Magellanic Penguins, Isla Magdalena
I've been to Isla Magdalena twice now (2019 and 2022) and loved it! The penguins go about their lives completely ignoring the people who walk along a set path on the island. You're supposed to keep a distance between you and the penguins and not scare them. No loud noises or fast movement. Both times I've been people are respectful and I had a great experience.
