6. Go Climb That Mountain
If you only have one day to spend at The Magic Kingdom, doing the fan-famous Mountain Challenge might be a bit of a squeeze. However, this writer recommends simply just choosing your favorite. Whether it be Space, Splash, or Big Thunder Mountain, the thrills are always guaranteed. Of the three, Big Thunder Mountain is the one that fills up the fastest, so if you only have a short time there, hit that one first. Space Mountain is easily a fine second option, and by default, Splash comes in third. Whatever you decide, you’re sure to receive a heck of a ride.
