The 680 acre Floyd Lamb Park is home to the historic Tule Springs Ranch and Tule Springs lake.
We went there in the Fall and it was lovely. There is a big pond with ducks and geese, lots of room for picnics or a pick-up game of football in the grass. For Las Vegas, there is a surprising amount of shade. This is a great place to take your kids on the weekend.
This location offers a lot of fishing and grassy areas to relax. There is also a place near the entrance where you can do horseback riding. Aside from the fishing there are also ducks along the water for kids to feed. Most areas are shaded enough to enjoy a walk.
