Overview

Significant efforts have been made through donations and in-kind works to prepare for public use of the tunnel.

The Regional District of Okanagan-Similkameen (RDOS) is working with the Woodwackers 2.0 community group,
Recreation Sites and Trails BC, and several local contractors to restore Adra Tunnel.

The restoration project has made significant progress and is in the final stages of the approval process.

Please note Adra Tunnel remains closed to the public until further notice.

Woodwackers 2.0

For more than 40 years, the Adra Tunnel, a century-old engineering marvel, was closed to the public. The original Woodwackers, a community group from Naramata, made efforts to reopen it as part of their contributions to the Kettle Valley Rail (KVR) Trail.

In 2021, a diverse community network spanning generations and industries united to continue the Woodwackers' work.

Woodwackers 2.0 believe in the trail network's value, fostering a healthy community and unlocking tourism, recreation, and economic prosperity for the Okanagan.

Woodwackers 2.0 would like to thank all the generous donors, volunteers, and local businesses who have contributed to making this project a success, including George and Sylvia Melville who donated $100,000. Their invaluable support will help cover additional costs required to complete the project.

The significance of the Adra Tunnel extends far beyond its 1,600 feet (487 metres):

  • Connection: The tunnel will facilitate cyclists riding from Penticton to Kelowna, bridging communities like never before.
  • Heritage: An engineering feat from more than 10 years ago, it preserves the vision, labour, and ingenuity of past generations.
  • Trail Network: It strengthens the KVR's reputation as a world-class network of hiking and biking trails.
  • Destination: With support from local architects, Adra Tunnel is poised to become a destination similar to Myra Canyon.
