Glacier Bay National Park Guide 2026 — Cruises, Kayaking & Whale Watching

Glacier Bay National Park is one of Alaska's most dramatic landscapes — a place where tidewater glaciers calve house-sized chunks of ice into the sea, humpback whales breach against a backdrop of snow-capped peaks, and kayakers paddle through water dotted with icebergs. Located in Southeast Alaska about 65 miles northwest of Juneau, this 3.3-million-acre park draws visitors from around the world who come to witness one of the planet's most active glacial environments.

Whether you're arriving on a cruise ship, booking a day boat tour, or planning a multi-day kayaking expedition, this guide covers everything you need to know about visiting Glacier Bay in 2026.

Getting to Glacier Bay

Glacier Bay National Park is remote — there are no roads leading to it. The gateway town is Gustavus, a small community of about 450 residents on the shores of Icy Passage. The park headquarters and primary visitor facilities are at Bartlett Cove, about 10 miles from Gustavus.

By air: Most visitors fly into Juneau first, then take a small plane to Gustavus. Alaska Airlines operates jet service to Juneau from Anchorage, Seattle, and other cities. From Juneau, several small carriers including Alaska Seaplanes offer daily flights to Gustavus — the flight takes about 30 minutes and offers spectacular aerial views of the Chilkat Range and Lynn Canal.

By ferry: The Alaska Marine Highway operates ferry service from Juneau to Gustavus during the summer season. The trip takes roughly four and a half hours through scenic waterways, though schedules vary by year, so check the AMHS website for 2026 departure times.

Getting around: Once you arrive in Gustavus, the Glacier Bay Lodge operates a shuttle between the airport, town, and Bartlett Cove. Some lodges and outfitters also provide transportation for their guests.

Cruise Ship Visits

For many visitors, a cruise ship is the first and only way they'll experience Glacier Bay — and it's a spectacular introduction. The National Park Service issues a limited number of cruise ship permits each summer, so not every Alaska cruise itinerary includes Glacier Bay. If this park is a priority, confirm your ship has a permit before booking.

Cruise ships typically spend a full day in the bay, traveling up the West Arm toward the massive tidewater glaciers. A National Park Service ranger boards the ship to provide narration and answer questions throughout the day. You'll see the landscape change dramatically as the ship moves deeper into the bay — from dense temperate rainforest near the entrance to barren, recently deglaciated rock near the glacier faces.

The highlight for most passengers is the approach to Margerie Glacier, where ships park for an hour or more while passengers watch (and listen to) the glacier calve. The cracking sounds echo across the water, and when a large piece falls, the splash sends waves radiating outward. Keep your binoculars ready — seals often haul out on floating ice nearby, and mountain goats are sometimes visible on the surrounding cliffs.

Day Boat Tours from Bartlett Cove

If you're staying in Gustavus or at the Glacier Bay Lodge, the full-day boat tour operated by Glacier Bay Lodge is the best way to see the park's glaciers. The tour boat departs Bartlett Cove in the morning and spends eight to nine hours cruising up the bay to the tidewater glaciers.

The experience is more intimate than a cruise ship — the smaller vessel can get closer to the glacier faces, and the onboard naturalist provides detailed commentary about the geology, wildlife, and history of the bay. You'll pass through waters where humpback whales feed during summer, and the captain will slow down or stop when wildlife is spotted.

The boat travels to the upper West Arm, where you'll spend time in front of Margerie Glacier and Grand Pacific Glacier. Lunch is included, and there's an enclosed cabin as well as open deck space for viewing and photography. Dress in warm layers — even in July, temperatures on the water near the glaciers can drop significantly.

Advance reservations are strongly recommended, especially for June and July departures. The tour runs daily during the summer season, typically from late May through early September.

Kayaking in Glacier Bay

Kayaking in Glacier Bay is a bucket-list experience for paddlers. There is nothing quite like gliding silently through water studded with icebergs, hearing the distant rumble of a glacier calving, and camping on shores that were buried under ice just a few decades ago.

