Attention: Roundtop Summer Adventures is currently closed.

Here at Roundtop, we have been actively working with our local partners and health officials to ensure the health and wellbeing of our guests, employees, and local community remains our top priority. 

With this, and after careful consideration, we have decided to hold off on opening for summer operations at this time. We will be sure to update you all when we have more information on operations. 

While we will miss seeing you at the mountain, we are confident that we doing the right thing for our employees and guests as we adapt and prepare for what we foresee to be an amazing winter ahead of us. 

Dual Zip Lines

Our longest zip lines ever. Begin from a new top level of the Canopy Crawl, zip over a pond to the base of the Ramrod Triple Chair.

Mountain Adventures is the perfect activity for a group!

Not only are there activities for people of all interest levels, but you only have to pay for people who are doing the activities!  Unlike a traditional amusement park where you have to pay for everyone who enters the gate, at Mountain Adventures, you are welcome to chaperone your group, without actually doing the activities, at no charge!

Are you a group leader planning for the future?

OGO Balls

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.

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.
