It's a three-minute walk from the small wooden station building of Yamanakakei Station on the JR Hanwa Line. The most popular attraction among children is the 200-meter-long "Roller Express." This roller slide features a steep slope of up to 32 degrees, landing inside a dinosaur's mouth. The large dinosaur, measuring 10 meters high, 21 meters long, and 5 meters wide, is modeled after the aggressive dinosaur "Dimetroton." Its wide, open mouth awaits visitors, and the moment they enter, a dinosaur's scream echoes throughout the area. Another attraction is the colorful red, blue, yellow, and green athletic course, "Jack and the Beanstalk," which stretches 74 meters along a steep slope, featuring stairs and tunnels. You can also see Kansai International Airport from Wanpaku Fort, a three-story wooden observation tower perched atop a mountain approximately 210 meters above sea level. Wanpaku Kingdom also features a barbecue facility, making it a popular spot for families on weekends.
