Perito Moreno Glacier Trail

Guided glacier trekking on the Perito Moreno Glacier is a specialized activity within Los Glaciares National Park. The glacier, covering approximately 250 square kilometers, is one of the few advancing ice masses in the Patagonian Andes. Access to the ice surface is strictly regulated and conducted via two primary excursion formats: the 'Minitrekking' (introductory) and the 'Big Ice' (extended exploration). Participants navigate a dynamic landscape of crevasses, moulins, and ice ridges using technical equipment under professional supervision. The experience provides a direct perspective on glacial movement and the hydrological processes of the Southern Patagonian Ice Field.

Sierra Negra Volcano Hike Galápagos. Sierra Negra is a massive shield volcano on the southern end of Isabela Island, Ecuador, within the Galápagos National Park. As an Official Marked Trail, the 16km guided tour from Puerto Villamil transitions from humid highlands into one of the largest calderas on Earth. The floor of the 10km-wide Sierra Negra caldera is covered in black basaltic lava flows. Beyond the main rim, the trail continues to the Volcán Chico lava fields, where geothermal activity has created a landscape of colorful sulfur deposits and parasitic vents.
