Opened in November 2005, the indoor resort features an 85-metre-high indoor mountain (equivalent to a 25-story building) with 5 slopes of varying steepness and difficulty, including a 400-metre-long run, the world's first indoor black diamond run, and various features (boxes, rails, kickers) that are changed on a regular basis. A quad lift and a tow lift carry skiers and snowboarders up the mountain. Equipment such as skis and jackets are provided with the ticket and one can buy equipment in the nearby stores. Adjoining the slopes is a 3,000-square-metre Snow Park play area comprising sled and toboggan runs, an icy body slide, climbing towers, giant snowballs and an ice cave. Ski Dubai also houses a number of penguins who are let out of their enclosures several times a day. Penguin encounters can be booked, allowing the public to interact directly with the penguins.
