Dollywood’s NightFlight Expedition is One of the Most Complex Rides in the World — Here's How It Works
The latest ride at Dollywood combines a dark ride, whitewater rafting, a water splashdown, and a roller coaster into an extraordinary five-and-a-half-minute indoor experience.

Designed by Mack Rides, Dollywood’s NightFlight Expedition uses a prototype hybrid system. Ride vehicles are fully custom-designed as boats that rock, float, and tilt to simulate actual whitewater rafting—while remaining completely and safely tethered to a specially designed track. There are eleven boats in all but only between six and nine are typically running.
The story that the ride is based on is that a few naturalists are searching for the origin of bioluminescence in the Smokey Mountains. They’ve heard about a secret hidden lake where it all starts, and they want to take you there.
From this simple storyline, riders are engaged in a ride that flies, travels over the ground, and floats in water all the way to the lake. There is also a backward drop during the ride to add excitement and surprise. As riders travel along the track, the story is narrated through speakers in the ride seats as well as outside the seats. Decibel Studios was selected as the technology integrator for a 14-display feature video wall. Outside the boats these LED displays provide a large, curved video screen that provide fantastic scenes as the ride progresses.
NightFlight Expedition Technology
As one of the most complex theme park rides in the world, the NightFlight Expedition incorporates an EMIS (Energy Management Information System) as part of its automation. An EMIS includes comprehensive software, data acquisition, and analytics used to monitor all aspects of the ride. This automation system controls the linear synchronous motors (LSM) where magnetic-based controls are embedded between the track rails and are able to precisely propel the vehicles forward or backward, adjust speeds up to 29mph, and lock and unlock the boat depending on whether it is floating in water or must navigate vertical elements such as elevators. This approach, rather than using traditional chain lifts provides greater precision and safety features.
When the ride starts, a computer sends alternating electrical currents through the track stators, creating a moving magnetic wave. By perfectly timing the alternating pulses of attraction and repulsion, the track magnets literally push and pull the train's permanent magnets down the line, smoothly locking it to the waves and catapulting it to high speeds.
The LSM technology relies entirely on magnetic fields, eliminating the need for cables, winches, or catches that can break or wear down. This leads to high levels of mechanical reliability. In addition, precision control is attainable using computers to control the boat’s exact position and speed down to the millisecond. This allows for more ride functions including multiple launches, speed changes, and backward motion throughout the ride. Reversing the magnetic fields also allows the system to brake or slow down to accommodate incoming vehicles for safety reasons.
During one ride segment a motion simulator takes over, using three actuators to make the vehicle tilt and roll. During all aspects of the ride, the boat never truly leaves the track, even when it is floating on water. Built as a turnkey system, Mack Rides won the IAAPA award last year for its design.
The ride uses RFID (Radio-Frequency Identification) to provide RF triggers for the control of each segment of ride maneuvers during the five and a half minutes. This method easily handles the critical timing of media in conjunction with all of the mechanical and physical operations of the ride—including audio, lighting, and video.
Since the ride incorporates a continuously moving boat loading system it can maintain a throughput capacity of roughly 1,200 guests per hour. Having data and control over each boat, the ride operators are able to slow the ride whenever they need to use a transfer table to swap out a vehicle. As a continuous flow ride, slowing the ride never interferes with its operation.
Ride hydroengineering includes bringing the water in and out using large scale electric pumps as well as flow control valves, miles of piping. All of the water control elements are housed inside the building to keep the water safe. The hydroengineering company that provided all of the water elements for NightFlight Expedition is the French engineering firm, Hydrostadium, the same company that created the kayaking course at the 2024 Olympics. NightFlight Expedition is a shorter ride but still uses nearly 500,000 gallons of water in a closed system with filtration. The fully operational filtration system was manufactured by Sultzer.
The NightFlight Expedition is a 100% indoor ride, residing inside a 44,000 square foot building. It includes a massive media turntable and curved projection screens to simulate the nighttime flight over the Smoky Mountains. The end of the ride blends the high-resolution digital displays with 1,200 synchronous physical fireflies along with engaging lighting, provided by Bandit Lites, all of which is programmed to match the storyline.
