Spend the fourth day enjoying outdoor activities in Palm Beach. Start your morning with a round of golf at one of the world-class golf courses in the area. Afterward, head to Peanut Island for snorkeling or kayaking. This small island offers pristine beaches, clear waters, and abundant marine life. In the afternoon, explore the nature trails at the Grassy Waters Preserve or go paddleboarding on the calm waters of Lake Worth Lagoon.
