Where is the best mall in Arvada?

Arvada doesn't have a mall of it's own. However Flatirons Mall in Broomfield and the Denver West and Colorado Mills at 1-70 and Indiana are all excellent.

I believe there are several. In the mall near the food court there's an enclosed area with plastic dinosaurs for little kids to climb on, etc. Outside there's a giant sand box area, and another area with little slides, etc.

Yes -- Flatiron Crossing. I can't think of any good malls IN Arvada -- most of the malls built during the Great Indoor Shopping heyday of the 1960's have been torn down and/or re-purposed. But Flatiron, just a little northwest of Arvada, is one of the three best malls in town. It's newer, huge, lovely, has indoor and outdoor shopping and lots of restaurants, etc. It's anchored by Nordstrom, Macy's, Dillards, etc., and has all of the shops you'd expect in an upscale shopping center.

Flatirons is my preference - great stores, easy commute up 36!
