The Adra Tunnel is located along the KVR trail just above Naramata and runs about 490 metres long. The Adra Tunnel has been closed over 40 years (as of 2023).

The horseshoe-shaped tunnel was originally excavated in 1914 as part of the development of the Kettle Valley Railway. Rail operations stopped in the 1970s while the rail bed was bought by the provincial government in 1990.

As of this entry, a Naramata group called the Woodwackers, with support of the Regional District of Okanagan-Similkameen, has begun restoration of the tunnel and hope reopen the tunnel to the public in the near future.
