Universal's Island of Adventures is the larger of the two core parks - it is also the most thrilling! This is where you'll find the most Harry Potter themed rides as well, if you're a big fan! (Anyone else a Slytherin?)

I highly recommend this park for those that love thrilling and adrenaline-fueled rides.
There are numerous roller coasters, water rides, and a nice land for the kids to check out (I personally love the Seuss Land!)

I find the best parts of this park to be the Hogsmeade area due to the view of the Hogwarts castle and Jurassic Park Land. This is the type of park you can spend ALL DAY in, but you do have the option to catch the Hogwarts Express throughout the day to hop parks (if you have a park-to-park pass!)
