the cancellation window as room to move.

Common questions
A twelve-hour small-group day from El Calafate built around a long guided hike across the glacier in crampons. Hotel pickup and drop-off, sailing in front of the glacier wall, a guided forest trek, the ice crossing and a guided visit to the walkways are all in the $588 fare.
$588, with hiking equipment, the guide, the boat and hotel pickup included. It is the highest fare of the sixteen tours here and the longest day on the glacier.
Big Ice runs twelve hours and is built around the crossing itself. A mini trek — the $450 MiniTrekking or the $399 Trekking Tour and Cruise — gives approximately one hour on the ice inside a ten to eleven hour day.
They answer different questions. The walkways are included in every tour on this site and show you the front of the glacier from balconies. Big Ice is the only listing that takes you deep onto the surface, and it is rated 4.9 — the highest score here.
Yes. Sailing in front of the glacier wall is named in the inclusions, along with the guided forest trek, the guided glacier hike, the guided walkway visit and the hiking equipment.
The listing asks for at least 10 hours in advance, but it is a small-group day with 53 reviews behind it rather than a mass departure. Book the date as soon as your plans are firm and use the free cancellation if they change.
