Perito Moreno Glacier is one of the most iconic natural wonders of Patagonia and a must-see for anyone exploring southern Argentina. Nestled within the pristine Los Glaciares National Park in the province of Santa Cruz, this colossal ice formation captivates travelers with its sheer size, stunning blue hues, and the thunderous cracking of ice as it calves into the waters of Lake Argentino.
Where Is the Perito Moreno Glacier Located?
The glacier is situated in the southern sector of Los Glaciares National Park, approximately 80 kilometers (about 50 miles) west of the town of El Calafate, the main access point for visitors. It faces the Magallanes Peninsula and extends into the Patagonian Andes, which also mark the border between Argentina and Chile. Nearby natural highlights include Mount Fitz Roy and the trekking capital of Argentina, El Chaltén.
Quick Facts About Perito Moreno Glacier
- Height: Approximately 70 meters (230 feet) above the lake surface
- Depth: About 170 meters (558 feet) below the waterline
- Length: Roughly 30 kilometers (18.6 miles)
- Surface Area: Around 200 square kilometers (77 square miles), roughly the same size as Buenos Aires
- Growth Rate: Advances 1 to 2 meters per day, making it one of the few glaciers worldwide that is still growing
What Makes Perito Moreno Unique?
Unlike most glaciers across the globe that are retreating due to climate change, the Perito Moreno Glacier is surprisingly stable and even advancing. This anomaly is partly why it’s such a popular destination. Its dynamic movement creates natural ice dams within Lake Argentino, eventually leading to dramatic ice ruptures — a phenomenon that draws crowds from all over the world.
Top Things to Do at the Perito Moreno Glacier
1. Explore the Walkways
The primary attraction is walking along the network of elevated walkways offering stunning views of the glacier’s north and south faces. These trails are color-coded and vary in length and difficulty:
| Trail | Difficulty | Duration |
|---|---|---|
| Central Trail (Yellow) | Easy | 1 hour |
| Lower Circuit (Red) | Challenging | 1 hour 15 minutes |
| Coastal Trail (Blue) | Moderate | 2.5 hours |
From these vantage points, you may be lucky enough to witness smaller ice calvings that echo like thunder through the valley.
2. Boat Ride Along the Glacier Face
For a more immersive experience, consider taking a boat tour that gets you close to the towering ice walls. Departing from Puerto Bajo las Sombras, the hour-long trip crosses the Rico Arm of Lake Argentino. Along the way, a guide provides fascinating insights about the glacier’s formation, behavior, and history.
3. Ice Trekking Adventure
One of the most exhilarating activities is walking directly on the glacier itself. Known as the Minitrekking experience, this guided tour begins with a hike through a scenic forest trail before reaching the edge of the ice. After fitting your crampons, you’ll step onto the glacier and spend about 90 minutes exploring crevasses, blue lagoons, and ice formations.
There is also a more intense version called Big Ice, which involves several hours of glacier exploration and is suitable for those in excellent physical condition.
4. Visit the Glacier Interpretation Center
Located near the walkways, this center provides educational exhibits about glaciology, climate change, and the history of the region. It’s a great place to deepen your understanding of this natural marvel before or after your outdoor adventures.
When Is the Best Time to Visit the Perito Moreno Glacier?
Patagonia’s weather is famously unpredictable, but each season offers a unique experience:
- December to February (Summer): Warmest and most popular months, with longer daylight hours and higher prices
- March to May (Fall): Fewer crowds, beautiful foliage, and moderate temperatures
- June to August (Winter): Cold and quieter, perfect for solitude and unique snowy landscapes
- September to November (Spring): A pleasant time with blooming flora and improving weather conditions
Though summer is ideal for weather and glacier viewing, visiting in the off-season can mean lower costs and a more tranquil experience. No matter the time of year, be sure to pack layers, waterproof gear, and a windbreaker — Patagonia is known for its sudden weather shifts.
