Lively book discussion groups take place several times a month and are open to the public at no charge. The library serves as the town library for Palm Beach, but memberships with borrowing privileges are available to all book lovers whether they live on the island or not.

The Children's Library invites children and families to borrow books and use computers free of charge. A free story time program is offered twice a week for preschool-aged children and special events for children of all ages are offered throughout the year.

The Four Arts Botanical Gardens are demonstration gardens designed in 1938 to help new arrivals to South Florida who were struggling with gardening in the state's tropical climate. Seven demonstration gardens illustrate different styles of landscaping and information on drought and heat tolerant plants.  Adjacent to the botanical gardens is the Philip Hulitar Sculpture Garden, which showcases carefully selected sculptures in an outdoor museum-like setting. With welcoming pergolas and a large garden pavilion, the Hulitar Sculpture Garden has become a top destination for visitors to South Florida. The gardens are open seven days a week, and there is no charge for admission.
