Six Flags Magic Mountain vs Universal Studios Hollywood

Six Flags Magic Mountain in Valencia, California, holds the world record for most roller coasters at a single park - currently 20 distinct coasters. Highlights include X2 (a 4-D prototype), Twisted Colossus, Tatsu (a flying coaster), Full Throttle, Superman: Escape from Krypton, Goliath, and Wonder Woman Flight of Courage. The park's hilly footprint gives many rides dramatic terrain-following drops.

Magic Mountain's LA-area weekend visits, US school holidays, Fright Fest and Holiday in the Park events drive peak crowds. Weekdays outside school breaks can be dramatically quieter. Check live queue times for X2 and Twisted Colossus on arrival - they build up fastest - and use our crowd calendar to pick a lower-crowd midweek date if you want to ride all 20 coasters in a single day.

Universal Studios Hollywood sits in Universal City, California, combining a working film studio with a full theme park. The famous Studio Tour trams run through real backlots, while the park's themed rides include Harry Potter and the Forbidden Journey, Jurassic World – The Ride, Revenge of the Mummy, Transformers, and the newer Mario Kart: Bowser's Challenge in Super Nintendo World.

LA and Southern California visitor patterns keep Universal Hollywood busy much of the year, with US summer school holidays, Halloween Horror Nights and Christmas driving the peak. Mid-January and early September are the quietest periods. Check live queue times before committing to long waits, and use our crowd calendar to pick a weekday outside California school breaks for shorter lines.
