The Dueling Dragons rollercoasters at Universal's Islands of Adventure are set to reopen on March 18, having undergone refurbishment ahead of the opening of the Wizarding World of Harry Potter.
The date is listed on Universal Orlando's ">official website. Dueling Dragons is to be renamed Dragon Challenge when the Wizarding World opens, which is due to be some time prior to May 28. However, it is not yet clear whether the ride's updated queue and redecorated trains will be in use when it reopens, or whether these elements will be saved until the rest of the Potter-themed area opens.
Dragon Challenge will have a new storyline based on the Triwizard Tournament as featured in Harry Potter and the Goblet of Fire. The ride's two tracks, Fire and Ice, will be renamed as the Hungarian Horntail and the Chinese Fireball, while Universal has promised that "guests will marvel at the blazing Goblet of Fire and the shining Triwizard Cup" as they pass through the ride's rethemed queue.
The original Dueling Dragons queue system has been closed for several months to allow construction of the new one, with riders entering through the ride's exit instead. Universal could potentially continue with this arrangement until the rest of the Wizarding World is ready to welcome guests.
Full details of the attractions, restaurants and shops that will form part of the Wizarding World of Harry Potter can be found in TPT's recent news story.
