The requirements to enter Chile are the same since November 2021:
Negative PCR 72h at most before your travel
Complete vaccination scheme, validated online at https://mevacuno.gob.cl.
This was highly problematic. The site was not working well, zero support and zero feedback.
The crew of Sonabia 2 spent 23 days in quarantine to validate our vaccines.
13 attempts to sign up, 7 attempts to validate our vaccines, 5 different browsers before suceeding.
This had negative consequences for Chile and for the potential visitors.
During the last season, in Puerto Williams, there were chilean tourists but much less foreign visitors than in former years.
Today the authorities grant that the process is completed within 48 hours.
I tested (2022 07 18) and it is true! within 2 days my last vaccine was validated. However, I was already registered on the site and my previous vaccines were already accepted.
When your vaccines are validated, the site delivers a “pase de movilidad”, and a form C19, declaration to enter Chile. You have to present both at the boarder (paper or phone).
