Island Antarctic island in the South Shetland Islands

Robert Island, in the South Shetland Islands off Antarctica’s peninsula, offers rugged coastline, seabird and seal colonies and occasional landings by research teams and expedition cruises.

Main image

Robert Island is a small island in the South Shetland Islands, Antarctica, located north of the Antarctic Peninsula. The island is uninhabited and characterised by rocky shores and polar climate conditions.

The island was charted and visited by early 19th-century sealers and later by scientific expeditions, and today any visits are typically by research teams or expedition cruise ships under the regulations of the Antarctic Treaty. There are no permanent facilities on the island and landing is weather-dependent.

The island lies within the archipelago of the South Shetland Islands, a common region for Antarctic research and visitor itineraries that operate from the northern Antarctic Peninsula.

  • Status and governance: Uninhabited island within the Antarctic region and subject to the Antarctic Treaty System, with no permanent settlement or infrastructure.

How to Get to Robert, isla #

Robert Island (Antarctica) is accessible only as part of Antarctic expeditions. Typical departures are by ice‑strengthened expedition ship from Ushuaia (Argentina) or Punta Arenas (Chile); landings are made from the ship by inflatable boats (zodiacs). There are no scheduled commercial air services-access requires an organised expedition or research vessel.

Tips for Visiting Robert, isla #

  • If you plan any visit that includes Robert Island, go in the austral summer (roughly December-February) when Antarctica cruises operate and landings are possible.
  • Travel only with an experienced Antarctic operator (IAATO members)-there are no facilities on small Antarctic islands and landings are by Zodiac, usually attempted in calmer morning conditions.
  • Expect no services and strict biosecurity rules; brief landings focus on wildlife and scenery rather than longer hikes, so plan logistics with your expedition leader.
