Lemaire Channel

FjordsAntarctic Peninsula, Antarctica

August·Closed

Apr–Oct

No expedition ship sails the Antarctic Peninsula from April to October: winter sea ice locks the strait shut and daylight shrinks to roughly three dim hours near midwinter. There is no other way in — the channel simply waits out the dark.

Year-round The cliff-walled Antarctic strait — 'Kodak Alley' — is passable only in the polar summer, November to March, when the ice clears; whales gather most in February and March.

The Lemaire Channel squeezes to barely 600 metres across while the cliffs on either side climb more than 1,000 metres straight out of the sea — a gap narrower than the peaks are tall. Walled off from the open ocean, its water often lies mirror-still, throwing back the glaciers and black rock so cleanly that expedition photographers have called it "Kodak Alley" for generations. The eleven-kilometre strait threads between Booth Island and the mountains of the Antarctic Peninsula's Kyiv Peninsula, along the Graham Land coast. A German expedition sighted the passage in 1873, but no ship risked its ice-choked narrows until February 1898, when Adrien de Gerlache steered the Belgica through and named it for Charles Lemaire — a Belgian who won fame exploring the Congo and never once set eyes on Antarctica. Getting through still depends entirely on the ice. When pack ice jams the channel, ships give up and detour around the seaward side of Booth Island, so a clean run feels like a piece of luck earned rather than booked. The northern entrance is guarded by the twin Una Peaks, and once past them the ship idles between the cliffs at walking pace while everyone crowds the outer decks — this is a scenic cruise, not a shore landing. Passengers scan the floes for crabeater and Weddell seals stretched out in the sun and the black water for the humpback, minke and orca that gather here, most reliably in the settled calm of February and March. Even in the long polar dusk, when the sun barely dips below the peaks, the ice along the shore glows blue and gold for hours.

Worth knowing

Good to know

Watch from the outer decks or the bridge, not ashore — the channel is a scenic-cruising stop with no landing, and captains call it whenever ice and light allow, sometimes before breakfast.
Ships run only from November to March — early season brings the thickest, most dramatic ice and a channel that often blocks; by February and March the ice opens and passage comes easier.
Bring two lenses and keep them ready — a telephoto for seals and whales on the floes, a wide lens for the mirrored cliffs, with the calmest reflections on windless mornings.
Dress in full polar layers before the call comes — the best of the passage can pass in twenty minutes of open deck, and the ship slips through with little warning.
Keep eyes on the ice, not just the sea — seals sleep on the drifting floes and are easy to miss, while whales usually show first as a distant blow against the dark cliffs.

Things to do

1
Ride the outer deck as the ship threads the 600-metre narrows
When the captain calls the passage — often before breakfast, whenever ice and light allow — head for the outer deck or bridge as the ship slows to walking pace between cliffs barely 600 metres apart. You enter past the twin Una Peaks at the northern gate and drift the full eleven kilometres with both shores close enough to fill a wide lens.
2
Come back on deck for the hours-long polar dusk
As the summer sun sinks toward the peaks but never fully drops below them, return to the rail and watch the shore ice hold a slow-shifting glow of blue and amber that lasts hours, not minutes. Grounded bergs the size of buildings sit near the channel edges, their carved faces changing colour as the low light creeps along them.
3
Step ashore at Petermann Island among unbothered Gentoos
Just off the channel, zodiacs run passengers onto the rock at nearby landing sites like Petermann and Jougla, where Gentoo penguins nest right where you set your boots. Crouch low and stay still and the birds carry on within a few metres, treating quiet visitors as part of the scenery.
4
Cruise by zodiac past seals hauled out on the ice
Inflatable zodiacs nose in close to ice floes where crabeater and leopard seals doze in the sun, close enough to hear them breathe. Orcas and humpback whales sometimes appear in the same waters.
5
Walk among thousands of nesting penguins at Cuverville Island
One of the largest Gentoo colonies on the peninsula covers the snow slopes above Cuverville's beach, the noise and smell of tens of thousands of birds rising long before the colony comes into view.
