Mount Indefatigable is a 2,667-metre mountain located in Peter Lougheed Provincial Park in the Canadian Rockies of Alberta, Canada. Named after a British battlecruiser that sank during World War I, this peak offers stunning views and challenging hiking opportunities. The first ascent was made in 1901, and although the popular trail to the summit has been decommissioned to protect grizzly bear habitat, adventurous hikers can still explore its rugged beauty. With its rocky terrain and subarctic climate, Mount Indefatigable is a must-see for outdoor enthusiasts looking for a memorable mountain adventure in the heart of the Rockies.
