Pier Intelligence
⚠️ THIS IS NOT A PORT STOP — It's a Full-Day Scenic Cruise
Critical:
Your ship does NOT dock. You do NOT disembark. There is no pier, no terminal, no tender. Ships spend 8-10 hours cruising inside a national park, then exit the way they came in.
Key Insight:
The NPS limits access to a maximum of 2 cruise ships per day (153 total visits Jun-Aug). Only 6 cruise lines hold concession contracts: Holland America, Princess, Norwegian, Cunard, Seabourn, Viking, and Royal Caribbean.
Docking Variables
-
No dock exists.
Ships cruise, not moor
-
NPS rangers board via ladder at park entry
-
Off-boat activity from cruise ships is prohibited by federal regulation
-
Ship rotates 360° at glacier face for all-side views

Top 6 Viewing Highlights
🧊
Margerie Glacier
The main event. 21-mile-long tidewater glacier with a vivid blue-white face towering 250ft above the waterline. Most active calving glacier in the park. Ship parks here ~1 hour, rotating 360° so both sides get views. Listen for "white thunder."

Grand Pacific Glacier
Adjacent to Margerie at Tarr Inlet's head, 2 miles wide and extending into Canada. Covered in dark moraine—looks like rock, but it's glacier. Once blanketed the entire bay. Currently receding. Easy to miss if you don't know to look.

Icy Strait (Entry Waters)
One of the highest humpback whale concentrations in Southeast Alaska. Rich feeding grounds. Watch for spouts, breaches, and bubble-net feeding as the ship enters and exits the bay. Peak whale activity: June-July.

South Marble Island
A birder's paradise. Tufted and horned puffins, black oystercatchers, common murres, kittiwakes, and pelagic cormorants nest on rocky cliffs. Steller sea lions haul out on rocks below. Ship slows here—don't be inside!

Striking blue-ice glacier at Johns Hopkins Inlet mouth. 20 miles long, 165ft face. Ship often slows here before or after the main glacier stop. Humpback whales frequently spotted near this glacier. Look for the vivid blue cavern at its base.
