Are there any scary rides? Like the ones from Knot's Berry Farm, for ex: rollercoasters, drops.

There are a couple roller coaster rides. These are more younger kids friendly than Knott's. Perfect for 4-6 year old I think. 2-3 year old may not be tall enough to ride them, most requires 42 inch to ride with adult and 48 inch to ride alone.

Rides here are much smaller than the bigger theme parks. Rides here are tailored more to younger kids 10 and under
