Koinonia Conference Grounds is a retreat, event, and camp destination set among the redwoods of California’s Santa Cruz Mountains, near Watsonville. Its mission is to provide guests with a peaceful, rejuvenating environment, supported by modern accommodations, meals, and activities for a range of ages. The grounds welcome guest groups seeking a place to gather and offer lodging, dining, and general spaces for retreats and events.

Faith is central to Koinonia’s approach: the organization aims to offer a safe, supportive setting where people can grow in their faith and deepen their relationship with God. It also emphasizes welcome and community, inviting people from all backgrounds to take part. Outdoor and recreational options include hiking, a giant slide, archery, sports, laser tag, and pickleball.

Koinonia’s programs include summer camps for children, junior high and high school students, young adults, and families, as well as a New Year’s family camp and an Adventure Program.
