Until March 2008, Oakwood Leisure Ltd. was owned and developed by the McNamara family, Pembrokeshire farmland owners who diversified into the
leisure industry in 1987 after the introduction of
milk quotas. The park took twelve months to research. A
gauge narrow-gauge railway opened at the park in 1987, providing a transport link between the amusement park and the car park. The park also included
BMX courses, a wooden play
fort, a 3D cinema show, and
go-karts. Following an increase in visitor numbers after the installation of the Snake River Falls
water slide in 1994, management decided to pursue the development of the park into a more thrilling park. In 1996, the park installed a
wooden roller coaster built by
Custom Coasters International at a cost of £1.7 million. The coaster, Megafobia, boosted the park's attendance to 500,000 visitors in one season for the first time in the park's history. In 1996, Oakwood also began an annual After Dark event, with late-night opening, fireworks, entertainment, and discounted evening entry. Several major additions would follow in the coming years. In 1997, the park purchased Vertigo, a
Skycoaster. Bounce, a
drop tower, opened in 1999. Hydro (later Drenched), a
shoot the chute, was installed in 2002, followed by Speed: No Limits, a steel roller coaster, in 2006. The only themed area in the park began as the
wild west-themed "Jake's Town". In 2000, the area was rethemed as "New Orleans" with the opening of a new
dark ride, Voodoo Mansion. Several of the other rides in the section were rethemed to match the new theme during this time as well. The park was sold to
Aspro Parks of Spain in March 2008. The New Orleans area was reverted to a wild west theme in 2012. Later that year, the park announced that it was entering a five-year investment plan, beginning with the redevelopment of the Kidz World section into Neverland for the 2013 season. This redevelopment was completed, and opened to the public on 23 May 2013. A second themed children's area, "Circus Land", was also introduced in 2013. A themed soundtrack was introduced in 2018, produced by Nick Hutson, including songs for the park itself, the After Dark event, and Megafobia. On 4 March 2025, it was announced that Oakwood Theme Park would permanently cease operations. Dismantling and removal of the rides and attractions commenced soon afterward. Speed: No Limits was purchased and relocated to the amusement park Walygator Sud-Ouest in
Agen, France. ==Former rides and attractions==
