Since Clearwater and its surrounding areas are spread out, a car or rental car is necessary to get around. There are several car rental companies at the Tampa International Airport, which is about 25 minutes from Clearwater. Uber and Lyft are also available in the area. Parking is available at most attractions, but expect to pay for parking in popular areas like Clearwater Beach and the Clearwater Marine Aquarium.
If you have extra time, consider taking a day trip to Busch Gardens Tampa Bay, a theme park with roller coasters and animal exhibits. If you have less time, consider skipping Tarpon Springs and spending more time at Clearwater Beach or the Clearwater Marine Aquarium.
