Getting There & Around
How to Get to Gamma Island
There is no regular transport; visits are made only as part of Antarctic expedition cruises that depart from Ushuaia (Argentina) or Punta Arenas (Chile). Landings are by zodiac and depend entirely on sea and ice conditions; passengers usually embark on multi-day voyages that include the South Shetland Islands and the Antarctic Peninsula.
Tips for Visiting Gamma Island
- Travel to Antarctica only with an IAATO-certified operator and confirm planned landings - Gamma Island is remote and landing depends on sea and ice conditions.
- Bring windproof outer layers and eye protection: Antarctic islands are exposed, and wind-driven spray and glare can be brutal even in summer.
- Watch for wildlife from the zodiac - landings may be brief and protected; never approach or feed seals or penguins.
