⚠️Wilderness & Weather SafetyCold, wet, remote
🌧️ NPS frames this park as "very dynamic, and can be unforgiving to the ill-prepared." Persistent rain, overcast skies, and cool conditions (45–65°F summer highs, near-freezing nights) make hypothermia a real risk. Tides swing up to 25 feet in 6 hours, and both black and brown bears — plus moose, which NPS calls "potentially extremely dangerous" — share the park. Giardia is present in water sources and paralytic shellfish poisoning is a risk from mussels and clams. NPS safety info ↗

🧊Tidewater Glaciers65-mile retreat
Glaciers of Tarr Inlet3
Margerie GlacierThe most-visited glacier — actively calving, ~21 miles long, primary destination for tour boats and cruise ships
Grand Pacific GlacierThe original glacier that carved the bay; now largely grounded with a less dramatic ice front than in the past
Johns Hopkins GlacierThe most actively calving of the three, with dramatic submarine calving of basal icebergs
Historical Retreatcontext
Late 1700sCaptain Vancouver's 1794 survey found the bay was essentially ice-choked — "a small five-mile indent in a gigantic glacier"
TodayThe ice has retreated roughly 65 miles — one of the fastest documented glacial retreats on record; NPS notes 11% less glacial ice than in the 1950s
Johns Hopkins Inlet Closureseasonal
May 1 – June 30Closed to all vessels annually to protect a major harbor seal pupping and mating aggregation
🚢Cruise Ships & Tour Boats100+ year tradition
🛳️ NPS: "For over 100 years, most visitors to Glacier Bay enjoy the amazing landscape of Glacier Bay from the deck of large cruise ships." NPS manages the number of vessels permitted in the bay each day. The park concessioner, Glacier Bay Lodge, operates the daily day-boat tour with a Park Ranger Naturalist aboard — NPS calls it the next most popular activity after cruise ships. NPS cruising info ↗
