Experience Glacier Exploradores, where you can walk on a living glacier fed by the Northern Patagonian Ice Field. Located in Chile's Aysen region near Puerto Rio Tranquilo, this accessible glacier trek offers ice caves, crevasses, and panoramic views without the crowds of more famous glaciers.
Glacier Exploradores is one of Patagonia's most thrilling yet accessible glacial experiences. Descending from the Northern Patagonian Ice Field, the glacier spills into a forested valley west of Puerto Rio Tranquilo, reachable by a spectacular 52 km drive through the Valle Exploradores. Unlike the distant viewing platforms at Perito Moreno or the expensive boat approaches to other glaciers, Exploradores lets you step directly onto the ice with crampons, walking through a landscape of blue crevasses, ice caves, seracs, and meltwater channels that changes with every season.
The journey to the glacier is itself a highlight. The gravel road through Valle Exploradores winds through dense temperate rainforest, crosses rushing glacial rivers, and passes beneath hanging glaciers visible from the road. The final approach involves a short hike through forest and over glacial moraine before reaching the ice edge, where guides fit crampons and lead groups onto the glacier surface. The experience is visceral: the crunch of crampons on blue ice, the deep turquoise of meltwater pools, and the creaking, groaning sounds of a glacier in motion.
For travelers driving the Carretera Austral with a rental car, the detour to Glacier Exploradores is one of the most rewarding side trips available. Based in Puerto Rio Tranquilo, the same town used as a launching point for the famous Marble Caves, you can combine both experiences within a day or two, creating a comprehensive exploration of ice and stone that showcases the extraordinary diversity of Chile's Aysen region.

Strap on crampons and walk directly on the glacier surface with experienced guides. Routes vary by season and glacier conditions, but typically include walking through ice corridors, peering into crevasses, exploring shallow ice caves, and drinking glacial meltwater directly from pools on the ice. Treks range from 2 to 5 hours on the ice.
The 52 km drive from Puerto Rio Tranquilo through Valle Exploradores is among the most scenic on the entire Carretera Austral. The gravel road passes through virgin rainforest, crosses glacial rivers on wooden bridges, and offers viewpoints of hanging glaciers and the distant ice field. Allow extra time for stops and photography.
The glacier's surface features ever-changing ice formations including shallow caves, moulins (vertical shafts), seracs (ice towers), and pools of intensely blue meltwater. Guides lead you to the most impressive features of the day, which shift as the glacier moves and melts. The blue color intensity of the compressed glacial ice is remarkable.
From elevated points on the glacier, you can see the vast expanse of the Northern Patagonian Ice Field stretching to the horizon. This is one of the largest non-polar ice masses on Earth, and standing on one of its outlet glaciers provides a humbling perspective on the scale of Patagonian ice.
Puerto Rio Tranquilo serves as the base for both Glacier Exploradores and the world-famous Marble Caves boat tour. Combining both experiences creates a powerful two-day itinerary showcasing the region's geological diversity, from sculpted marble to living ice, all accessible from a single small town.
Before reaching the ice, you hike approximately 45 minutes through Valdivian temperate rainforest and across glacial moraine. The contrast between the lush green forest and the stark white-blue glacier is dramatic. The trail passes interpretive signs about glaciology and the local ecosystem.
December - February
Mild (10-18°C) with the longest days and generally the best weather for glacier trekking. Rain is still common. The glacier surface is most accessible and ice formations are most dramatic during melt season.
Moderate crowds
Book glacier trek tours at least 2-3 days in advance during peak summer. Morning departures generally have better weather before afternoon clouds build. This is the best season for the longer 5-hour ice treks.
March - May
Cooling (5-12°C) with increasing rain and shorter days. Early March is still excellent for glacier trekking with fewer people. By April, conditions become challenging and some operators close.
Low crowds
March offers the sweet spot of autumn colors in the forest combined with good glacier access and far fewer visitors. Book in advance as operators may reduce departure frequency.
June - August
Cold (0-6°C) with heavy rain and snow. The access road through Valle Exploradores may be closed or dangerous. Glacier trek operators do not operate.
Low crowds
The glacier is not accessible for tourism in winter. The Valle Exploradores road can be impassable due to snow and ice. Plan your visit for the warmer months.

Wear sturdy, waterproof hiking boots with stiff soles (flexible-soled shoes cannot accept crampons). Dress in moisture-wicking layers with a warm mid-layer and waterproof/windproof outer shell. Bring gloves, a warm hat, and sunglasses. Sunscreen is essential even on cloudy days due to reflection off the ice. Avoid cotton, which stays wet and cold.
The road is safe but demands attention. It is gravel throughout, narrow in sections, and includes some steep grades and stream crossings. A high-clearance vehicle is recommended. Drive slowly, use headlights for visibility, and check conditions locally before departing. The scenery is so dramatic that you will want to stop frequently.
They offer very different experiences. Perito Moreno is viewed primarily from boardwalks or a boat, with optional mini-treks on the ice surface. Exploradores offers a more intimate, adventurous on-ice experience with fewer visitors and longer time on the glacier. Perito Moreno is more famous and accessible; Exploradores is more raw and immersive.
It is technically possible but exhausting and not recommended. The glacier requires a full morning-to-afternoon commitment including the 3-4 hour round-trip drive and 4-6 hours for the trek. The Marble Caves boat tour is a separate 2-3 hour activity. Spread these over two days for a much more enjoyable experience.
