Huckleberry Lookout, is located on the West-North section of the Park.  Take the road towards PoleBridge.  The hike is about 6 miles each way with quite an Elevation Gain.  It doesn't seem like your even in the park.  Many of the Major Higher peaks are visible from this lofty View Point.  The entirety of Glacier NP from north to south is laid out in front of you, one can view all the way to the lesser peaks at the South of the Park, all they Way up into Waterton NP and Canada.
