Not at Henderson Bird Viewing Preserve, but Lynne is correct about the Wetlands.
You can ride bikes on the perimeter path at Wetlands Park...I misspoke for HBVP.
I'm pretty sure the answer to that question is no. You have to walk through and off this type building to get 2 The Preserve. I didn't see anybody riding bikes and I'm pretty sure that's a no-go
