Glacier hiking is an outdoor activity that involves walking on a glacier, which is a large mass of ice that forms from compacted snow over many years. Hikers typically use special gear, such as crampons and ice axes, to navigate the icy terrain safely. Guided tours are common, as experienced guides help ensure safety and provide information about the glacier's features. This activity allows participants to explore stunning landscapes, including deep crevasses, ice formations, and unique geological features. Glacier hiking is popular in regions with glaciers, such as Iceland, Alaska, and the Swiss Alps, attracting adventure seekers and nature lovers alike.
