Two separate hikers who became disorientated while hiking on a trail near Alice Springs have been rescued by emergency services over the weekend.
Police were first notified of an overdue solo hiker who failed to return while walking along the Larapinta Trail about 9.30pm on Saturday.
The partner of the 33-year-old man told rescue crews that he was intending to hike to Millers Flat via an alternative southern route, not along the main trail.

The man's phone ran out of battery and lost contact with his partner about 1pm.
Police, along with rescue crews and volunteers, conducted an extensive search, covering an area of 134sqkm.
On Sunday about 9am, he was spotted by a helicopter and located.
A paramedic on board administered initial first aid for dehydration before the man was transported to Alice Springs Hospital. He has since been released.
Police said another rescue mission was sparked after a hiker failed to return from the same trail about 5pm.
The 40-year-old woman had intended to solo walk from Simpsons Gap to Standley Chasm, however she ran out of water and became dehydrated.

She activated her Personal Locater Beacon, and the search and rescue crew deployed a helicopter to her location, about 5km northeast of Standley Chasm, reaching her around 6.40pm.
She was mildly dehydrated but did not require medical attention.
Search coordinator acting sergeant Chris Grotherr urged anyone planning to walk along the Larapinta Trail to consider going in a group if possible, or at least with one other person.
"Be prepared with adequate supplies, including food and plenty of water, and travel with a Personal Locater Beacon, as the second hiker did in this case," he said.
"It was only through the collective efforts of a multiagency response that the initial missing hiker was located and recovered back to safety so quickly, however, had he been carrying a Personal Locater Beacon, he would have been found much sooner."
