Towers of sand will rise from the strand during the annual Sand Castle and Sculpture Contest at Crown Beach in Alameda, a perennial family-friendly favorite.
This year it’s on Saturday, June 8. Registration starts at 9 a.m. at the beach house near the Crown Beach entrance at Otis and Shore Line Drives. There’s a parking fee of $5 per vehicle; the competition is free of charge.
You can choose to create either a castle or sculpture in youth, family or adult divisions. Judging is at 1 p.m.; winners receive ribbons, small trophies and bragging rights. High tide is the final winner, reclaiming all contest entries.
It’s as much fun to observe as to participate; entries are always a tribute to people’s imagination and creativity. Cosponsors are the East Bay Regional Park District, Alameda Recreation & Parks and the Bay View Women’s Club.
While you’re at Crown Beach, stop by the park district information table to learn about the Healthy Parks, Healthy People initiative. For information on the contest, call 510-544-3187.
