Grinnell Glacier

Grinnell Glacier is one of the most famous active glaciers located in the Many Glacier region of Glacier National Park. Accessible via a strenuous hiking trail, visitors are rewarded with dramatic mountain vistas, turquoise glacial lakes, and frequent wildlife sightings. Though shrinking over time, it remains a bucket-list destination for hikers exploring the Montana Rockies.
