Visitor Impact

Known impacts The erosion of multiple footpaths through vegetation between the eastern and western ends of the island. Potential impacts Further damage to the vegetation and disturbance of wildlife, particularly southern giant petrels.

Landing Requirements

Ships* Ships carrying 200 or fewer passengers. One ship at a time. Maximum 2 ships per day (midnight to midnight). Visitors No more than 100 visitors ashore at any time, exclusive of expedition guides and leaders. 1 guide per 20 visitors. No visitors ashore between 22:00hrs and 04:00hrs (local time). This is in order to establish a resting period for the wildlife.

Visitor Area

Landing Area Primary: eastern end of the island; landing either on the sand beach to the north, or on the cobbled southern beach. Secondary: northern shore of the western end of the island, with easiest access at high water. Closed Areas Closed Area A: Monitoring sites for chinstrap penguins above and southeast of the eastern landing area. Closed Area B: Central part of the island covered by a very extensive moss carpet (with the exception of the designated walking route) and the northern cliffs where southern giant petrels nest. Closed Area C: Knoll on the southwestern tip of the island where southern giant petrels nest. Guided Walking Areas Only walk through Closed Area B if you can clearly recognise the designated route, which runs over the rocks along the shoreline at the eastern end, and along a narrow gravel stream bed through the vegetation. This route should only be used by closely guided groups of no more than 10 visitors. Only one group should follow the stream bed at a time, taking extreme care not to trample the edges of the vegetation. Free Roaming Areas Visitors can roam freely, but under supervision, anywhere except the closed or guided walking areas.

* A ship is defined as a vessel which carries more than 12 passengers. Barrientos Island (Aitcho Islands) ANTARCTIC TREATY Barrientos Island visitor site guide (Aitcho Islands) 62˚24’S, 59˚47’W - North entrance to English Strait between Robert and Greenwich Islands

Visitor Code of Conduct

Behaviour ashore Walk slowly and carefully. Maintain a precautionary distance of 5 metres from wildlife and give animals the right-of-way. Increase this distance if any change in behaviour is observed. When on the same level as, or higher than, nesting southern giant petrels maintain a precautionary distance of at least 50 metres. Increase this distance if any change in the birds’ behaviour is observed. Be careful near Antarctic fur seals, they may be aggressive. Do not walk on any vegetation. Cautionary notes Stay clear of cliffs and vertical walls and stacks as these are prone to rock falls and slides.
