Tourists that have been fully vaccinated will simply need to present their COVID-19 vaccination card showing that they have had all the necessary doses and they will be allowed to enter Ecuador without any further restrictions or tests. Travelers who are not yet vaccinated will have the option of showing the negative result of an antigen test or a negative PCR test taken no longer than 72 hours before arrival.
On June 7 the Minister of Tourism of Ecuador announced that Starting on July 1 people who have been fully vaccinated will no longer be required to show a negative covid test before flying to Galapagos. Travelers who are not yet vaccinated will have to show a negative PCR test taken no longer than 72 hours before traveling to the Galapagos.
The CDC is still requiring all passengers who board international flights to the US to show a negative PCR test within 3 days of boarding the flight. However there are now verified labs for Covid testing open at BOTH of the Ecuadorian international airports (in Quito and Guayaquil) for ANTIGEN testing. In Quito a lab called VIP Medical and is open 24/7. In Guayaquil a lab called VERIS and is open daily from 3:30PM to 11:00PM. The cost of the test is $40 and results are sent electronically within 30 minutes. Both cash or credit cards are accepted.
