Four adults missing in the Grampians with a six-month-old baby have been found safe and well.

The two women and two men left Hamilton with the baby around 11am on Thursday, thought to have been heading on a day-trip to Dunkeld.

They left a meal cooking in a slow cooker at the Hamilton property and didn’t take any camping gear.

A relative raised the alarm, sparking a huge air and land search.

They were found late on Friday morning.

The Nissan ute they were driving got bogged at Moora Moora Reservoir.
