Know Before You Go
The penguins are mostly active after nightfall. There are no available restrooms and temperatures drop significantly on the pier after sundown.
Do not feed, touch, or handle them, and move if they start coming toward you. Don’t crowd them if they happen to be away from the protective fences, and stay off the rocks that lead down to the water. Don't use flash photography or white flashlights (red filtered illumination is alright) to view or photograph the penguins. It can sicken or injure the penguins, and you'll at best get a good dose of crowd shaming.
