Explore the L.A. River’s parks

Why go in late spring: The Los Angeles River isn’t just the big concrete channel you know from movies. Hop on the Glendale Narrows riverside path for a leisurely 5-plus-mile (one way) bike ride or walk, and you’ll be wowed by this park-dotted green oasis that looks like … a river!

It’s not what you remember: Movie clips from Grease and Terminator 2 don’t do this river justice.

The river runs through it: The river runs 51 miles from Canoga Park, across the San Fernando Valley, past the hills of Griffith and Elysian Parks, along the east side of downtown L.A., and out to the ocean at Long Beach.

Number of bird species: 175, including herons, American coots, and black-necked stilts.

Upstream downward dog: Check out the yoga course downstream from Los Feliz Boulevard, along the east bank.

Chutney detour: India Sweets & Spices ($; 3126 Los Feliz Blvd.; 323/345-0360).

Mediterranean must: Canelé ($$$; 3219 Glendale Blvd.; 323/666-7133).
