Deception Island is the ring-shaped caldera of an active volcano located in the South Shetland Islands off the Antarctic Peninsula. Its collapsed center forms Port Foster, a large, protected natural harbor accessible through a narrow gap called Neptune’s Bellows. Despite being heavily covered by permanent glaciers, the island features geothermal activity that warms its black volcanic sands and waters. Once a bustling hub for sealing, whaling, and scientific research stations—many damaged by eruptions in the late 20th century—it is now a popular Antarctic destination. The image above, taken by a satellite, reveals the unique shape of this island.
Our captain expertly sailed us into the center of the island, where we launched Zodiacs for our last on-shore adventure. Once on terra firma, we made a relatively short but moderately steep hike up to a viewpoint that offered sweeping views of the area. The climb was made more difficult by very high winds carrying sleet horizontally. Anyone with exposed skin would immediately understand how sandblasting metal is a good way to remove rust. One hour of discomfort was totally worth the photos I came back with.
