A popular British blogger may have gotten a ride from a stranger before disappearing in the French Pyrenees, sparking a search by rescue groups and authorities in two countries, according to reports.

The reports say Esther Dingley, 37, was last heard from Nov. 22 in the mountains in Luchonnais. She and her boyfriend write a widely-read blog documenting their hiking adventures. The search involves French and Spanish police.

On Friday, the BBC reported that the search for the woman had been halted due to bad weather.
