Where you’ll visit beyond the Antarctic Circle

Stunningly void of human populations yet rich in sea life and towering with icebergs and mountains, travelling south of the Antarctic Circle is a voyage worth taking.

Marguerite Bay

Expansive and home to countless icebergs, Marguerite Bay is one of the furthest-south destinations you’ll reach along the Antarctic Peninsula. Home to leopard seals and Adelie penguins, the bay is named for the wife of explorer Jean-Baptiste Charcot, who discovered the bay in 1909.

When to go

Expectations in Antarctic Circle by the season

As Antarctic expedition cruises return to the waters south of the Circle, so does the midnight sun. As the days grow longer, the region awakens for a fresh season below 66°S.

Further south than many Antarctic Peninsula sites, the Antarctic Circle’s season begins later, but is well worth the wait. A magical landscape of towering icebergs, breaching humpbacks and marching penguins call these parts home. Late December brings the official midnight sun, while surrounding dates bring ever-present light.

Frequently asked questions about the Antarctic Circle

Below are answers to some of the most common questions.

One of earth’s five major circles of latitude, the Antarctic Circle sits at 66°33 South and is the borderline of the southern polar day and night during summer and winter, respectively. (The other major circles of latitude include the Tropic of Capricorn, Equator, Tropic of Cancer and the Arctic Circle).

It cuts across the northern part of the Antarctic Peninsula, but not all expeditions that venture here will travel south of it.


Yes! Experiencing a true polar day is an incredible experience where the sun doesn’t actually set and remains above the horizon for more than 24 hours. 

It’s also a latitude not visited by all Antarctic cruises, meaning fewer ships in the water and at landing sites.

It’s not just about what’s on land here, but also what’s in the sky. At the beginning and end of the season when there are still hours of night, it’s worth looking up. Down here, there’s no light pollution meaning you’ll have incredible star-gazing opportunities. If you’re lucky, you may be able to see the Southern Lights (Aurora Australis) too, but it’s not as likely during the summer months.


The only year-round populations in the Antarctic Circle are on research stations. There’s about 70 on the continent that remain in use year-round. Rothera Research Station on Adelaide Island and San Martín Base on Barry Island are two examples.


If you’re heading into the Antarctic Circle to visit destinations along the Antarctic Peninsula, then yes, you do. The notorious two-day voyage is still the shortest way to reach the peninsula. 

Cruises to the Ross Sea typically start in Tasmania or New Zealand and don’t cross the Drake Passage. Seas on both voyages can be unpredictable, so it’s best not to opt for one over the other in hopes of better conditions.
