There’s no better place to swim than Key Largo’s clear-blue waters, but if you want a change of pace and scenery, check out Jacobs Aquatic Center. It offers three swimming pools, which include a children’s play area complete with a lookalike pirate ship and water slides. Family Rates are offered, and include 4 people for a flat rate of $25 on weekdays, and $30 on Saturdays, Sundays and holidays. Each additional child costs $5.
