Former campers entering 7th–12th grade can return to camp to volunteer as Habitat Heroes. In recent years, the camp has included virtual and hybrid models. Bus transportation from Alviso to Fremont is offered for campers from Santa Clara County. An At-Home Activity Packet is available with family-friendly activities to engage with nature and science at home.
