Abyss, Steel roller coaster at Adventure World, Western Australia.

Abyss is a steel roller coaster at Adventure World in Perth that takes riders on a 630-meter journey through the park. The ride features steep drops, three inversions, and sharp turns that create intense sensations throughout the experience.

Planning for Abyss began in mid-2012, and Adventure World announced the $12 million attraction on Facebook in April 2013. Gerstlauer crews assembled the Euro-Fighter track in seven weeks after it arrived that July. The name was revealed on Friday 13 September 2013 to match the horror theme, and the ride opened on 1 November 2013 as the park's largest single investment.

The ride incorporates ancient druid guardian statues and stone structures manufactured in the Philippines to create its surrounding mythology and decorative elements.

The station sits inside the show building, so riders board in darkness before the train turns right and drops into the enclosed inline twist. The 30-metre lift hill and 100° first drop come after the train leaves the building. Four trains seat riders four abreast in two rows, and the circuit runs about two minutes.

The Abyss reaches speeds of 85 kilometers per hour and subjects riders to forces ranging from negative 1.5 to positive 4.5 times gravity.
