The best area to take smaller kids in Happy Valley is Ant Kingdom. There are cars that go up and down, as well as mini hot air balloons, spinning cups, a carousel and jumper. There were a couple roller coasters that were out of commission that day. For the very littlest ones, there is a mini-boat ride.
“Rush Hour” in Ant Kingdom: With a minimum of 1.2 meter height they were just able to ride. The thing takes you way up high and then just drops you. I was shocked they loved it and did it three times in a row.
“Jungle Racing” in Lost Maya, is a real roller coaster that they were big enough to ride with an adult. We could have done that all day if not for the long line.
--If you want to make use of the train, there is only stop in the park, and often the wait is long. The upside of that is once you get on it is a leisurely ride.
--A long roundabout walk to get into most rides – geared for crowd control on busy days but a nuisance on quieter days.
