Read the article “An Aerial View”: The best way to see the Quechee Gorge is by taking a hot air balloon ride. The gorge is 165 feet deep, with the Ottauquechee River at the bottom. It was formed when glaciers melted during the last ice age and is known as Vermont's Grand Canyon. Taking a hot air balloon ride through the gorge is a unique group experience with unparalleled views—and that is only part of the tour!

Taking a ride in a hot air balloon is already a unique experience. Visitors watch as the pilot tests the air currents with a helium balloon and makes a flight plan. The balloon is laid out on the grass and filled with cool air. Then, the pilot turns on the burners, which heat the balloon's air and cause the balloon to rise. Each balloon carries up to four passengers in addition to the pilot. As a result, tourists can enjoy the experience as a private group. Once the hot air balloon is in the air, the skilled pilot puts it into the paths of different air currents. Since air currents change on a daily basis, every ride is unique.

The aerial views from the hot air balloon are unparalleled. The hot air balloon floats above the dam and waterfall. Passengers can see people lining the steel bridge over the gorge. Then the hot air balloon floats just above the river. This relaxing trip allows visitors to enjoy the rushing water and watch for wildlife in the forest. The pilot also takes the hot air balloon high into the sky. Tourists can see the nearby mountains. Since they are traveling in a hot air balloon, visitors are treated to a 360-degree view of their surroundings.

The Quechee Gorge is only part of the hot air balloon tour. Passengers also enjoy seeing covered bridges and farms. They can touch the leaves on the trees. The hot air balloon may even make a quick dip into the water! Visitors admire the beautiful villages of Vermont and take pictures of the picturesque countryside.

At the end of the tour, passengers will without a doubt say that a hot air balloon ride is the best way to see the Quechee Gorge.
