# Alaska Inside Passage Small Ship Cruise: Glaciers, Wildlife, and Wilderness

The Alaska Inside Passage is one of the world's great cruise routes — a protected waterway threading between the Pacific Ocean and the rugged coastline of southeastern Alaska and British Columbia. While large cruise ships navigate the main channels, small ship cruises offer something altogether different: the ability to slip into narrow fjords, anchor in remote bays, and experience Alaska's wilderness with genuine intimacy.

Why Choose a Small Ship Cruise

Small expedition ships — typically carrying between 12 and 100 passengers — can access places that larger vessels simply cannot reach. This means anchoring directly in front of calving glaciers, kayaking through kelp forests, and landing on beaches where bears fish for salmon just metres away.

The Advantages of Going Small

Closer glacier access:: Small ships can approach tidewater glaciers far more closely than large cruise ships, which must maintain safe distances

Wildlife encounters:: Quieter engines and smaller wakes disturb wildlife less, leading to better sightings of humpback whales, orcas, sea otters, and Steller sea lions

Remote ports:: Villages like Elfin Cove, Tenakee Springs, and Kake are inaccessible to large ships but perfect for small vessel exploration

Expert naturalists:: Small ship cruises typically include onboard naturalists who lead shore excursions and provide in-depth wildlife and ecology commentary

Flexible itineraries:: Captains can adjust routes based on wildlife sightings and weather, following humpback whales or lingering at a particularly active glacier

Key Highlights of the Inside Passage

Glacier Bay National Park

Glacier Bay is the crown jewel of any Inside Passage itinerary. This UNESCO World Heritage Site contains over 1,000 glaciers, including the spectacular Margerie Glacier — a 21-mile-long river of ice that regularly calves enormous chunks into the bay with thunderous crashes. The park is accessible only by boat or floatplane, making it an exclusive experience for cruise passengers.

The bay's ecology is extraordinary: just 250 years ago, the entire area was buried under a massive glacier. Today, you can witness the full spectrum of ecological succession, from bare rock newly exposed by retreating ice to mature temperate rainforest, all within a single day's sailing.

Tracy Arm Fjord

Tracy Arm is a narrow, 30-mile-long fjord carved by glaciers over millennia. The walls rise nearly 3,000 feet on either side, draped in waterfalls and streaked with mineral colours. At the fjord's head, the twin Sawyer Glaciers calve continuously into a bay choked with icebergs. Harbour seals haul out on ice floes to nurse their pups, and the turquoise meltwater creates an otherworldly palette.

Sitka: Russian Heritage and Wildlife

Sitka was once the capital of Russian America, and its heritage is visible in the onion-domed St. Michael's Cathedral and the Sitka National Historical Park, where totem poles stand among ancient Sitka spruce trees. The town is also home to the Alaska Raptor Center, where injured bald eagles are rehabilitated — a remarkable close-up encounter with these magnificent birds.

Wildlife You Can Expect to See

The Inside Passage is one of North America's richest wildlife corridors. A well-timed small ship cruise offers extraordinary sightings:

Humpback whales:: Feed in the nutrient-rich waters from May through September, often bubble-net feeding in coordinated groups

Orcas:: Both resident fish-eating pods and transient mammal-hunting orcas patrol the passage

Brown and black bears:: Fish for salmon at river mouths during the summer run

Bald eagles:: Nest throughout the region and are a near-constant presence

Sea otters:: Float on their backs in kelp beds, cracking shellfish on their chests

Steller sea lions:: Haul out on rocky outcrops in large, noisy colonies

Puffins and murrelets:: Nest on cliff faces and dive for fish in the open water

Practical Planning Information

Best Time to Cruise

The Inside Passage cruise season runs from May through September. June and July offer the longest daylight hours (up to 18 hours in midsummer), the best weather, and peak wildlife activity. August and September bring salmon runs, which attract bears, eagles, and whales in spectacular concentrations. May is quieter and more affordable, with snow still visible on mountain peaks.

What to Pack

Alaska weather is famously unpredictable. Layering is essential:

Waterproof outer layer:: A quality rain jacket and waterproof trousers are non-negotiable

Warm mid-layers:: Fleece or down insulation for cool mornings and evenings

Rubber boots:: Many ships provide these for wet landings, but check in advance

Binoculars:: Essential for wildlife watching from the deck

Seasickness medication:: The outer coast can be rough; the inner passage is generally calmer

Choosing Your Itinerary

Most small ship Inside Passage cruises run 7 to 14 days, departing from Juneau, Sitka, or Seattle. Longer itineraries allow for more remote exploration and a greater chance of extraordinary wildlife encounters. Look for cruises that include Glacier Bay National Park permits — these are limited and must be arranged well in advance.

Shore Activities and Excursions

Small ship cruises typically include a range of included activities:

Kayaking: through calm coves and alongside glaciers

Zodiac tours: for close-up glacier and wildlife viewing

Hiking: on remote beaches and through old-growth rainforest

Skiff tours: into shallow river mouths to watch bears fishing

Snorkelling: in the cold but remarkably clear waters (dry suits provided)
