The Skyline Swansea project will include a zipline and gondola at Kilvey Hill, near Swansea.
Proposed activities include a zipline and gondola as the main attraction, along with luge rides, a sky swing and mountain bike trails.
A children’s play area is also visualised as part of the development.
F&B options would be available, with plans to build a viewing terrace and other facilities.
If plans are passed, the development is planned for a 2025 finish.
