I have received some private messages asking about our penguin excursion so will post it here - hoping that will help someone.
We went on a LONG day excursion from Puerto Madryn.
We went with Monica Berg - at that time - the price was approximately $150 for her services and we paid for all entrances and lunch. etc
She is a teacher, but was on vacation in January (their summer). Her husband had a vacation also, so he drove the 4 of us in their personal car.
Her email is:
(I received mail from Roberto Mateo - perhaps her friend or relative - I don't know, but that's how I contacted her)
I hope this helps.
