Gumbo Limbo is a must for children, too. They will love exploring the forest and spider webs, tower lookouts and the intracoastal! More info can be found at http://www.gumbolimbo.org/aboutus.php
This place is a dull 20 acres of nature reserve---every child's dream for animals and insects and the stranding center, too.
The best part of Boca Raton are the beaches. They are clean, uncrowded with perfect turquoise water....need I say more? Come with a blanket at 5am and watch the sunrise with it's rainbow of colors and clouds on the horizon.....really beautiful!
