Amador Vista is a great little park. It has all that you could want-- a green, grassy field, shaded playgrounds, and picnic benches.
This park is tucked away in a residential area, right next to a fire station. During my visit, there were tons of rabbits hopping around. Adorbs! And the playground area was clean and well taken care of.
If you are looking for a park to have a quiet, little picnic, Amador Vista is your place!
(Or if you are looking for Pokemon-- but that's another story!)
