'Trailblazers: A Rocky Mountain Road Trip' is a BBC Two factual series where three female celebrities, Ruby Wax, Melanie Brown and Emily Atack embark on the trip of a lifetime through the Rocky Mountains. In doing so, they pay homage to and follow in the footsteps of historical pioneer Isabella Bird, who made a name for herself as an adventurer at a time when most explorers were men. They explore the people, places and curious customs of an ever-changing America, while reflecting on the changes in western society over the last 150 years and their own experiences of womanhood.
