LetoLeto Waterpark, a sprawling indoor attraction in Tyumen, Russia, opened its doors this week, promising to keep guests warm no matter what the weather outside.

The Sibentel Holding development has been built in partnership with Turkey’s Polin Waterparks and is being billed as the largest in Russia.

LetoLeto boasts tens of water attractions, including more than a kilometre’s worth of thrilling slides, a 21-metre tall slide, a 750sq m (8,000sq ft) wave pool and a half-a-kilometre lazy river ride. Polin installed Turbolance, Windigo and Magic Hole slides.

All of this is provided in a temperature of around 28ºC. Furthermore, guests can enjoy a large children’s aquaplay area and dining zones.

The waterpark has a capacity of 2,500 and is equipped to cater for guests with disabilities. The wider complex also offers a four-star hotel.

“I am sure that LetoLeto will become one of the favourite places for family recreation for Tyumen citizens and will turn into a point of attraction for tourists from other regions of the country,” said Tyumen acting governor Alexander Moore.

“The government of the Tyumen region creates comfortable conditions for investors in all areas of our economy. The creation of an aqua park is yet another confirmation of the correctness of such a strategy.”
