Jay Creek flows into a permanent waterhole in the West MacDonnell Ranges, west of Alice Springs.
Jay Creek is also at the Trailhead for Sections 2 and 3 of the Larapinta Trail, a 231 kilometre trek through the ranges.
The creek flows through a rugged gorge, at the southern end of which is a deep permanent pool known as Fish Hole. Vehicle access to Jay Creek is by four-wheel drive and camping is permitted for Larapinta Trail walkers only.
The walk to Jay Creek (Section 2) starts at Simpsons Gap and takes you along a high ridgeline with great views of the surrounding ranges. Look out for euros (wallaroos) taking shelter in the overhanging boulders. You pass through a large area of mulga woodland before arriving at Jay Creek.
