Summer in El Calafate
Summer is the peak season in El Calafate, offering the best weather to witness the mighty Perito Moreno Glacier. Enjoy long daylight hours, glacier trekking, boat tours on Lago Argentino, and easy access to Los Glaciares National Park from December to February.
El Calafate is the undisputed gateway to one of Patagonia's greatest natural wonders — Perito Moreno Glacier. This small city on the shores of Lago Argentino in Argentina's Santa Cruz province serves as the base for exploring Los Glaciares National Park, a UNESCO World Heritage Site home to 47 glaciers within the Southern Patagonian Ice Field.
Summer, from December through February, is the prime season for visiting El Calafate. Temperatures climb to comfortable highs of 15-18°C, daylight stretches past 10pm with up to 17 hours of light, and all tours and activities operate at full capacity. The famous walkways at Perito Moreno Glacier — where you can watch house-sized chunks of ice calve thunderously into the turquoise waters below — are at their most accessible.
Beyond the glacier, summer opens up a wealth of experiences. Boat tours navigate among the icebergs of Lago Argentino, visiting the Upsala and Spegazzini glaciers. The increasingly popular Big Ice and Mini Trekking excursions take you onto the glacier surface itself. Birdwatchers can spot flamingos at the Laguna Nimez reserve right in town, while adventurous travelers use El Calafate as a base for day trips to El Chaltén and its world-class hiking.
The town itself has evolved into a comfortable tourist hub with excellent restaurants featuring Patagonian lamb, a vibrant Avenida del Libertador lined with shops and cafés, and accommodation options for every budget. Renting a car gives you the freedom to visit the glacier on your own schedule and explore the surrounding steppe landscapes at your own pace.

Activities
Available Activities
Perito Moreno Glacier Walkways
The extensive network of walkways at Perito Moreno Glacier provides stunning viewpoints of the 5km-wide ice wall. Watch and listen for dramatic calving events. The glacier is 80km from El Calafate, easily reached by car or organized tour.
Mini Trekking and Big Ice
Walk on the glacier surface itself with crampons and a guide. Mini Trekking offers a 1.5-hour walk; Big Ice provides a more demanding 3.5-hour experience for those wanting deeper exploration of the ice formations.
Lago Argentino Boat Tours
Full-day boat excursions navigate among icebergs to view Upsala Glacier (one of the largest in South America) and Spegazzini Glacier (the tallest). The Todo Glaciares tour combines multiple glacier visits.
Laguna Nimez Bird Reserve
This wetland reserve on Lago Argentino's shore, just a short walk from downtown, hosts over 80 bird species including Chilean flamingos, black-necked swans, and numerous raptors.
Estancia Day Visits
Visit working Patagonian ranches for gaucho demonstrations, horseback riding, sheep shearing shows, and traditional asado lunches. Estancias like Cristina also combine ranch life with glacier access.
Day Trip to El Chaltén
The 3-hour drive to El Chaltén through scenic steppe landscapes allows for a day of hiking near Mount Fitz Roy before returning. Having a rental car makes this easily feasible.
Not Available This Season
Accommodation
El Calafate has abundant accommodation ranging from budget hostels to luxury hotels with glacier views. Summer is peak season and prices reflect this — book at least 2-3 months ahead for January visits. The Avenida del Libertador area puts you close to restaurants and shops, while properties along the lakeshore offer quieter settings. Estancia stays in the countryside provide unique Patagonian ranch experiences.
Crowds & Tourism
Summer is El Calafate's busiest season, with January being the peak. The glacier walkways can be crowded, especially mid-morning to mid-afternoon. Boat tours and glacier treks book up days or weeks ahead. To avoid the biggest crowds at Perito Moreno, arrive early morning or late afternoon. Despite the visitor numbers, the sheer scale of the glacier means it rarely feels overwhelming.
Pricing
Summer brings the highest prices of the year. Accommodation rates can be 50-100% higher than shoulder season. Glacier tours (Mini Trekking, Big Ice, boat excursions) are significant expenses at $100-300 USD per activity. Car rental and fuel add up on the 160km round trip to the glacier. Restaurant prices in town are tourist-oriented. Budget $150-250 USD per day for a comfortable mid-range trip.
Driving Conditions
Important for car rental travelers
The road from El Calafate to Perito Moreno Glacier (Ruta 11) is fully paved and in excellent condition. The drive to El Chaltén (Ruta 40) is also paved but watch for strong crosswinds on the exposed steppe sections. A standard rental car is sufficient for main routes. Car rental agencies operate in town and at the airport, but book well ahead in summer as demand is very high. Having your own car allows you to visit the glacier at optimal times (early morning or late afternoon) and explore at your own pace.
Packing Essentials
Events & Festivals
Lago Argentino Anniversary
El Calafate celebrates its founding with festivals, live music, cultural events, and community gatherings during the summer season.
Glacier Calving Season
While not a scheduled event, summer warmth increases the frequency of dramatic ice calving at Perito Moreno Glacier. The glacier's natural rupture cycle — when its advancing wall dams the Brazo Rico and eventually bursts — is one of nature's greatest spectacles.

Restaurants and estancias host special Patagonian lamb festivals and gastronomic events featuring regional cuisine, local wines, and artisanal products throughout the summer.

Frequently Asked Questions
How far is Perito Moreno Glacier from El Calafate?
The glacier is approximately 80km (about 1.5 hours by car) from El Calafate via the fully paved Ruta 11. The drive is scenic, passing through steppe and forest landscapes. You can drive yourself with a rental car or join an organized tour.
Do I need to book glacier tours in advance?
Yes, strongly recommended in summer. Mini Trekking and Big Ice experiences often sell out days or weeks ahead. Book these as soon as your travel dates are confirmed. Boat tours should also be reserved in advance, especially in January.
Is it worth renting a car in El Calafate?
Yes, especially if you want flexibility with timing at the glacier (arriving early or staying late is the best strategy to avoid crowds) or plan to visit El Chaltén. Main roads are paved and in good condition. A standard vehicle is fine for the main routes.
How many days should I spend in El Calafate?
A minimum of 2 full days is recommended: one for the Perito Moreno Glacier walkways and one for a boat tour or glacier trek. Three to four days allows you to add a day trip to El Chaltén, visit an estancia, and explore Laguna Nimez without rushing.
What is glacier calving?
Calving is when chunks of ice break off the glacier's face and crash into the lake below. At Perito Moreno, this happens frequently — especially in summer — creating dramatic booming sounds and huge splashes. The walkways provide safe viewing points for this natural spectacle.
Is El Calafate expensive?
El Calafate is one of Patagonia's pricier destinations, especially in summer. Glacier activities, accommodation, and restaurants are the biggest costs. However, walking the glacier boardwalks (after paying the park entrance fee) is the main attraction and represents good value for such a world-class experience.
