This newish trip deserves to become established as a MBA favourite. It's well designed with a nice mix of different activities in some spectacular settings, and well away from the crowds. The pictures really do speak for themselves, although as ever the cracking views are even better when experienced in person.
In short, just book it!
Big thank you to a group of lovely fellow travellers, our wonderful and super-enthusiastic guide Isabella, Josefina from the local supplier Birds Chile, who tagged along with us for a few days, and all the other local team (in particular the incredibly hard-working and versatile Diego at El Rincon Bonito).
A few practical points: you can leave some luggage in Puerto Varas but everything else (including your big bag if you take one on the road) has to fit into 55 litre dry bags which are then put inside the packrafts for the transfer out of El Rincon Bonito.
Maybe think about taking some binoculars and one of those waterproof phone holders for the water-based activities.
There are a few other people who probably need tipping, in addition to the ones mentioned in the FAQs: the local guides for the rafting and kayaking activities (the suggested amount was around CLP8k per person). Also Yolanda, the abuela who hosts lunch on the kayaking day.
For my trip the one group transfer was at 16. 00 on arrival and at midday on departure. The local supplier quoted USD40 for a private transfer. I took an Uber on arrival which worked fine and cost CLP16k for a 25 minute ride.
