Cooyar - Muntapa Tunnel

Address: Muntapa Park, Narko QLD

Muntapa Tunnel is 287m in length making it Queensland's longest straight railway tunnel. Located 640m above sea level, it's the only tunnel that crossed between the inland and coastal sides of the Great Dividing Range, and the only one that crossed the Range summit.

While access through the tunnel is not permitted to protect an existing colony of bent winged bats, visitors can explore 30m into the space.

Muntapa Tunnel is a unique and secluded tunnel that makes for a great sightseeing experience with interpretive signage revealing its interesting history.

If you bring your dog, please keep it on-leash.

Now closed, the railway line was originally constructed to support small-scale agriculture in the area and to provide access to timber reserves at Blackbutt and Nanango.

It was situated on the branch line that opened from Oakey to Cooyar in 1913 and closed in 1964. Muntapa Tunnel serves as a reminder of the Region's pioneering days and the important role railways played in developing the area.

Muntapa Tunnel was listed on the Queensland Heritage Register on 3 May 2007 having satisfied the following criteria:
