Simpsons Gap
The closest gorge to Alice Springs—there's even a bicycle and walking track from the city center—greets you with views of stark-white ghost gums (Australian evergreen trees), red rocks, and gorgeous, purple-haze mountains that provide a taste of scenery to be seen farther into the ranges. Swimming is not permitted, but come in the morning and late afternoon for a chance to catch a glimpse of rock wallabies.
