Rainbow River is located in the town of Dunnellon, Florida, approximately 20 miles southwest of Ocala. This town is the "Gateway to the Rainbow," serving as the primary hub for visitors who want to tube, kayak, or swim in the river’s crystal-clear, 72°F waters. The river originates at Rainbow Springs State Park, which is just north of the main town center. In 2026, Dunnellon remains a charming, "Old Florida" destination that has resisted the massive overdevelopment seen in other parts of the state, maintaining its focus on eco-tourism and river life. If you're visiting for the famous "tube run," the main entry point is at the KP Hole County Park, while the state park offers a more structured experience with swimming areas and ornamental gardens, all within a five-minute drive of Dunnellon's historic downtown shops and restaurants.
