Depending on what kind of park you're looking for in Boca, you'll find lots to do here. First you have Sugar Sand Park for the family and kids. They have an enormous 'fort'-like structure made from wood for the kids to climb on and play hide-and-seek. There are waterguns there for hot days....the children absolutely LOVE this place. There are also courses for kids such as science and art that you can sign them up for along with all kinds of after school activities, nature trails, cultural events and more! Check them out at http://www.sugarsandpark.org/
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!
