2022 Travel Requirements due to COVID-19

At this time, all Individual Expedition participants are required to be fully vaccinated before their expedition. One of the best ways GCY can prevent the spread of COVID-19 on expeditions is to not bring it with us at the start. Because young people are traveling from across the country to join this expedition, a vaccination requirement is our most prudent option.  Please see the FAQs page for more information.

Additionally, an adult responsible for each participant is required to be within five driving hours of Flagstaff, AZ for the duration of the expedition. In the event of an evacuation, GCY will communicate with this adult, who will take responsibility for the participant once off the trip.
