Billed as a weekend of fun for kids, tweens and families over Memorial Day holiday, KidFest is back for the 24th year with new attractions, including a zip line.

On the zip line, visitors will be able to zoom three stories above the action on the festival grounds May 25-27, at Mt. Diablo High School in Concord. Also new this year is the SportStars Field of Dreams with sports activities, games and clinics, including football, baseball, basketball, golf, lacrosse, soccer, volleyball, rugby and fitness, as well as Velocity Circus with its "Monkeys in Space" shows each day.

The most popular KidFest attraction -- Wild About Monkeys -- is back, with three shows daily followed by a meet-and-greet, and visitors can again visit with Dora and Diego from "Dora the Explorer."

The thrills of the Clayton Bikes BMX Stunt Team return with three performances each day, and martial arts, and music and dance performances are planned throughout the weekend.

More than 20 rides, including the Ferris wheel, pony rides, trampoline, petting zoo, rock climbing wall and more will be on site as well as more than 100 arts, crafts and educational vendor booths, and food court, open throughout the weekend.

The festival is a fundraiser for HOSA (Health Occupations Students of America), the future health care professionals group from John Muir Medical Center, Concord; and the Food Bank of Contra Costa and Solano. Additionally, the primary recipient this year is Mt. Diablo High School and its athletic teams and school groups who should receive more than $7,000, according to festival producer Jay Bedecarre.

Admission to KidFest is $5 per person with a can of food for the Food Bank of Contra Costa and Solano, or $6 without a canned food donation. Babies under 24 months old and seniors 65 and older are free. Tesoro will donate $1 to the food bank for every can collected at the festival.

The event will be held from 10 a.m. to 6 p.m. Saturday-Monday, May 25-27, at Mt. Diablo High School, 2450 Grant St. in downtown Concord. For detailed information about showtimes and dates, and all events, visit www.kidfestconcord.com.
