We were looking for an easy trail where my 3 and 7 year old kids could ride their bikes and the adults could walk off some thanksgiving turkey. The trail that is accessible to bikes is on the perimeter of the reserve, and winds you around a water treatment plant. Also the trail head is the neighborhood park not the nature center located a little further down the road. It was fine, but there was a lot of trash... I assume the more nature-focused experience would have been if we had just all walked and been on the better maintained reserve trails. I did run into an employee who was super helpful and very knowledgeable.
Nice and paved area and also non paved trails. Doesn't even feel like your in Vegas! It's easy to get confused though if you go through the non paved areas. Haha a lot of bench areas. Seen a few roadrunners. We went passed the big bridge and seemed like most folks were on bikes there. So it would be a Neat area to also go biking too, I'd say!
