Bohemian Grove is a private retreat located in Monte Rio, California, and is one of the most exclusive and secretive points of interest in the state. The location of the retreat is surrounded by towering redwood trees in a secluded area, and is accessible only to members who are invited to attend.

The Grove is particularly interesting because it is the location of the Bohemian Club's annual summer encampment, which has been held since 1878. The club is a private, all-male social club that was formed by artists, writers, musicians, and other creative professionals in the San Francisco area.

The retreat is known for its stunning natural surroundings, including a network of hiking trails that wind through the redwoods and offer breathtaking views of the Russian River. The Grove also features a man-made lake, which is used for swimming and boating, as well as a number of other outdoor activities.

One of the most unique things that visitors may see at Bohemian Grove is the ceremony known as the "Cremation of Care," which is performed during the opening night of the summer encampment. The ceremony is a theatrical production that symbolizes the release of worldly cares and the renewal of creativity and inspiration.

While the Bohemian Grove is not open to the public and is only accessible to members of the Bohemian Club, its location is certainly worth a visit for anyone who enjoys nature and wants to experience a truly unique aspect of California's cultural history.
