Day trip suggestions with stroller

Hi, I have a 7 month old and I'm new to N.CA. I'm looking for ideas on safe new places to check out within 2 hrs of Lafayette. It needs to be stroller friendly please. So far I have tried: Walks:Lafayette Reservoir Lafayette-Moraga Regional Trail (both ends of the walk) Tilden Park in Orinda Iron Horse Trail Downtowns visited: Orinda (snooze) Lafayette Livermore Pleasanton (so cute!) SF Fisherman's Wharf Rockridge Danville Alameda (S. Shore walk & shopping center) Malls: Walnut Creek Livermore Outlets Stoneridge I'd love any new suggestions, as specific as possible would be great since I'm a newbie! Thanks in advance!
