First unveiled earlier this year, the Destination Hillend proposals will see the UK’s highest zip line and longest alpine coaster built into the Midlothian hillside.

The project could also include a new reception building, food court, shops, activity dome and glamping wigwams as well as a hotel and freestyle jump slope extension.

The local authority said the investment should generate income to partially help offset the impact of continued restraints on public sector funding.

At the full council meeting on Tuesday, councillors approved a number of recommendations including the cash injection, phased over three financial years between 2019 and 2022.

As well as approving the funding from the General Services Capital Plan, councillors agreed to market and sell the site earmarked for a hotel.

Detailed planning, delivery and procurement of the project will now get underway and further reports will be brought back to council to update councillors on progress.
