Is it a campground?
There's a very short handicap accessible plank trail called Trail of the Cedars at this pull-off and a few mile in and out hike to Avalanche Lake. No solitude, but great easy hike for people of all ages.
GLACIER SUMMER ADVICE: All campsites in the park can and do fill up. Check this website to see what is available and what time the campsites are filling up each day (Hint: sometimes it is 8 a.m.) http://home.nps.gov/applications/glac/cgstatus/cgstatus.cfm
