It's barefoot time at the beach — time for the Barefoot Wine Beach Rescue Project, that is.

Mark you calendars. Barefoot Wine and the Surfrider Foundation are teaming up to keep 20 beaches across America barefoot-friendly, with Ala Moana Beach Park as one of their stops, on Saturday, Aug. 13.

The beach cleanups are all happening the same day — from Long Beach, Calif. to Ft. Lauderdale, Fla.

Volunteers are invited to help clean up the park, and then celebrate afterwards at Dave & Buster's across the street at Ward.

The beach cleanup will take place from 10 a.m. to noon, while the celebration featuring Barefoot Wine and surf-inspired fare at Dave & Busters Ward starts at noon (only volunteers 21 and older are able to attend).

The rescue project is in its fifth year. If you swim, paddle, hang out at Ala Moana Beach Park, here's your chance to give back. RSVP at BeachRescue2011.com.
