Glacier Bay in July: what the park service says

July is the peak of Glacier Bay's visitor season, the park says. Summer highs near sea level run between 50 and 60°F, and rangers lead programs in Bartlett Cove daily, including a guided walk on the Forest Loop Trail from the Glacier Bay Lodge. If your cruise ship enters the park, rangers and Alaska Geographic partners come aboard to narrate the day and give talks.
