Event Details:
Family Funfest at Settlers Landing festivities start at 6:30PM with lots of music and entertainment, including a twelve piece Sousa band, family activities, prizes and giveaways, popcorn balls, and more! Best viewing areas are from the Nautica Pavilion to Shooters and the Nautica Boardwalk on the Flats west bank, Settler?s landing on the east bank, and Whiskey Island.
I've launched off the beach at Wendy Park several times, but wonder whether they would close it off for this event? Parking will be a nightmare. You could probably launch from Edgewater Park and paddle as close as they'll let you.
