DoC says international tourists have put their best foot forward after booking opened on the Milford Track yesterday.
One in five bunks on the Great Walk were filled by overseas tourists for the upcoming season.
The four-day, Fiordland hike sold out in record time after going on sale at 9.30am on Tuesday.
"Each year we think the Milford can't sell out any faster and each year we are proven wrong," said DoC's Heritage and Visitors director Tim Bamford.
All bunks were taken in under 3 minutes on the first Great Walk for 2022/23, according to DoC.