Guided trips: Several outfitters offer guided multi-day kayaking expeditions in the park, ranging from three to seven days. These trips are ideal for paddlers who want the experience without the logistical complexity of planning a solo backcountry trip. Guides handle permits, equipment, food, and route planning. Most trips launch from Bartlett Cove or use the day boat for a drop-off deeper in the bay.

Independent kayaking: Experienced paddlers can rent kayaks at Bartlett Cove from Glacier Bay Sea Kayaks and plan their own trips. You'll need to attend a backcountry orientation at the visitor center before heading out. The day boat offers a kayak drop-off service — you can load your kayak on the tour boat, get dropped at a remote point in the bay, and paddle back over several days.

Day paddles: If you're short on time, guided day paddles from Bartlett Cove explore the nearby Beardslee Islands, a calm and sheltered area rich with marine life. You won't reach the glaciers on a day paddle, but the scenery and wildlife are excellent.

Water temperatures in Glacier Bay are dangerously cold year-round. A dry suit or proper immersion gear is essential, and paddlers should have experience with cold-water conditions.

Whale Watching

Glacier Bay is one of the best places in Alaska to see humpback whales. These massive marine mammals migrate to Southeast Alaska's nutrient-rich waters each summer to feed, and Glacier Bay's lower bay and Icy Strait are prime feeding grounds.

Season: Humpback whales are present in Glacier Bay from roughly June through September, with peak activity in July and August.

Bubble net feeding: Glacier Bay is one of the few places in the world where you can witness cooperative bubble net feeding. A group of humpbacks works together — one whale blows a spiral of bubbles to corral schools of herring or krill into a tight ball, then the group lunges upward through the surface with mouths wide open. It's an extraordinary sight, and when it happens near your boat, the scale of these animals is breathtaking.

Whale watching happens naturally on the day boat tour and from cruise ships, but dedicated whale watching charters are also available out of Gustavus and nearby Juneau. The waters around Point Adolphus, just outside the park boundary in Icy Strait, are a particularly reliable area for humpback sightings.

Tidewater Glaciers

Glacier Bay contains some of the most accessible tidewater glaciers in Alaska. These are glaciers that flow from the mountains all the way down to the sea, where they actively calve icebergs into the water.

Margerie Glacier: The park's most visited glacier, Margerie stretches about a mile wide and rises 250 feet above the waterline at its face. It's one of the most active calving glaciers in the park — visitors routinely see and hear chunks of ice breaking off and crashing into the bay.

Grand Pacific Glacier: Located adjacent to Margerie at the head of Tarr Inlet, Grand Pacific is massive but has retreated significantly. It sits right on the U.S.-Canada border and is notable for the dark bands of moraine material visible in its ice.

Johns Hopkins Glacier: Often considered the most dramatic glacier in the park, Johns Hopkins sits at the end of a narrow inlet surrounded by steep mountains. Due to heavy ice conditions and seal pupping activity on the floating ice, the inlet is often closed to vessels within a certain distance of the glacier face during summer. When accessible, the scenery is stunning.

Lamplugh Glacier: A striking blue-tinted glacier on the west side of the bay, Lamplugh is a favorite among photographers for its vivid color.

It's worth understanding that Glacier Bay's glaciers have been in retreat since the late 1700s, when the entire bay was covered by one massive glacier. The bay itself is a product of glacial retreat — a living laboratory for studying how landscapes recover after ice recedes.

Wildlife

Beyond whales, Glacier Bay supports an impressive diversity of wildlife across its marine, coastal, and alpine environments.

