Once you and your son have made the commitment to become Adventure Guides in the HUYA Big Sky Expedition, you will need to follow these three simple steps:

1. Choose a Circle

It is best to contact the Expedition Navigator to discuss which one of the five Circles would be the best fit for you and your son.  The Expedition Navigator will help you make the best decision before joining.  You and your son are more than welcome to visit the Circle to make sure that the Circle is a good fit before making your final decision.  If you are joining a Circle with friends or family then there is no need to contact the Expedition Navigator.
