Royal Caribbean in Alaska: What the Radiance Class Delivers on the Inside Passage

Royal Caribbean's Alaska program is smaller than Princess or Holland America, but the Radiance-class ships are purpose-built for scenic cruising — more glass, better sightlines, and a design that treats the landscape as the main event.

Royal Caribbean in Alaska: What the Radiance Class Delivers on the Inside Passage

Why Now

Royal Caribbean added the Serenade of the Seas to its Alaska rotation in 2025, bringing two Radiance-class ships to the Inside Passage for the first time. The line also expanded its Juneau glacier helicopter program with exclusive access to a new landing zone on the Juneau Icefield.

Key Highlights

  • Radiance-class ships are purpose-built for Alaska with panoramic windows throughout
  • Tracy Arm Fjord access — Radiance-class ships are small enough to navigate the fjord
  • Viking Crown Lounge provides 360-degree views for glacier and wildlife watching
  • FlowRider surf simulator and rock climbing wall set RC apart from HAL and Princess
  • Roundtrip Seattle itineraries — no one-way repositioning logistics
  • Juneau whale watching in Stephens Passage is world-class in June and July

Why Royal Caribbean Chose the Radiance Class for Alaska

Royal Caribbean is famous for its mega-ships — the Oasis class, the Icon class, ships that carry 5,000–7,000 passengers and have roller coasters and waterparks on the top deck. None of those ships go to Alaska.

Alaska requires a different kind of ship. The ports are smaller, the fjords are narrower, and the experience is about the landscape outside the ship, not the amenities inside it. Royal Caribbean understood this when it designed the Radiance class in the late 1990s — ships with more glass, better observation decks, and a design philosophy that treats the scenery as the primary attraction.

The Radiance of the Seas and Serenade of the Seas are the right ships for Alaska. They're not the biggest or the most feature-rich ships in the Royal Caribbean fleet, but they're the best ships for the Inside Passage.

The Radiance-Class Design

The Radiance class has more glass than any other cruise ship class in service. The Viking Crown Lounge at the top of the ship is a 360-degree observation lounge with floor-to-ceiling windows. The Centrum — the central atrium — has glass elevators that look out over the ocean. The Solarium (adults-only pool area) has a retractable glass roof.

On a sea day in Tracy Arm Fjord, with 3,000-foot granite walls on both sides and icebergs in the water, the Radiance class's glass-forward design makes the difference between watching Alaska and being in Alaska.

The Itineraries

Royal Caribbean operates 7-night Inside Passage itineraries from Seattle, calling at Juneau, Skagway, Endicott Arm (Tracy Arm Fjord), and Victoria, BC. The itinerary is similar to Princess and Holland America's standard Alaska program, with one key difference: Royal Caribbean does Tracy Arm Fjord instead of Glacier Bay.

Tracy Arm is narrower and more dramatic than Glacier Bay — the fjord walls are closer, the icebergs are denser, and the twin Sawyer Glaciers at the head of the fjord are visible from the ship's bow. The tradeoff is that Glacier Bay has more wildlife and a park ranger narration that Tracy Arm lacks.

For travelers who have done Glacier Bay on Princess or Holland America, Tracy Arm on Royal Caribbean is a genuinely different experience worth seeking out.

Shore Excursions

Royal Caribbean's Alaska shore excursion program is the most adventure-focused of the major lines. The Juneau helicopter glacier tour includes exclusive access to a new landing zone on the Juneau Icefield — a site that's not available through other lines or independent operators.

The Skagway zip line tour is the most dramatic in Alaska — a series of zip lines through the rainforest above the White Pass, with views of the Lynn Canal. The whale watching tours in Frederick Sound are operated by the same captains who run the best independent tours.

The Bottom Line

Royal Caribbean's Alaska program is smaller than Princess or Holland America's, but the Radiance-class ships are the best-designed vessels for scenic cruising in the mainstream market. The glass-forward design, the Tracy Arm Fjord itinerary, and the adventure shore excursion program make Royal Caribbean the right choice for active travelers who want a smaller ship and a different perspective on the Inside Passage.

If you've done Alaska on Princess, do it again on Royal Caribbean. The Tracy Arm experience is worth the repeat trip.

Frequently Asked Questions

Which Royal Caribbean ships go to Alaska?

Royal Caribbean uses Radiance-class ships for Alaska — specifically Radiance of the Seas and Serenade of the Seas. These are mid-size ships (2,100 passengers) designed with Alaska in mind: large windows throughout, a Viking Crown Lounge with panoramic views, and a size that fits Alaska's smaller ports. Royal Caribbean's mega-ships (Oasis class, Icon class) do not sail Alaska.

How does Royal Caribbean Alaska compare to Princess or Holland America?

Princess and Holland America have deeper Alaska programs with more itinerary variety and more port time. Royal Caribbean's Alaska program is smaller but the ships are excellent for the route. RC's advantage is the onboard activity program — the FlowRider, rock climbing wall, and entertainment options are better than HAL or Princess. If you want the best Alaska experience, HAL wins. If you want a great Alaska experience with better onboard activities, RC is a strong choice.

What is Tracy Arm Fjord and is it worth it?

Tracy Arm Fjord is a 30-mile fjord southeast of Juneau with two active tidewater glaciers — Sawyer Glacier and South Sawyer Glacier. Royal Caribbean's Radiance-class ships are small enough to navigate into the fjord for close-up glacier viewing. It's one of the most spectacular experiences in Alaska cruising. Not all ships can access Tracy Arm — the mega-ships are too large.

When is the best time to cruise Alaska with Royal Caribbean?

Royal Caribbean's Alaska season runs May through September. June and July offer the best weather and longest daylight hours (up to 18 hours of daylight in Juneau in June). May and September offer lower prices and fewer crowds but more variable weather. For wildlife viewing, June and July are peak season for humpback whales in Stephens Passage.

What ports does Royal Caribbean visit in Alaska?

Royal Caribbean's standard 7-night Alaska itinerary visits Juneau, Skagway, and either Ketchikan or Icy Strait Point, with a scenic cruising day in Tracy Arm Fjord or Glacier Bay. The itinerary departs from Seattle and is roundtrip. Some itineraries include Victoria, British Columbia as a final port before returning to Seattle.

The Bottom Line

Royal Caribbean's Alaska program is smaller than Princess or Holland America's, but the Radiance-class ships are the best-designed vessels for scenic cruising in the mainstream market. The glass-forward design, the Tracy Arm Fjord itinerary, and the adventure shore excursion program make Royal Caribbean the right choice for active travelers who want a smaller ship and a different perspective on the Inside Passage. If you've done Alaska on Princess, do it again on Royal Caribbean. The Tracy Arm experience is worth the repeat trip.
