Possibly Adelaide’s most decorated tunnels, Zorgas Tomb is painted with well over 200 graffiti and street artworks.
About 800m in is a large junction — take the right most fork. Continuing on it turns into a back-breaker. You may choose to turn back here but for those more adventurous; you’ll get to see where it ends.
Just up the South Eastern Freeway is the Littlehampton Twin tunnel system.
The eastern-most tunnel is a concrete box culvert stormwater tunnel. What’s most intriguing about this tunnel is the old telegraph wiring traversing the full length of the ceiling.
The second western-most tunnel is a 96m long ARMCO railway tunnel — the SteamRanger’s only tunnel! It was installed when the South Eastern Freeway was built and replaced an open rail cutting known as McGrath’s Cutting.
You enter Cafe Dianetics downstream at the river outlet. Choose either of the two tunnels, they both go the same way. At the first junction room it converts into a single tunnel which then takes you to the ‘Double Waterfall’.
Once again you can take either drain. The next junction will present you with three options, the far right pipe will take you up to the ‘Candle Chamber’ where small candles sit ready for use.
Back out and onward upstream will take you to the ‘Grill Room’ — an overflow inlet for a creek that runs parallel to the drain. To exit, the grill can be lifted if you have the strength, but let me tell you: it’s no lightweight structure!
