What are Sister Crews?

Crews on a 12-Day trek will have the option to request to hike with another crew on a 12-Day trek with a matching arrival day. Lead Advisors for a 12-Day trek may select a Sister Crew as soon as they access their crew roster through the link received via email. Once a Sister Crew arrangement has been confirmed by both crews, either crew’s Lead Advisor may submit itinerary preferences for both crews when the Itinerary Selection process launches in the Spring leading up to their summer arrival at the designated time window.
