Exploring the U.S. East Coast—Expedition Style

Starting spring 2022, National Geographic Sea Lion embarks on a series of brand-new itineraries unlike any others in the region. Join us to explore the Eastern Seaboard in a way few ever will.

Icebergs: Nature's Sculpture Garden

The towering icebergs in Alaska's LeConte Bay are absolutely awe-inspiring. Zodiac cruising among the many-hued bergs is like visiting a natural art museum.

The Amazing Natural Allure of California's Channel Islands

One of the most biodiverse places on Earth is also one of America’s least visited national parks.

Wildlife & Natural Wonders in the Pacific Northwest

From killer whales in the waters around the San Juan Islands to bighorn sheep on the sheer rock faces of Hells Canyon, the wildlife and scenery of the Pacific Northwest are vastly varied.

Alaska

Each summer thousands of people flock to Alaska to experience its legendary wildness, but only a relative few will actually explore it.

New! Discover the U.S. East Coast

There’s an American East Coast that few know exists and even fewer will ever experience. Starting fall of 2022, National Geographic Sea Lion will embark on a series of all-new itineraries unlike any in the region.

Exploring California

When you look at California through an explorer's lens, there’s so much to discover—an exciting prospect for ‘left coast’ lovers, and proof that far-reaching travel is closer than you think.

Pacific Northwest

We have been exploring here for decades, and our fleet of four ideally-sized ships will convey you to beautiful places where larger ships simply cannot go.
