A new ocean sustainability-focused festival is kicking off in Belmont Shore Saturday, July 16 where attendees can participate in a beach clean-up, check out Formula Kiteboarding and KiteFoil portions of the West Marine U.S. Open regatta, and soak up myriad beach festivities pertaining to the ocean and sustainability.

Some of these activities include a public sand building contest (with a spotlight on a professional sand castle builder), live art demonstrations and education on sailing and kiteboarding, complimentary food and beverages and more.

The festival, which is from noon to 4 p.m., is free and open to the public. Click here for more information and to RSVP.

Sea Change Festival is at 79 Claremont Place.

THE DINNER DETECTIVE –  COURTYARD BY MARRIOTT LONG BEACH DOWNTOWN (Saturday)

Similar to the premise of the classic board game “Clue,” this interactive theater experience invites guests to help solve a murder while dining on a four-course meal.

The Dinner Detective, heralded by the company as America’s largest interactive comedy murder mystery dinner show, will unfold Saturday, July 16 at the Courtyard by Marriott Long Beach Downtown.

What’s fun about the show is how you can approach your experience. If being part of the action sounds like your kind of party, all you have to do is speak up and make yourself part of the story. But, you can also opt for a more traditional theater experience and watch the drama unfold while you dine and drink. And yes, there is a full bar available on site.

Tickets cost $69.95. Click here for more information and to purchase tickets.

The Courtyard by Marriott Long Beach Downtown is at 500 E. First St.
