Nine hikers, one of them ill, were airlifted Tuesday out of a remote part of Kejimkujik National Park.
RCMP Cpl. Scott MacRae said an emergency call came in Monday around 9:30 p.m. from a weak cell phone.
MacRae said it was initially thought that two hikers were in trouble.
However, authorities soon learned nine German hikers had hiked 25 kilometres when one became ill. The group became lost and called for help.
Following the cell phone call, police were able to use technology to identify the hikers' approximate location and passed along that information to park staff.
Park staff drove as far as they could and then hiked for several hours to find the hikers.
Park staff located the group deep in the woods at around 5:30 a.m. Tuesday and treated the ill hiker for what was believed to be dehydration or exhaustion.
A Department of Natural Resources helicopter was used to help get the group out of the park, MacRae said.
The hiker is expected to be fine.
