Perito Moreno Glacier: A Complete Guide to Visiting

The Perito Moreno Glacier is, without exaggeration, one of the most jaw-dropping natural sights you’ll ever witness in Patagonia. A wall of ice roughly 60 meters tall above the water that advances, groans and calves off in blocks that crash into the lake with a roar you feel in your chest. As a local tour operator based in El Calafate, we visit it year-round, and in this complete guide we’ll share everything you need to know to plan your visit and make the most of it.

What it is and why it’s unique

Perito Moreno is a glacier located inside Los Glaciares National Park, in the southwest of Argentina’s Santa Cruz province. It’s part of the Southern Patagonian Ice Field, the third-largest freshwater reserve on the planet after Antarctica and Greenland. Its front is about 5 kilometers wide and its surface spans more than 250 km², a scale that’s hard to grasp until you’re standing right in front of it.

What truly sets it apart is its dynamics. Unlike most glaciers in the world, which are retreating at an alarming rate, Perito Moreno maintains a remarkable balance: it advances several meters a day at its front (part of that ice calves off and offsets the advance). That constant movement is exactly what causes its famous calving events: chunks of ice the size of buildings that break away and plunge into Lake Argentino.

The glacier ruptures

Every so often, the glacier’s front advances until it touches the Magallanes Peninsula on the opposite shore. That contact forms an ice dam that separates the Brazo Rico from the rest of Lake Argentino. The water in the Brazo Rico rises until the pressure becomes so great that the ice breaks apart in a monumental spectacle: the famous Perito Moreno rupture. It’s not an event with a fixed schedule (it can happen every few years, and not always in the same season), so no one can guarantee you’ll see it. But even without a rupture, the everyday calving is reason enough to visit.

Los Glaciares National Park

The glacier sits within Los Glaciares National Park, created in 1937 and declared a UNESCO World Heritage Site in 1981. The park is home to dozens of glaciers beyond Perito Moreno, and it splits into two main areas: the south, with El Calafate as its gateway and Perito Moreno as the headline act, and the north, home to El Chaltén and the towering Mount Fitz Roy.

To enter the glacier area you pay a park entrance fee, collected on arrival and usually updated each season. We recommend checking the current rate at the time of your trip, as it can change; on our excursions we always let you know what each departure includes.

Ways to visit Perito Moreno

One of the best things about Perito Moreno is that there’s a way to experience it for every kind of traveler. Here are the main ones.

Boardwalks and balconies

The boardwalks are a network of trails and balconies at various levels built on the Magallanes Peninsula, right across from the glacier’s front. From here you see it up close, without walking on the ice, making it the ideal option if you’re traveling with kids, older relatives, or simply want to take it in at your own pace. There are routes of different lengths and difficulty, all very accessible. This is the basis of our classic Perito Moreno Glacier tour, designed for those who want to experience it from the viewpoints.

Boat cruises

Boat cruises bring you close to the ice wall by water, a completely different perspective from the boardwalks. From the deck, the scale of the glacier becomes overwhelming: those 60 meters above the lake only truly hit you when you’re at water level. It’s a calm, photogenic experience and pairs perfectly with a boardwalk visit.

Mini-trekking

If you want something more active, the mini-trekking is the star experience: a guided walk on the glacier’s ice wearing crampons, led by professional guides. You cross the lake by boat, get fitted with gear, and walk among crevasses, blue pools and ice formations that look like another planet. No previous experience is required, just reasonable physical fitness. Check the details and requirements on the mini-trekking page: for many of our travelers, it’s the single most memorable moment of the trip.

Kayaking

For the more adventurous, kayaking in front of the glacier is one of the most intimate ways to experience it. You paddle among floating ice, in silence, with the wall of ice dominating the horizon. It’s a guided activity with all the equipment included. Discover the full experience on Perito Moreno kayak.

Big Ice and other experiences

For those after a longer, more demanding ice trek, there’s the Big Ice, which ventures deeper into the glacier and usually has stricter age and fitness requirements. And if you’d like a broader view of the surroundings, the Safari Azul combines different perspectives of the glacier and its setting. Each departure has its own difficulty level and season, so we suggest checking availability and price on each excursion’s page.

Best time to visit

The good news is that Perito Moreno can be visited year-round. Each season has its own charm:

• Summer (October to April): this is high season. Long days, milder temperatures and all activities running, including mini-trekking, Big Ice and kayaking. It’s the best time if you want to walk on the ice or take a boat cruise. It’s also the busiest, so booking ahead is wise.
• Winter (June to September): the landscape is blanketed in snow and the glacier takes on a magical feel, with fewer people and beautiful light. Some on-ice activities may run less frequently or not at all, but the boardwalks and simply taking it all in are still spectacular.

In any case, remember that Patagonian weather is highly changeable and windy: in a single day you can get sun, clouds, strong wind and even some rain or snow. It’s all part of the experience.

General hours

Access to the glacier area follows the park’s opening hours, which vary by season (in summer the day runs longer thanks to extra daylight). Excursions usually depart from El Calafate in the morning and return in the afternoon. For exact departure times, it’s best to check each tour’s page, as they change throughout the year.

What to pack

Good preparation makes all the difference against the Patagonian weather. We recommend bringing:

• Layered clothing: a thermal base layer, a mid layer (fleece or similar) and a windproof, waterproof jacket. Wind is the factor you’ll feel the most.
• Comfortable, waterproof footwear for walking the boardwalks. For mini-trekking and Big Ice, crampons are fitted over your own footwear, so you’ll need sturdy hiking boots (check each activity’s requirements).
• Gloves, a hat and a neck gaiter or buff, even in summer: it always gets colder near the ice.
• Sunscreen and sunglasses: the glare off ice and snow is intense.
• Water and a snack, depending on how long your outing is.
• A camera or phone with a charged battery: the cold can drain it faster than usual.

How to get there from El Calafate

The Perito Moreno Glacier is about 80 kilometers from El Calafate, roughly an hour and a half along Provincial Route 11, a paved road in excellent condition that winds through steppe and forest as you approach the park.

El Calafate is the perfect base: you fly into Comandante Armando Tola International Airport (FTE), with flights from Buenos Aires and other cities, and from there you arrange your entire visit to the glacier. Most of our excursions include round-trip transfers from your accommodation or a meeting point in town, so there’s no need to rent a car or worry about logistics.

If your plans include more of Patagonia, from El Calafate you can also combine with El Chaltén (the country’s trekking capital, about 3 hours away via Route 40) to add some mountains to your trip.

Our final recommendation

Perito Moreno can be enjoyed in many ways, and the best one depends on what kind of traveler you are. If it’s your first time, the boardwalks combined with a boat cruise give you a complete picture. If you’re after adrenaline and an unforgettable memory, mini-trekking or kayaking are sure bets. And if you have several days, combining experiences is the smartest choice.
