Guia completo de Perito Moreno Glacier →

Perito Moreno Glacier is arguably the most famous glaciar in the world, and for good reason. This 250-square-kilometer river of ice advances roughly 2 meters per day into Lago Argentino, creating a 5-kilometer-wide, 60-meter-high wall of fractured blue ice that regularly produces thunderous calving events. Unlike most glaciers worldwide, Perito Moreno is in a state of dynamic equilibrium — it is neither retreating nor growing significantly — making it a rare exception to global glaciar decline.

Located within Los Glaciares Parque Nacional, a UNESCO World Heritage Site in Santa Cruz province, the glaciar is accessed from the tourist city of El Calafate, 80km away. Verão from dezembro a fevereiro offers the best conditions for visiting: temperatures are the mildest of the year (14-18°C), daylight extends past 10pm, and the warming temperatures increase the frequency of spectacular calving events as thermal stress fractures the ice front.

The glaciar experience operates on multiple levels. The extensive walkway system provides a series of elevated viewpoints facing the ice wall — you can spend hours watching and listening for the rifle-crack sounds that precede a calving event. For those wanting to set foot on the ice, Mini Trekking and Big Ice excursions strap crampons on participants and lead guided walks on the glaciar surface, weaving between crevasses and seracs of stunning blue. Boat tours approach the ice wall from below, adding yet another perspective.

Verão is the busiest season but also the most rewarding. The combination of good weather, full tour availability, and the glaciar's increased verão activity makes this the optimal time for what many travelers describe as the single most impressive natural sight they've ever witnessed.

Resumo do Clima

Max Media

16°C

Min Media

5°C

Precipitacao

Relatively low in verão with about 20-30mm per month. Brief showers are possible. The glaciar area has its own microclimate and can be cloudier than El Calafate.

Vento

Strong and persistent — the glaciar funnels cold air off the ice field, creating localized winds that can be biting. The walkways are exposed to this glaciar wind.

Luz do Dia

Exceptionally long with 16-17 horas de luz do dia, allowing visits at various times of day for different lighting conditions and calving opportunities.

At the glaciar, verão temperatures feel 5-10°C cooler than in El Calafate due to the ice mass and wind. A sunny day in El Calafate might feel cold at the glaciar face. Layers are essential. The microclimate can produce localized clouds and mist even when skies are clear elsewhere. Morning visits often have calmer conditions; afternoon brings stronger wind.

Atividades

Atividades Disponiveis

Glacier Walkways

The park's extensive metal walkway system faces the glaciar's northern face, providing multiple viewpoints at different heights and angles. Spend hours watching for calving events — the thunderous crash of ice into the lake is unforgettable.

Mini Trekking

A guided 1.5-hour walk on the glaciar surface with crampons. After a boat crossing and forest walk, you explore blue ice formations, small lagoons, and crevasses. Suitable for moderately fit people aged 10-65.

Big Ice

A more demanding 3.5-hour glaciar walk penetrating deeper into the ice formations. Encounter massive seracs, deep crevasses, and extraordinary blue ice caves. For fit, adventurous travelers aged 18-50.

Safari Náutico Boat Tour

A 1-hour boat ride approaches the glaciar's southern face from the water, providing a dramatic perspective of the 60-meter ice wall towering overhead. Often combined with walkway visit.

Full-Day Glacier Combination

Combine walkway viewing with either a boat tour or a glaciar trek for a comprehensive experience. The different perspectives — from above, from the water, and from the ice itself — create a complete understanding of the glaciar's scale.

Hospedagem

El Calafate (80km away) is the hospedagem base, ranging from hostels to luxury hotels. There is no hospedagem at the glaciar itself. The Glaciar Perito Moreno sector of the park has no overnight facilities for visitors. See the El Calafate verão guide for detailed hospedagem information.

Lotacao e Turismo

Verão is alta temporada and the glaciar walkways can be busy, particularly between 11am and 3pm. Mini Trekking and Big Ice book out days or weeks ahead. To experience the glaciar with fewer people: arrive when the park opens (8am) or visit late afternoon (after 4pm, possible with long verão daylight). Early morning also offers calmer wind conditions.

Precos

National park entrance fee is approximately $25-35 USD for foreigners. Mini Trekking costs around $150-200 USD. Big Ice approximately $200-300 USD. Safari Náutico boat tour about $30-50 USD. The drive from El Calafate (combustível for 160km round trip) or tour transport adds to costs. Despite the expenses, the experience is universally rated as exceptional value for a once-in-a-lifetime sight.

Importante para viajantes com carro alugado

The 80km road from El Calafate to the glaciar (Ruta Provincial 11) is fully paved, scenic, and well-maintained. The drive takes approximately 1.5 hours and passes through forest with periodic lake views. A standard carro alugado handles it easily.

Camera with fully charged batteries (cold drains them)
Extra camera battery kept warm in pocket
Binoculars for viewing calving from distance
Water and snacks

Eventos e Festivais

Verão Calving Season

Warmer verão temperatures increase thermal stress on the glaciar face, resulting in more frequent calving events. While calving occurs year-round, verão typically offers the most dramatic and frequent ice collapses.

Glacier Rupture Cycle

Perito Moreno periodically advances far enough to dam the Brazo Rico arm of Lago Argentino. Water pressure eventually causes a dramatic rupture. This multi-year cycle produces one of nature's greatest spectacles when it occurs — though timing is unpredictable.

Pros e Contras

Pros

  • Best weather of the year for comfortable glaciar viewing.
  • Increased calving frequency due to verão thermal stress.
  • All glaciar activities and tours operating at full capacity.
  • 17 horas de luz do dia for flexible visit timing.
  • Multiple perspectives: walkways, boat, and on-ice experiences.
  • One of the world's only stable/advancing glaciers — a rare sight.

Contras

  • Peak season means highest prices and largest crowds.
  • Mini Trekking and Big Ice book out well in advance.
  • Strong, cold glaciar winds even on warm verão days.
  • Mid-day crowds at the walkways can be dense.
  • 80km drive from El Calafate required each way.

Perguntas Frequentes

How often does the glaciar calve?

Small calving events happen throughout the day — the cracking sounds are constant. Larger, dramatic calves where car-sized or house-sized chunks break off happen several times per day in verão. There's no schedule — patience at the walkways is rewarded. Most visitors witness at least one significant calving event.

Which is better — Mini Trekking or Big Ice?

Mini Trekking (1.5 hours on ice, ages 10-65) gives a great introduction to walking on a glaciar. Big Ice (3.5 hours on ice, ages 18-50) goes deeper with more dramatic formations. If you're fit and adventurous, Big Ice is the more immersive experience. Both are excellent.

Can I visit the glaciar independently?

Yes, the walkways are self-guided after paying the park entrance fee. You can drive yourself and spend as much time as you want. Only the glaciar trekking and boat tours require organized bookings. Having a carro alugado gives you the freedom to arrive early or stay late.

Why is Perito Moreno special compared to other glaciers?

It's one of the few glaciers in the world that is advancing rather than retreating, making it exceptionally dynamic. The 5km-wide ice wall calves directly into a lake with walkways just 500 meters away — the proximity and scale are unmatched. The thunderous calving events create an intensely visceral experience.

How cold is it at the glaciar in verão?

Even when El Calafate is a pleasant 17°C, the glaciar area feels significantly colder — typically 5-10°C with wind chill. The ice mass generates its own cold air flow. Dress as if for conditions 10 degrees cooler than the forecast for El Calafate.