• Harbor seals: Hundreds of harbor seals haul out on floating icebergs near the tidewater glaciers to rest and give birth. The Johns Hopkins Inlet is a critical pupping area.
• Sea otters: Look for sea otters floating on their backs in kelp beds, often near the mouth of the bay and in Icy Strait.
• Brown and black bears: Both species inhabit the park. Bears are most commonly seen along the shoreline in the lower bay and around Bartlett Cove, particularly during salmon runs in late summer.
• Mountain goats: Scan the steep rock faces above the glaciers — mountain goats navigate these seemingly impossible cliffs with ease.
• Puffins and seabirds: Tufted and horned puffins nest on rocky islands in the outer bay. The South Marble Islands are a major seabird rookery where thousands of birds — including murres, cormorants, and gulls — nest during summer.
• Steller sea lions: Occasionally spotted hauled out on rocks in the outer bay.

Bring binoculars and a telephoto lens. Wildlife viewing in Glacier Bay often happens at a distance, and the animals are well worth a closer look.

Where to Stay

Glacier Bay Lodge

The Glacier Bay Lodge at Bartlett Cove is the only lodging inside the national park. It's a rustic but comfortable property surrounded by temperate rainforest, with views across Bartlett Cove. The lodge operates seasonally from late May through early September.

Rooms book up early — if you want to stay at the lodge in 2026, reserve as far in advance as possible. The lodge also has a dining room, a small store, and serves as the departure point for day boat tours and kayak rentals.

Gustavus Lodging

The town of Gustavus has several small inns, bed-and-breakfasts, and vacation rentals. Staying in Gustavus gives you more lodging options and a taste of small-town Alaska life. Most properties offer transportation to and from Bartlett Cove.

Camping at Bartlett Cove

The park operates a free campground at Bartlett Cove with walk-in tent sites. It's a beautiful spot in the rainforest with access to a warming shelter, bear-proof food storage, and a fire ring area. No reservations are required — sites are first-come, first-served. All campers must attend a backcountry orientation at the visitor center.

For backcountry camping deeper in the park, you'll need to plan a kayak or boat-supported trip. There are no designated backcountry campsites — you choose your own spot following Leave No Trace principles.

Private Boat Permits

If you're bringing your own vessel into Glacier Bay, you'll need a permit from the National Park Service. The park limits the number of private vessels allowed in the bay at any given time to protect wildlife and the wilderness experience.

Permits are issued on a first-come, first-served basis and can be requested up to 60 days in advance by contacting park headquarters. During peak season (June through August), permits can fill up, so plan ahead. All private boaters must also attend an orientation and follow specific regulations regarding speed, distance from wildlife, and anchoring.

Best Time to Visit

The visitor season at Glacier Bay runs from late May through mid-September, but the sweet spot is June through August.

• June: Long days with up to 18 hours of daylight. Wildflowers bloom at lower elevations. Whale activity is building. This is often the driest month in Southeast Alaska, though rain is always possible.
• July: Peak season. The warmest average temperatures (mid-50s to low 60s Fahrenheit). Humpback whale activity is strong. All services and tours are fully operational. Book everything well in advance.
• August: Still excellent. Whale watching peaks mid-month. Salmon begin running in local streams, drawing bears to the shoreline. Days start getting shorter but remain long by most standards.
• September: Quieter and cooler. Some services begin winding down after Labor Day. Fewer crowds, but weather becomes less predictable.

No matter when you visit, pack layers and quality rain gear. Southeast Alaska is a temperate rainforest — Bartlett Cove receives about 70 inches of rain annually, and weather can shift quickly from sunshine to drizzle and back.

Planning Your Trip

Glacier Bay rewards planning. Between limited lodging, permit requirements, and the logistics of getting to a roadless park, spontaneous visits are difficult. Here's a quick checklist:

• Book flights to Juneau and onward to Gustavus early
• Reserve Glacier Bay Lodge or Gustavus lodging months in advance
• Book day boat tours as soon as your dates are confirmed
• If kayaking, arrange rentals and permits well ahead of time
• If bringing a private boat, request your permit 60 days out
• Pack warm layers, rain gear, binoculars, and a good camera
