Sphere Games360 in Chattanooga: Zorbing on the Tennessee River
Sphere Games360 is an outdoor adventure operator that specializes in zorbing, the activity of rolling downhill inside a giant inflatable sphere, using the Tennessee River valley's sloped terrain near downtown Chattanooga as its venue.
What zorbing is and why Sphere Games360 exists
Zorbing involves climbing into a harness inside a 12-foot transparent plastic ball, then rolling down a grassy slope while the sphere tumbles around you. The operator controls descent speed via an air valve; you experience the sensation of falling without the impact. The sport originated in New Zealand in the late 1990s and remains niche in the United States. Sphere Games360 is one of only two active zorbing operations in Tennessee, and the only one in the Chattanooga metro area, making it a rare addition to the region's adventure activity roster rather than a crowded category.
How the experience works and pricing
Sessions run in 20-minute blocks and accommodate one person per sphere. The cost is $59 per person for a single run down a 300-foot slope, or $99 for two consecutive descents. Group discounts apply at four participants or more, reducing the per-person rate to $45 for a single run. All participants must be at least 10 years old and weigh between 60 and 300 pounds; the age requirement reflects safety protocols around sphere inflation and harness fit rather than arbitrary restrictions.
The operator provides the sphere, harness, and all safety equipment. Before rolling, you spend approximately five minutes in briefing and suit-up, then the actual descent lasts 45 seconds to 2 minutes depending on slope variables and descent speed preference. The sphere is cleaned and reinflated between each session.
When Sphere Games360 operates and how to reach it
The business operates seasonally from May through September, Thursday through Sunday, with sessions starting at 10 a.m. and the final session at 4 p.m. Hours are subject to weather; heavy rain cancels operations, and the slope becomes unavailable. Verify current hours and book in advance via phone, as walk-ins are not accepted and availability fills on weekends. Parking is roadside; there is no dedicated lot.
The venue is located on a private property with river views approximately 10 minutes outside downtown Chattanooga near Signal Mountain. GPS coordinates or specific street address are best confirmed directly with the operator, as the site is not immediately visible from main roads.
How zorbing at Sphere Games360 compares to other adventure activities in Chattanooga
Chattanooga offers several outdoor activities that share zorbing's novelty factor but differ in execution. Whitewater rafting on the Tennessee River involves group trips, wetsuit wear, physical exertion against water resistance, and 2–3 hour commitments; zorbing is solo, fully clothed, passive, and lasts under 20 minutes. Zip lining through the canopy at local providers involves suspension harness wear and multiple launches across forest lines; zorbing is ground-based rolling with no height exposure. Both zip lining and rafting occur year-round and accommodate larger groups. Zorbing is distinctly the shortest, slowest-paced, and most accessible high-adrenaline activity in terms of fitness demand.
Zorbing does not overlap with other Chattanooga activity subcategories, which is partly why it attracts visitors specifically seeking something outside the standard outdoor recreation menu.
Who should book a session and who should not
Zorbing suits people who want a low-impact, visually novel experience; children ages 10–17 who cannot yet participate in whitewater rafting; and visitors seeking a short, photograph-worthy activity that does not require serious athletic ability or prior training. It appeals to families, birthday groups, and tourists looking for a talking point that does not exist in many other U.S. cities.
Those prone to motion sickness should skip zorbing, as the tumbling motion inside the sphere is not the same as a roller coaster but does move rapidly in all directions. People with back or neck pain, despite the lack of impact, should consult the operator before booking; harness pressure and tumbling may aggravate certain conditions. Solo travelers without group bookings will find themselves at the mercy of off-peak scheduling and the 20-minute time commitment is marginal for trip planning.
First visit: what to expect
Arrive 10 minutes early to park roadside and find the staging area. You will be briefed on harness fitting and the descent pace you prefer (slow, medium, or fast determines air valve control). The operator will help you into the sphere and verify that the harness is snug but not restricting breathing. Once you are inside, the sphere is sealed and the operator guides you to the top of the slope. You will feel the initial shift as the sphere begins to move, then the full tumble begins; the transparent plastic means you see the ground, sky, and slope moving around you continuously. The descent is disorienting in a way that photographs do not capture. Upon stopping, the operator opens the sphere, helps you out of the harness, and offers water.
Why Sphere Games360 belongs in Chattanooga's activity guide
Chattanooga's adventure calendar centers on river and rock activities; zorbing fills a gap for novelty seekers and families wanting something outside the standard kayaking and climbing circuit. It is expensive relative to its duration, but the specificity of the experience and the rarity of zorbing in the Southeast justify its inclusion as a distinct offering rather than a generic thrill activity.
