Visitor code of conduct

BEHAVIOUR ASHORE

All visits are to be conducted in accordance with the General Guidelines for Visitors to the Antarctic.
Be careful around and avoid walking on the area of sealing remains. Do not move any artefacts.
Do not move any whale bones.
Do not move or sit on the remains of the sealing trypot.
Do not walk through the remains of the the sealers hut. The foundation of this hut is easily overlooked. It is located about 10m south-east of the trypot (at 62°32'01.3”S, 059°46'53.2”W)
In this area it is advisable to maintain gaps between groups of visitors to avoid disrupting penguin movement.
Skuas regularly nest on the spit. When sitting on eggs, the birds blend in with the boulders and are easily overlooked. Avoid disturbing their nests.
When moving across the plain between the south-western shore and penguin colonies monitor nearby wildlife movements and remember to give wildlife right-of-way.
