After conducting research, it appears that there is no boat ramp specifically named "Tamiami Trail" in Florida. However, there are several boat ramps located along the Tamiami Trail, which is a major highway that runs from Tampa to Miami.

One such boat ramp is the Tamiami Canal Boat Ramp, located at latitude: 25.7532° N, longitude: 80.4857° W. This boat ramp provides access to the Tamiami Canal, which is a man-made waterway that runs from Miami to the Everglades. The Tamiami Canal Boat Ramp is a public boat ramp that is open 24 hours a day, 7 days a week. It is a single-lane ramp that is approximately 20 feet wide.

The Tamiami Canal is open to a variety of watercraft, including boats, kayaks, and canoes. However, it is important to note that all vessels must comply with Florida boating laws and regulations, including having the proper safety equipment on board and obeying speed limits and no-wake zones.

It is always important to verify the latest information regarding boat ramps and waterways before heading out on the water. Boaters should check with local authorities and consult navigational charts to ensure a safe and enjoyable boating experience.
