Best amusement parks in Riyadh

Hey guys! Been here in Riyadh for quite a while now. Quick question. I really wanted to know if there were amusement parks (the ones with rides and stuff) in Riyadh where me and my friends (note that we are males and are 18 years of age) could hang out in and seek thrills and have fun. If so, what days and for what time do they stay open?

Hello there,
I think the best place would be AlBujairi, I like its restaurants,coffee and design.
its pretty good
