Mountain Adventures is a natural outdoor amusement park featuring unique activities such as OGO Balls, a variety of climbing/exploration structures, a 4,800 square foot maze, zip lines, bumper boats and much more. Wristbands allow unlimited access to all activities. Additional fun options include Vertical Trek zipline canopy tour, Paintball, facilitated team-building at the ropes course, or winter fun. Scroll to read additional information about each activity.

Roundtop is one of only 3 places in the United States where you can OGO! These balls are only available to state-licensed venues and are very different from the balls you may see for sale to the public on the internet.

OGO Balls are 11 foot diameter inflatable balls with a 6 foot ball suspended in the middle. You may also have heard them called Zorb or Zorbing. The riders climb into the inner ball and enjoys a totally unique ride down the tubing runs. OGO balls have 5 gallons of fresh water in them so you and up to two friends body surf inside during the ride.

Will I go upside down you ask? No! Because of the water you will slip and slide inside of the ball as it rolls down the hill but will not go upside down.
