Visitors exploring Jessie Gap in the East MacDonnell Ranges. Yeperenye / Emily and Jessie Gaps Nature Park is the first noticeable feature of the East MacDonnell Ranges as you drive out of Alice Springs. Pack a picnic, watch the local wildlife, or follow a short walking track into both gaps. At Emily Gap you can see a large rock painting depicting the caterpillar dreaming. The two small gaps in the Heavitree Range are important spiritual sites to the Eastern Arrernte Aboriginal people.
