Glacier in August: what the park service says
In August 2026, getting to Logan Pass for a long hike meant a shuttle ticket, one per person aged 2 and up, sold only on Recreation.gov or by phone (877-444-6777), never inside the park. Tickets opened about 60 days ahead, with the rest released at 7 p.m. MDT for the next day, and each costs a $1 processing fee. The shuttle did not serve Avalanche Lake or the Trail of the Cedars. Driving up yourself, you could park for three hours at most. Both rules ended on Labor Day.
