If you have the time, a more atmospheric alternative to Seno Otway is the thriving Magellanic penguin colonies of Monumento Natural Los Pingüinos on Isla Magdalena. Five-hour ferry tours (adult/child CH$30,000/15,000) land for an hour at the island and depart the port on Tuesday, Thursday and Saturday, December through February. Confirm times in advance. Book tickets through Turismo Comapa and bring a picnic.
