Westbound from Alice Springs on Larapinta Dr you come to the grave of John Flynn , the founder of the Royal Flying Doctor Service, which is topped by a boulder donated by the Arrernte people (the original was a since-returned Devil's Marble). Opposite the car park is the start of the sealed cycling track to Simpsons Gap, a recommended three- to four-hour return ride.
By road, Simpsons Gap is 22km from Alice Springs and 8km off Larapinta Dr. It's a popular picnic spot and has some excellent short walks. Early morning and late afternoon are the best time to glimpse black-footed rock wallabies. The visitor information centre is 1km from the park entrance.
