Perito Moreno Glacier: Argentina's Advancing Ice Wall

Perito Moreno Glacier sits 78 km west of El Calafate in Los Glaciares National Park, reached in about 90 minutes via Ruta Provincial 11. It is one of the very few glaciers on earth still in equilibrium — its 5 km-wide face advances roughly two metres a day, and the ice wall rises 60 to 70 metres above Lago Argentino. Those numbers sound abstract until a house-sized block peels off and hits the water with a crack that rolls across the lake like thunder.

The glacier covers about 250 km², which makes it larger than the entire city of Buenos Aires. It is fed by the South Patagonian Ice Field, the third-largest freshwater reserve on the planet, and it has been a UNESCO World Heritage site since 1981. Around 650,000 people visited the park last year — a reminder that this is not a hidden corner of Patagonia.

Getting There and Planning Your Day

From El Calafate by bus or car

Public buses leave El Calafate twice daily, roughly 8:00 and 13:00, returning around 14:00 and 18:00. A round trip costs about 50,000 Argentine pesos and takes 1.5 hours each way. If you drive, the road is paved the whole way and parking at the walkways is free.

My advice: take the morning bus. Tour groups start arriving between 11:00 and 12:00, so an early arrival buys you roughly two quiet hours on the boardwalks before the platforms fill up.

Park entry fees

The day pass for foreign visitors runs around 45,000 to 50,000 ARS as of 2026 (about 30 to 40 US dollars). Buy it online through the Parques Nacionales website up to the day before, or pay in cash or by card at the entrance gate. Note that the fee is not included in any guided tour price, and rates are adjusted periodically for peso fluctuation — check the official site before you travel.

Season and weather

October through April is the sweet spot: warmer temperatures (5–15°C), long daylight, and the highest frequency of calving. December to February is peak season with 16 hours of light but also the biggest crowds. Winter visits from June to August are possible and the glacier looks dramatically different under snow, but some ice-trek operations close and winds get fierce.

What to Do Once You're There

The boardwalk circuit

A four-kilometre network of metal-grated walkways links several viewing balconies at different heights and angles. The gradient is gentle and there are only a handful of stair flights, so most visitors — including older travellers and children — manage it comfortably. Benches appear every few hundred metres. Colour-coded markers on the path correspond to the map, which makes it easy to track where you are.

Glacier viewing is not a quick stop. Give yourself at least three hours on the walkways; photographers will want more.

Boat trips and the Blue Safari

The one-hour Safari Náutico crosses Brazo Rico and approaches within 150 metres of the southern ice wall. It costs roughly 30 to 50 US dollars on top of park entry and runs year-round. A lower-key alternative is the Blue Safari, which combines a boat crossing, a 1.5 km walk along a pebble beach, and — unusually — a spot where you can actually touch the ice. Both are worth it if you want the scale of the wall from water level rather than from above.

Ice trekking: Minitrekking and Big Ice

Minitrekking puts you in crampons for about 1.5 hours on the ice after a short forest walk and boat crossing. It operates roughly August to May, takes nine to ten hours door to door, and costs 180 to 260 US dollars. Big Ice is the deeper version — around three hours on the glacier, a longer approach, and stricter fitness requirements (ages 18 to 50).

Both sell out one to three months ahead in high season. Book directly with the operator (Hielo & Aventura runs the concessions) rather than through a reseller — travellers report paying 100 US dollars or more in markup on the same trip.

Practical Rules and Safety

Do not climb over the railings. Signs at multiple points say so, and rangers do enforce it; people have been caught dropping onto the shore for photos. The calving ice creates sudden waves and the shoreline is genuinely dangerous.

Drones are banned throughout the park, with heavy fines. Pets are not permitted. Weather shifts fast at any time of year, so carry a waterproof layer, gloves, a hat, and sunglasses — the UV off the ice is brutal even on overcast days.

Food options inside the park are limited and expensive. Pack lunch and water the night before; there are restaurants and restrooms near the walkways if you'd rather buy.

Frequently Asked Questions

How much does it cost to visit Perito Moreno Glacier?

Park entry is about 45,000–50,000 ARS for foreign adults, plus roughly 50,000 ARS for a return bus from El Calafate. Add 30–50 USD if you want the boat tour. Ice trekking pushes the total to 180–260 USD and does not include park entry or transfers.

Can I visit without booking a tour?

Yes. Public buses run twice daily from El Calafate, and the boardwalks are self-guided. You only need advance bookings for Minitrekking, Big Ice, or boat excursions, which sell out in peak season.

How long should I spend at the glacier?

Half a day covers the walkways and a quick look. Allow a full day if you're adding a boat trip, and a second day in El Calafate if you're doing an ice trek — the tours run nine to twelve hours.

When is the best time to see ice calving?

Calving happens year-round, but it is most frequent from December to March when melt is at its peak. Arrive early and stay on the balconies facing Brazo Rico — the loudest collapses usually come from the southern wall.

Is the boardwalk accessible for wheelchairs?

Yes. The main walkway circuit is wheelchair accessible, and the park is one of the few Patagonian glacier sites where visitors with reduced mobility can reach a full frontal view of the ice.
