An Earth Quest game will reward interest in the environment with prizes during the Earth Fest at Audubon Zoo on Saturday.

Exhibitors representing more than two dozen nonprofits, government agencies and businesses involved with environmental issues will be on hand throughout the day to assist with answering questions for prizes in the game.

Food from local vendors and handmade crafts will be available for purchase. Rich Collins will headline a full day of entertainment at the Capital One Pavilion, beginning at 3 p.m., after The Anteeks at 12:30 p.m. and the winners of the Ronald McDonald House Crescent City Talent Showcase at 10 a.m.

Audubon Zoo is at 6500 Magazine St., New Orleans. Earth Fest is included with Audubon Zoo membership or admission. Zoo tickets are $19.95 for adults and $14.95 for seniors and children. The zoo is open from 10 a.m. to 6 p.m. Saturday. No outside food or beverage will be allowed in Audubon Zoo during Earth Fest.

Along with the Earth Fest celebration, Saturday is opening day for the Cool Zoo splash park and the Gator Run lazy river in Audubon Zoo. Because of spring break, Cool Zoo and Gator Run will open daily from March 19 to April 3. Admission to Cool Zoo, including Gator Run, is $10 for Audubon Nature Institute members and $12 for nonmembers, plus Audubon Zoo admission.

Cool Zoo and Gator run will open on weekends only from April 4 to May 15. The water attractions will open daily from May 16 through Aug. 14, before shifting to a weekends-only schedule from Aug. 15 through Oct. 2, when the water park will close for the season.
