Treasure Island might lack Captain Flint’s treasure, but it is the home of three miles of golden, sandy beach. The island is a relaxing place to spend a day enjoying its treasured beach. Treasure Island is a short drive from St. Petersburg and Tampa. It is close enough that one can make day trips to visit Busch Gardens in Tampa or the Salvador Dali Museum in St. Petersburg. Yet Treasure Island is far from the hustle and bustle of the major cities.
