Following a takeover by the Cursach Hotel Group, the former Mallorca Rocks hotel is undergoing a €10m (US$11.3m, £7.4m) redevelopment of its facilities, which will now include a new beach club, stage area and an over 18s waterpark under its new name BH Mallorca.

Scheduled to open on 30 April, the Twisted waterpark on the island of Majorca, Spain, will include the only Aqualoop slide in Europe. The slide – designed by WhiteWater West – drops riders through a trap door before sending them at speeds of up to 40mph (60kmph) into a freefall and then loop. Amusement Logic has provided the rest of the park’s slides, which include a four-lane race slide.

All located within the BH Mallorca complex, the development also includes what will be Majorca’s only open-air festival venue, which will host some of the world’s biggest DJs through the summer months, and Island Beach Club – a pool area with a resident DJ and cabanas.

The development is targeted at tourists aged 18 to 30 and is aiming to turn the hotel into an all-in-one holiday complex. Guests will have unlimited access to all three areas included in their stay, with food and drinks also included between 11am and 8pm. Further developments on the rebranded hotel are expected at the end of the tourist season, to be completed in 2016.
