Multiple theme parks are set to close their doors permanently in 2026, including cherished attractions in the UK and US, as rising operational costs take their toll.
In Somerset, Brean Theme Park entered liquidation at the start of 2026, becoming one of several parks ceasing operations after disappointing trading periods.
Glenwood Caverns in Colorado filed for Chapter 11 bankruptcy protection in February following a series of financial and reputational challenges.
Theme park operator Six Flags announced it would shutter six "underperforming" amusement and waterpark sites in 2026, after posting losses exceeding $1.2 billion at the close of 2025.
Wild Waves Theme and Water Park in Washington State opened what has been confirmed as its final season at the end of May. Operated by Premier Parks, the park launched in 1977 and will close after nearly 50 years due to escalating expenses.
"We are thankful for our guests, team members, and the community of Federal Way for supporting Wild Waves and creating so many great memories," said Premier Parks owner and president Kieran Burke. "Unfortunately, the rising cost of ongoing operations since reopening after the COVID shutdown has generated millions in losses, forcing us to discontinue operations at the end of our 2026 season."
The final season opened on May 23 and will run until November 1, when the park shuts permanently. All 30 rides and water slides will remain operational, and season passes or packages purchased before the closure will be honored.
"In its final year, the park will celebrate memories, nostalgia, and family fun with themed events and special promotions," Burke said.
The amusement park will be replaced by a one-million-square-foot warehouse, sparking opposition from local residents. Alternative options previously considered included a hotel and convention center.
"We recognize the deep history and emotional connection many residents have with the park, and we are committed to ensuring a respectful transition while planning a project that will bring lasting benefits," said co-owner Jeff Stock in December 2025.
