Oakwood Theme Park (formerly Oakwood Leisure Park, Oakwood Coaster Country & Oakwood Park) is a theme park in Pembrokeshire, Wales. Oakwood opened in the late 1980s as a very small family park with BMXs, a wooden fort, a 3D-style cinema experience show, go-karts and a water chute ride. The park later incorporated four large thrill rides: Megafobia (1996), Vertigo (1997), Drenched (2002, as Hydro) and Speed (2006) which was a Gerstlauer Euro-Fighter roller coaster with a 97-degree drop. It was the first Euro-Fighter in the United Kingdom and was at that time the steepest roller coaster in the UK. The CCI-built wooden roller coaster Megafobia was rated by enthusiasts soon after its installation as amongst the best in Europe. In 2016, it celebrated 20 years at Oakwood. History 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. Oakwood Park Railway A gauge narrow gauge railway operates on site at Oakwood. The railway, which is well established, is not listed amongst the park's rides and attractions, but forms part of the operational infrastructure, providing a transport link between the theme park and the car park. Travelling on the railway is included in the cost of the park admission ticket. Until 2016, the railway was operated by four diesel locomotives; two were American-style (though British-built) steam outline engines, and the others were a standard diesel outline locomotive and a diesel railcar. Since 2016, only one non-themed diesel locomotive is being used, the other three locomotives having been retired. Open 20-seater "Severn Lamb" type toast rack carriages are used in warm weather, with enclosed 20-seater former Liverpool Garden Festival coaches used year-round. Development into Theme Park (1996–2008) Following an increase in visitor numbers after the arrival of the Snake River Falls water coaster in 1994, the management decided to pursue the development of the park into a more 'thrilling' theme park. In 1996, the park received a wooden roller coaster from the American firm of Custom Coasters International. Built at a cost of £1.7m, Megafobia allowed the park to reach 500,000 visitors in one season for the first time. 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
