Nice park with atmosphere
The main attraction is the wooden roller coaster called "Cyclone". Except for a bit of a jolt just before the second hill, this coaster rides extremely well for a woody. It is definitely worth riding more than once.
My sons really enjoyed the Go-karts --- riding them multiple times.
There were two trains also which make a complete circuit of a lake.
Other rides you will want to experience are: Zoom (a drop ride), Wild Chipmunk (metal coaster with sharp curves), Bumper cars, Electric bumper boats, and many standard "carnival-type" rides like "Egg-Beater", "Spider", "Tilt-o-whirl" and the like.
The ride operators were exceptionally friendly. And I liked how they really seemed to enjoy working there.
Personally, I liked the decor of this park. Tonnes of neon. And a style from days gone by --- very nostalgic.
The cost of this park is a great deal. At full price it is less than a third of the cost of Denver's other amusement park.
The only negative aspect we experienced at this park was that there seemed to be quite a bit of non-functioning equipment. Several bumper cars were out of commission. Only three out of six of the go-karts were working. And it appears that there was once an auto race track which has been allowed to fall into ruin.
But, all in all, this park is an exceptional value for the money, and the entire family will enjoy the visit.
