Exploradores Glacier - Ice Trekking (Aysén)

Overview
Exploradores Glacier, in Laguna San Rafael National Park (Aysén Region), offers a memorable experience of ice trekking on the Northern Ice Field. The guided trek with crampons crosses moraines, crevasses, and blue formations. It’s a full-day adventure for well-equipped explorers.
Trekking Information
  • Location: Located in the Exploradores sector of Laguna San Rafael National Park, near Puerto Río Tranquilo.
  • Activity: The excursion consists of trekking over the glacier’s frontal moraine and then on the ice itself, a journey that can last around 10 hours. Along the way, you can see lagoons, caves, and ice formations.
  • Difficulty: It is considered a high-demand trek, although with no steep slopes, due to the long route and rocky “black ice” terrain before reaching clean ice.
  • Guides: Trekking with certified guides and specialized equipment such as crampons and gaiters is mandatory; these are usually provided by the tour agencies.
  • Starting point: Tours depart mainly from Puerto Río Tranquilo, where you’ll find several agencies offering this service.
