The O-Bahn is a German concept. It uses buses on a concrete-guide track instead of a conventional train and carriages. The trail follows the O-Bahn for the majority of its length and, while it is predominantly a sealed shared-use path, there are sections on quiet side roads. The trail makes use of the many O-Bahn overpasses and underpasses to provide pleasant riding. The few road crossings that you will encounter are generally quiet roads that are easy to cross. There are trails on both sides of the O-Bahn but we have described the trail that provides a more scenic and continuous journey.

CBD to Paradise Interchange (11 km)

• The trail starts at the eastern end of Grenfell St in the Adelaide CBD, where the O-Bahn buses enter a tunnel before re-emerging on Hackney Rd. It’s on the southern side of the portal
• Proceed past Rymill Lake and follow the Parklands Trail to the corner of Botanic Rd and Dequetteville Tce.
• Cross Botanic Rd and follow the narrow footpath which opens up into a proper shared-use path. The Wine Centre and botanic gardens are on the left and the O-Bahn tunnel ends in the middle of the road on the right.
• Continue to the River Torrens, crossing it on the shared bridge and then turn sharp left and ride under the road bridge.
• Continue heading upstream and cross the River Torrens again, using the low-level bridge. Follow the path which is adjacent to the river, past St Peters Park on the right and St Peters Weir on the left, the path will go under an O-Bahn bridge and then continue to follow the river.
• The trail crosses the O-Bahn just past the Felixstow Reserve. This bridge crossing gives a good view of the O-Bahn track. The path continues on to the river, which is crossed using a low-level bridge then continues to the right, following the river upstream.

Paradise Interchange to Modbury (5 km)

• When the trail goes under Darley Rd, the O-Bahn track can be seen ahead and the Paradise Interchange is over Darley Rd on the right. Continue on to Brookvale Rd
• There are two options for approaching the hill on Brookvale Rd. You can ride up the steep bit or cross under the O-Bahn and ride up the less-steep Willowbrook Rd. The return trip down Brookvale Rd is a lot of fun.
• At Parsons Road turn left and then turn right into the small reserve on the corner of Parsons Road and Glenwood Walk and follow the path until you come to Lyons Road. Cross Lyons Road and follow the path adjacent to the O-Bahn and then through the bridge under the O-Bahn track. Alternatively, you can take the side trail (see below) and cross Lyons Road and follow Lyons Road until you get to the entrance to the Hope Valley Reservoir. Follow the path along the top of the Reservoir head wall then up through the park to the northwestern corner of the reserve and follow the path through the gate to reconnect with the O-Bahn Rail Trail.
• The trail continues adjacent to the O-Bahn. Take the first left turn leading under the O-Bahn track and then turn right and follow the path adjacent to the O-Bahn track.
• The trail follows the O-Bahn track, going under Reservoir Road and then exiting briefly onto Meadowvale Road to the left. Follow Meadowvale Road for 100m and then rejoin the path in the reserve on the right, following it and the O-Bahn track across a creek and up to Smart Road.
• The trail can be followed into the Tea Tree Plaza shopping centre, but this is not a bike friendly area. Your best option is to return to Adelaide on the O-Bahn trail. You may want to consider returning via the Dry Creek Trail and the City to Levels Bikeway if you have the time. 

CONNECTING PATHS

Adelaide Parklands Trail – 19.5 km

The Adelaide CBD is surrounded by a 600 m wide strip of parklands which contains gardens, sporting facilities, recreation facilities, art and cultural facilities. A myriad of trails have been constructed throughout the parklands however the council has developed a 19.5 km shared-use path that forms a loop around the city. The trail overlaps the O-Bahn trail and is the starting point for five rail trails (Gawler, Outer Harbor, Westside, Mike Turtur and Marino Rocks rail trails).

City to Levels Bikeway – 18 km

The City to Levels Bikeway links with the O-Bahn Rail Trail at Fuller Street, Walkerville. The trail is located on minor, low traffic roads and links with the Dry Creek Trail and Stockade Rail Trail.

Dry Creek Trail/Stockade Rail Trail – 17.5km

At Baymor Reserve, 804 North East Rd, Modbury, a 400m path, connects the O-Bahn Rail Trail with the Dry Creek Trail. The Dry Creek Trail extends 6.5 km northward to Wynn Vale Dam and 5 km west to link with the Stockade Rail Trail (it also connects with the City to Levels Bikeway at this point). Dry Creek Trail continues for a further 6 km to link with the Gawler Rail Trail.
