A scenic drive from Adelaide to Birdwood leads through the Torrens River Gorge to Gumeracha (gum-er-ack-a; population 1020), a hardy hillside town with a pub at the bottom (making it hard to roll home). Nearby Birdwood (population 1300) marks the finishing line for September's Bay to Birdwood classic-car rally. The rest of the year it makes a perfectly soporific Hills detour, with an excellent automotive musuem.
Back towards Woodside, Lobethal (population 2350), was established by Lutheran Pastor Fritzsche and his followers in 1842. Like Hahndorf, Lobethal was renamed during WWI − 'Tweedale' was the unfortunate choice. It's still a pious sort of town: church life plays a leading role in many locals' day-to-day lives, though the local craft-beer brewery and some excellent wineries in the surrounding hills demand reverence of a different kind.
