Cassadaga (a Seneca Indian word meaning "Water beneath the rocks") is a small unincorporated community located in Volusia County, Florida, United States, just north of Deltona.

One of his spirit guides was a Native American named Seneca,[2] who had manifested to Colby during a seance in Lake Mills, Iowa.

Colby had arrived in Florida in 1875, and on December 18, 1894, the charter was granted to form The Southern Cassadaga Spiritualist Camp Meeting Association.

[2] Today, the Camp features the Cassadaga Hotel, a central auditorium, The Colby Memorial Temple, a community library, the Caesar Forman Healing Center, a Camp bookstore, a welcome center, and the Andrew Jackson Davis Educational building, used for musical performances and gatherings.

The Cassadaga Spiritualist Camp is a federal tax-exempt church currently governed by a board of trustees.
