Roe Creek is normally a dry creek, although it may occasionally have some semi-permanent waterholes along the creek. Roe Creek flows through Simpsons Gap, crossing Darken Road, then over Larapinta Drive and down through Honeymoon Gap.
During periods of heavy rain, the creek comes alive and with enough rain, swells to overflowing. It can cut off access to Simpsons Gap, when it crosses Darken Road, and when enough water flows, it can temporarily cut off access along Larapinta Drive as it flows pass through Honeymoon Gap.
Located about 20 km west of Alice Springs and previously known as Temple Bar Gap, Honeymoon Gap takes it name from a couple named Bob and Vicki Darken, who had honeymooned there in 1942.
