Paramount Studio Tour
It's always been a thrill to drive on Melrose past the Paramount Pictures lot and spy the huge blue-sky backdrop looming behind its pearly gates. Why not get an up-close viewing? These days you don't have to name-drop a big agent to get past the guard. And if you ask us, just strolling the stage streets that our favorite stars once walked (Mae West, Alfred Hitchcock, and Audrey Hepburn all famously have) is enough to give us chills of nostalgia. Hop across the street to Lucy's El Adobe Cafe to wrap up a cinematic day with cheese enchiladas, chicken tostadas, and (ahem, did we already mention these elsewhere?) margaritas!
5555 Melrose Avenue (at Windsor Boulevard); 323-956-1777; Lucy's El Adobe, 5536 Melrose Ave (near North Plymouth Boulevard); 323-462-9421.

Starline Tours and the TMZ Tour
You've seen the big red double-deckers all over town, now get hip to the hype: These Brit-style buses will take you all over town to every major attraction and point of interest the city has to offer. The best part? You can take the tour for as little or as much as you want, and even go back the next day (a "hop on, hop off" $40 adult ticket is good for a full 24 hours!). Feeling the need to take your 'bloid addiction live? Starline has now partnered with TMZ to bring you the latest in celebrity secrets and hot spots, so snag a seat and let the hilarity ensue!
Forecourt of Grauman's Chinese Theatre, 6925 Hollywood Boulevard (near North Orange Drive); 800-959-3131.

Warner Brothers Studio Tour
The Warner Brothers water tower was cemented in our preadolescent brains as an entertainment-industry icon when we were just kids watching Saturday morning cartoons. Now, you can tour the lot where Bugs Bunny got his big break, and see the studios of small-screen hits like The Ellen Degeneres Show and Two and a Half Men. Who knows? You might even get to bust a move with Ellen before she steps in front of the cameras!
Warner Brothers Studio Tour, 3400 West Riverside Drive (near West Olive Avenue); 877-492-8687.

Ripley's Believe It Or Not! Museum
The doors of this wacky Hollywood spot closed late last year — but not for long — the Odditorium reopened just weeks later with an even wider, weirder assortment of spectacles on view. L.A. isn't just glitz, it's also about kitsch, and Ripley's is where to go to get it by the bucketful. Our favorites are the skull collection (made of every material imaginable), and the taxidermy two-headed goats (hey, weird things happen out on the frontier)!
6780 Hollywood Boulevard (near Highland Avenue); 323-466-6335.
