Mendenhall Glacier and Whale Watching: Dolphin Jet Boat Tours Since 1994

Water propulsion instead of propellers

Dolphin Jet Boat Tours specifically markets its fleet as mammal-friendly: jet boats use water propulsion rather than traditional propellers, which cuts the underwater noise that disturbs whale behavior. The company has been operating in Juneau since 1994 — the original whale-watching company in town, family-owned and hiring locally — and that tenure shows in how the boats are run. Captains Perry, Sam, Jay and Simon have decades of experience knowing where humpbacks and orcas feed, rest and travel in Juneau's waters, backed up by radio communication with other boats on the water.

What the sighting record looks like

The whale-watching results in recent reviews are strong. One August 2025 traveller saw humpback whales, a sea otter, harbor seals, sea lions, Dall porpoises and bald eagles on the same tour. Richard H. in July 2025: "Sam and Simon were great captains and got us to areas where we saw humpback activity and then to another where we saw orca activity.

We saw so much — that even Sam and Simon were surprised." Gene A. in May 2026 saw several whales and "the unique opportunity of seeing one very close." Sightings still depend on conditions — the naturalists brief you on what's realistic for the day — but in peak season, June through September, humpbacks are consistent and orcas turn up more often than the odds suggest.

The crew gets named, repeatedly

The naturalists draw specific praise across months of reviews. Nia is the most-mentioned name — "full of knowledge and enthusiasm, she loves her job" — and Rio gets similar credit. The bus drivers earn reviews of their own: Charlie once stopped so a sick passenger could buy medicine at a store, and Terracita, driving in August 2025, let participants choose their own duration at the glacier.

When an operator's front-line staff show up by name in review after review, that's usually the difference between a transport service and a tour.

2 hours whale watching from Auke Bay Harbor

After a bus ride from downtown to Auke Bay Harbor — with driver commentary on Juneau along the way — you board the jet boat. The captain works local knowledge and the boat-to-boat radio to find whale activity. The enclosed cabin has seating and windows for rainy days, and an outdoor deck is open for open-air viewing when something surfaces.

Snack bag, hot chocolate and coffee are handed out on board — a real snack bag, as one review puts it, not just granola bars.

15 minutes at the glacier viewpoint

After the whales, the bus takes you inland to the Mendenhall Glacier viewpoint for a 15-minute photo stop — step out, take the picture of the glacier face, back on the bus. This tour is built around the whales, and the glacier is the bonus. If you want real glacier time — Photo Point, the salmon-stream boardwalk, the falls trail — the extended whale-guarantee version is the same operator's combo with that time built in.

• Mammal-friendly jet boat — 2 hours on the water
• Snack bag + hot chocolate and coffee on the boat
• Bus transfer from the cruise terminal to Auke Bay Harbor and the glacier
• 15-minute photo stop at the Mendenhall Glacier viewpoint

The fine print worth reading

Booking confirmation is received within 48 hours, not instantly — if your cruise schedule is tight, book early enough to have the confirmation in hand. Whale sightings depend on conditions, and the naturalists tell you what to expect on the day. The tour is not wheelchair accessible but is stroller accessible; infants ride on laps; the maximum group is 60 travellers.

Cancellation is free up to 24 hours before the start with a full refund. If you'd rather skip the boat entirely and just do the glacier cheaply, the trolley-only option exists on the full list of Mendenhall Glacier tours.
