You can walk cycle or drive through this 192m tunnel,
The longest unsupported tunnel in the Southern Hemisphere!
Close to the historic mining town of Mount Perry
The tunnel is on the same rail corridor as the Watawa Recreation Trail.
The tunnel was constructed in 1883/1884 as part of a railway from North Bundaberg to Mount Perry. This section of the line closed in 1960. Most of the old railway reserve is now road reserve making it unlikely that the trail could be extended.

A Gentle Introduction to Inclines: Grade 2 on the
AWTGS represents easy walking tracks that offer a slightly more challenging experience compared to Grade 1. Similar to Grade 1, no prior bushwalking experience is required. The track surface is typically hardened or compacted and may have gentle hill sections or occasional steps. The total distance of a Grade 2 walk is typically no greater than 10 kilometers. These walks are still suitable for families with a bit more experience or those seeking a gentle introduction to some inclines.
